(Although... if you were looking for a step-by-step installation GUI, you've downloaded the wrong software!) While the impatient can get going immediately with some of the sample code at the bottom of this library, it's well worth reading this entire document--most of the other documentation assumes that you are familiar with these contents. --------------------------------------------------------------------------- 1. Compatibility HTML Purifier is PHP 5 only, and is actively tested from PHP 5.0.5 and up. It has no core dependencies with other libraries. PHP 4 support was deprecated on December 31, 2007 with HTML Purifier 3.0.0. HTML Purifier is not compatible with zend.ze1_compatibility_mode. These optional extensions can enhance the capabilities of HTML Purifier: * iconv : Converts text to and from non-UTF-8 encodings * bcmath : Used for unit conversion and imagecrash protection * tidy : Used for pretty-printing HTML These optional libraries can enhance the capabilities of HTML Purifier: * CSSTidy : Clean CSS stylesheets using %Core.ExtractStyleBlocks * Net_IDNA2 (PEAR) : IRI support using %Core.EnableIDNA --------------------------------------------------------------------------- 2. Reconnaissance A big plus of HTML Purifier is its inerrant support of standards, so your web-pages should be standards-compliant. (They should also use semantic markup, but that's another issue altogether, one HTML Purifier cannot fix without reading your mind.) HTML Purifier can process these doctypes: * XHTML 1.0 Transitional (default) * XHTML 1.0 Strict * HTML 4.01 Transitional * HTML 4.01 Strict * XHTML 1.1 ...and these character encodings: * UTF-8 (default) * Any encoding iconv supports (with crippled internationalization support) These defaults reflect what my choices would be if I were authoring an HTML document, however, what you choose depends on the nature of your codebase. If you don't know what doctype you are using, you can determine the doctype from this identifier at the top of your source code: ...and the character encoding from this code: If the character encoding declaration is missing, STOP NOW, and read 'docs/enduser-utf8.html' (web accessible at http://htmlpurifier.org/docs/enduser-utf8.html). In fact, even if it is present, read this document anyway, as many websites specify their document's character encoding incorrectly. --------------------------------------------------------------------------- 3. Including the library The procedure is quite simple: require_once '/path/to/library/HTMLPurifier.auto.php'; This will setup an autoloader, so the library's files are only included when you use them. Only the contents in the library/ folder are necessary, so you can remove everything else when using HTML Purifier in a production environment. If you installed HTML Purifier via PEAR, all you need to do is: require_once 'HTMLPurifier.auto.php'; Please note that the usual PEAR practice of including just the classes you want will not work with HTML Purifier's autoloading scheme. Advanced users, read on; other users can skip to section 4. Autoload compatibility ---------------------- HTML Purifier attempts to be as smart as possible when registering an autoloader, but there are some cases where you will need to change your own code to accomodate HTML Purifier. These are those cases: PHP VERSION IS LESS THAN 5.1.2, AND YOU'VE DEFINED __autoload Because spl_autoload_register() doesn't exist in early versions of PHP 5, HTML Purifier has no way of adding itself to the autoload stack. Modify your __autoload function to test HTMLPurifier_Bootstrap::autoload($class) For example, suppose your autoload function looks like this: function __autoload($class) { require str_replace('_', '/', $class) . '.php'; return true; } A modified version with HTML Purifier would look like this: function __autoload($class) { if (HTMLPurifier_Bootstrap::autoload($class)) return true; require str_replace('_', '/', $class) . '.php'; return true; } Note that there *is* some custom behavior in our autoloader; the original autoloader in our example would work for 99% of the time, but would fail when including language files. AN __autoload FUNCTION IS DECLARED AFTER OUR AUTOLOADER IS REGISTERED spl_autoload_register() has the curious behavior of disabling the existing __autoload() handler. Users need to explicitly spl_autoload_register('__autoload'). Because we use SPL when it is available, __autoload() will ALWAYS be disabled. If __autoload() is declared before HTML Purifier is loaded, this is not a problem: HTML Purifier will register the function for you. But if it is declared afterwards, it will mysteriously not work. This snippet of code (after your autoloader is defined) will fix it: spl_autoload_register('__autoload') Users should also be on guard if they use a version of PHP previous to 5.1.2 without an autoloader--HTML Purifier will define __autoload() for you, which can collide with an autoloader that was added by *you* later. For better performance ---------------------- Opcode caches, which greatly speed up PHP initialization for scripts with large amounts of code (HTML Purifier included), don't like autoloaders. We offer an include file that includes all of HTML Purifier's files in one go in an opcode cache friendly manner: // If /path/to/library isn't already in your include path, uncomment // the below line: // require '/path/to/library/HTMLPurifier.path.php'; require 'HTMLPurifier.includes.php'; Optional components still need to be included--you'll know if you try to use a feature and you get a class doesn't exists error! The autoloader can be used in conjunction with this approach to catch classes that are missing. Simply add this afterwards: require 'HTMLPurifier.autoload.php'; Standalone version ------------------ HTML Purifier has a standalone distribution; you can also generate a standalone file from the full version by running the script maintenance/generate-standalone.php . The standalone version has the benefit of having most of its code in one file, so parsing is much faster and the library is easier to manage. If HTMLPurifier.standalone.php exists in the library directory, you can use it like this: require '/path/to/HTMLPurifier.standalone.php'; This is equivalent to including HTMLPurifier.includes.php, except that the contents of standalone/ will be added to your path. To override this behavior, specify a new HTMLPURIFIER_PREFIX where standalone files can be found (usually, this will be one directory up, the "true" library directory in full distributions). Don't forget to set your path too! The autoloader can be added to the end to ensure the classes are loaded when necessary; otherwise you can manually include them. To use the autoloader, use this: require 'HTMLPurifier.autoload.php'; For advanced users ------------------ HTMLPurifier.auto.php performs a number of operations that can be done individually. These are: HTMLPurifier.path.php Puts /path/to/library in the include path. For high performance, this should be done in php.ini. HTMLPurifier.autoload.php Registers our autoload handler HTMLPurifier_Bootstrap::autoload($class). You can do these operations by yourself--in fact, you must modify your own autoload handler if you are using a version of PHP earlier than PHP 5.1.2 (See "Autoload compatibility" above). --------------------------------------------------------------------------- 4. Configuration HTML Purifier is designed to run out-of-the-box, but occasionally HTML Purifier needs to be told what to do. If you answer no to any of these questions, read on; otherwise, you can skip to the next section (or, if you're into configuring things just for the heck of it, skip to 4.3). * Am I using UTF-8? * Am I using XHTML 1.0 Transitional? If you answered no to any of these questions, instantiate a configuration object and read on: $config = HTMLPurifier_Config::createDefault(); 4.1. Setting a different character encoding You really shouldn't use any other encoding except UTF-8, especially if you plan to support multilingual websites (read section three for more details). However, switching to UTF-8 is not always immediately feasible, so we can adapt. HTML Purifier uses iconv to support other character encodings, as such, any encoding that iconv supports HTML Purifier supports with this code: $config->set('Core.Encoding', /* put your encoding here */); An example usage for Latin-1 websites (the most common encoding for English websites): $config->set('Core.Encoding', 'ISO-8859-1'); Note that HTML Purifier's support for non-Unicode encodings is crippled by the fact that any character not supported by that encoding will be silently dropped, EVEN if it is ampersand escaped. If you want to work around this, you are welcome to read docs/enduser-utf8.html for a fix, but please be cognizant of the issues the "solution" creates (for this reason, I do not include the solution in this document). 4.2. Setting a different doctype For those of you using HTML 4.01 Transitional, you can disable XHTML output like this: $config->set('HTML.Doctype', 'HTML 4.01 Transitional'); Other supported doctypes include: * HTML 4.01 Strict * HTML 4.01 Transitional * XHTML 1.0 Strict * XHTML 1.0 Transitional * XHTML 1.1 4.3. Other settings There are more configuration directives which can be read about here: They're a bit boring, but they can help out for those of you who like to exert maximum control over your code. Some of the more interesting ones are configurable at the demo and are well worth looking into for your own system. For example, you can fine tune allowed elements and attributes, convert relative URLs to absolute ones, and even autoparagraph input text! These are, respectively, %HTML.Allowed, %URI.MakeAbsolute and %URI.Base, and %AutoFormat.AutoParagraph. The %Namespace.Directive naming convention translates to: $config->set('Namespace.Directive', $value); E.g. $config->set('HTML.Allowed', 'p,b,a[href],i'); $config->set('URI.Base', 'http://www.example.com'); $config->set('URI.MakeAbsolute', true); $config->set('AutoFormat.AutoParagraph', true); --------------------------------------------------------------------------- 5. Caching HTML Purifier generates some cache files (generally one or two) to speed up its execution. For maximum performance, make sure that library/HTMLPurifier/DefinitionCache/Serializer is writeable by the webserver. If you are in the library/ folder of HTML Purifier, you can set the appropriate permissions using: chmod -R 0755 HTMLPurifier/DefinitionCache/Serializer If the above command doesn't work, you may need to assign write permissions to all. This may be necessary if your webserver runs as nobody, but is not recommended since it means any other user can write files in the directory. Use: chmod -R 0777 HTMLPurifier/DefinitionCache/Serializer You can also chmod files via your FTP client; this option is usually accessible by right clicking the corresponding directory and then selecting "chmod" or "file permissions". Starting with 2.0.1, HTML Purifier will generate friendly error messages that will tell you exactly what you have to chmod the directory to, if in doubt, follow its advice. If you are unable or unwilling to give write permissions to the cache directory, you can either disable the cache (and suffer a performance hit): $config->set('Core.DefinitionCache', null); Or move the cache directory somewhere else (no trailing slash): $config->set('Cache.SerializerPath', '/home/user/absolute/path'); --------------------------------------------------------------------------- 6. Using the code The interface is mind-numbingly simple: $purifier = new HTMLPurifier($config); $clean_html = $purifier->purify( $dirty_html ); That's it! For more examples, check out docs/examples/ (they aren't very different though). Also, docs/enduser-slow.html gives advice on what to do if HTML Purifier is slowing down your application. --------------------------------------------------------------------------- 7. Quick install First, make sure library/HTMLPurifier/DefinitionCache/Serializer is writable by the webserver (see Section 5: Caching above for details). If your website is in UTF-8 and XHTML Transitional, use this code: purify($dirty_html); ?> If your website is in a different encoding or doctype, use this code: set('Core.Encoding', 'ISO-8859-1'); // replace with your encoding $config->set('HTML.Doctype', 'HTML 4.01 Transitional'); // replace with your doctype $purifier = new HTMLPurifier($config); $clean_html = $purifier->purify($dirty_html); ?> vim: et sw=4 sts=4 php-htmlpurifier-4.4.0+dfsg1/INSTALL.fr.utf8010064400000000000000000000037701170566125200153050ustar00 Installation Comment installer HTML Purifier Attention: Ce document a encode en UTF-8.

Les extensions optionnel est iconv (en général déjà installer) et tidy (répandu aussi). Si vous utilisez UTF-8 et ne voulez pas l'indentation, vous pouvez utiliser HTML Purifier sans ces extensions. 2. Inclure la librarie Utilisez: require_once '/path/to/library/HTMLPurifier.auto.php'; ...quand vous devez utiliser HTML Purifier (ne inclure pas quand vous ne devez pas, parce que HTML Purifier est trés grand.) HTML Purifier utilise 'autoload'. Si vous avez définu la fonction __autoload, vous doivez ajoute cet programme: spl_autoload_register('__autoload') Plus d'information est dans le document 'INSTALL'. 3. Installation vite Si votre site web est en UTF-8 et XHTML Transitional, utilisez: purify($html_salle); ?> Sinon, utilisez: set('Core', 'Encoding', 'ISO-8859-1'); //remplacez avec votre encoding $config->set('Core', 'XHTML', true); //remplacez avec false si HTML 4.01 $purificateur = new HTMLPurifier($config); $html_propre = $purificateur->purify($html_salle); ?> vim: et sw=4 sts=4 php-htmlpurifier-4.4.0+dfsg1/LICENSE010064400000000000000000000635301170566125200137660ustar00 GNU LESSER GENERAL PUBLIC LICENSE Version 2.1, February 1999 Copyright (C) 1991, 1999 Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. [This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library Public License, version 2, hence the version number 2.1.] Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) The modified work must itself be a software library. b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Libraries If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public License as published by the Free Software Foundation; either version 2.1 of the License, or (at your option) any later version. This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU Lesser General Public License for more details. You should have received a copy of the GNU Lesser General Public License along with this library; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the library, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the library `Frob' (a library for tweaking knobs) written by James Random Hacker. , 1 April 1990 Ty Coon, President of Vice That's all there is to it! vim: et sw=4 sts=4 php-htmlpurifier-4.4.0+dfsg1/NEWS010064400000000000000000001554011170566125200134570ustar00NEWS ( CHANGELOG and HISTORY ) HTMLPurifier ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||| = KEY ==================== # Breaks back-compat ! Feature - Bugfix + Sub-comment . Internal change ========================== 4.4.0, released 2012-01-18 # Removed PEARSax3 handler. # URI.Munge now munges URIs inside the same host that go from https to http. Reported by Neike Taika-Tessaro. # Core.EscapeNonASCIICharacters now always transforms entities to entities, even if target encoding is UTF-8. # Tighten up selector validation in ExtractStyleBlocks. Non-syntactically valid selectors are now rejected, along with some of the more obscure ones such as attribute selectors, the :lang pseudoselector, and anything not in CSS2.1. Furthermore, ID and class selectors now work properly with the relevant configuration attributes. Also, mute errors when parsing CSS with CSS Tidy. ! Added support for 'scope' attribute on tables. ! Added %HTML.TargetBlank, which adds target="blank" to all outgoing links. ! Properly handle sub-lists directly nested inside of lists in a standards compliant way, by moving them into the preceding
  • ! Added %HTML.AllowedComments and %HTML.AllowedCommentsRegexp for limited allowed comments in untrusted situations. ! Implement iframes, and allow them to be used in untrusted mode with %HTML.SafeIframe and %URI.SafeIframeRegexp. Thanks Bradley M. Froehle for submitting an initial version of the patch. ! The Forms module now works properly for transitional doctypes. ! Added support for internationalized domain names. You need the PEAR Net_IDNA2 module to be in your path; if it is installed, ensure the class can be loaded and then set %Core.EnableIDNA to true. - Color keywords are now case insensitive. Thanks Yzmir Ramirez for reporting. - Explicitly initialize anonModule variable to null. - Do not duplicate nofollow if already present. Thanks 178 for reporting. - Do not add nofollow if hostname matches our current host. Thanks 178 for reporting, and Neike Taika-Tessaro for helping diagnose. - Do not unset parser variable; this fixes intermittent serialization problems. Thanks Neike Taika-Tessaro for reporting, bill <10010tiger@gmail.com> for diagnosing. - Fix iconv truncation bug, where non-UTF-8 target encodings see output truncated after around 8000 characters. Thanks Jörg Ludwig for reporting. - Fix broken table content model for XHTML1.1 (and also earlier versions, although the W3C validator doesn't catch those violations). Thanks GlitchMr for reporting. 4.3.0, released 2011-03-27 # Fixed broken caching of customized raw definitions, but requires an API change. The old API still works but will emit a warning, see http://htmlpurifier.org/docs/enduser-customize.html#optimized for how to upgrade your code. # Protect against Internet Explorer innerHTML behavior by specially treating attributes with backticks but no angled brackets, quotes or spaces. This constitutes a slight semantic change, which can be reverted using %Output.FixInnerHTML. Reported by Neike Taika-Tessaro and Mario Heiderich. # Protect against cssText/innerHTML by restricting allowed characters used in fonts further than mandated by the specification and encoding some extra special characters in URLs. Reported by Neike Taika-Tessaro and Mario Heiderich. ! Added %HTML.Nofollow to add rel="nofollow" to external links. ! More types of SPL autoloaders allowed on later versions of PHP. ! Implementations for position, top, left, right, bottom, z-index when %CSS.Trusted is on. ! Add %Cache.SerializerPermissions option for custom serializer directory/file permissions ! Fix longstanding bug in Flash support for non-IE browsers, and allow more wmode attributes. ! Add %CSS.AllowedFonts to restrict permissible font names. - Switch to an iterative traversal of the DOM, which prevents us from running out of stack space for deeply nested documents. Thanks Maxim Krizhanovsky for contributing a patch. - Make removal of conditional IE comments ungreedy; thanks Bernd for reporting. - Escape CDATA before removing Internet Explorer comments. - Fix removal of id attributes under certain conditions by ensuring armor attributes are preserved when recreating tags. - Check if schema.ser was corrupted. - Check if zend.ze1_compatibility_mode is on, and error out if it is. This safety check is only done for HTMLPurifier.auto.php; if you are using standalone or the specialized includes files, you're expected to know what you're doing. - Stop repeatedly writing the cache file after I'm done customizing a raw definition. Reported by ajh. - Switch to using require_once in the Bootstrap to work around bad interaction with Zend Debugger and APC. Reported by Antonio Parraga. - Fix URI handling when hostname is missing but scheme is present.

      1. tag. - Always quote the insides of url(...) in CSS. 4.0.0, released 2009-07-07 # APIs for ConfigSchema subsystem have substantially changed. See docs/dev-config-bcbreaks.txt for details; in essence, anything that had both namespace and directive now have a single unified key. # Some configuration directives were renamed, specifically: %AutoFormatParam.PurifierLinkifyDocURL -> %AutoFormat.PurifierLinkify.DocURL %FilterParam.ExtractStyleBlocksEscaping -> %Filter.ExtractStyleBlocks.Escaping %FilterParam.ExtractStyleBlocksScope -> %Filter.ExtractStyleBlocks.Scope %FilterParam.ExtractStyleBlocksTidyImpl -> %Filter.ExtractStyleBlocks.TidyImpl As usual, the old directive names will still work, but will throw E_NOTICE errors. # The allowed values for class have been relaxed to allow all of CDATA for doctypes that are not XHTML 1.1 or XHTML 2.0. For old behavior, set %Attr.ClassUseCDATA to false. # Instead of appending the content model to an old content model, a blank element will replace the old content model. You can use #SUPER to get the old content model. ! More robust support for name="" and id="" ! HTMLPurifier_Config::inherit($config) allows you to inherit one configuration, and have changes to that configuration be propagated to all of its children. ! Implement %HTML.Attr.Name.UseCDATA, which relaxes validation rules on the name attribute when set. Use with care. Thanks Ian Cook for sponsoring. ! Implement %AutoFormat.RemoveEmpty.RemoveNbsp, which removes empty tags that contain non-breaking spaces as well other whitespace. You can also modify which tags should have   maintained with %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions. ! Implement %Attr.AllowedClasses, which allows administrators to restrict classes users can use to a specified finite set of classes, and %Attr.ForbiddenClasses, which is the logical inverse. ! You can now maintain your own configuration schema directories by creating a config-schema.php file or passing an extra argument. Check docs/dev-config-schema.html for more details. ! Added HTMLPurifier_Config->serialize() method, which lets you save away your configuration in a compact serial file, which you can unserialize and use directly without having to go through the overhead of setup. - Fix bug where URIDefinition would not get cleared if it's directives got changed. - Fix fatal error in HTMLPurifier_Encoder on certain platforms (probably NetBSD 5.0) - Fix bug in Linkify autoformatter involving http://foo - Make %URI.Munge not apply to links that have the same host as your host. - Prevent stray tag from truncating output, if a second is present. . Created script maintenance/rename-config.php for renaming a configuration directive while maintaining its alias. This script does not change source code. . Implement namespace locking for definition construction, to prevent bugs where a directive is used for definition construction but is not used to construct the cache hash. 3.3.0, released 2009-02-16 ! Implement CSS property 'overflow' when %CSS.AllowTricky is true. ! Implement generic property list classess - Fix bug with testEncodingSupportsASCII() algorithm when iconv() implementation does not do the "right thing" with characters not supported in the output set. - Spellcheck UTF-8: The Secret To Character Encoding - Fix improper removal of the contents of elements with only whitespace. Thanks Eric Wald for reporting. - Fix broken test suite in versions of PHP without spl_autoload_register() - Fix degenerate case with YouTube filter involving double hyphens. Thanks Pierre Attar for reporting. - Fix YouTube rendering problem on certain versions of Firefox. - Fix CSSDefinition Printer problems with decorators - Add text parameter to unit tests, forces text output . Add verbose mode to command line test runner, use (--verbose) . Turn on unit tests for UnitConverter . Fix missing version number in configuration %Attr.DefaultImageAlt (added 3.2.0) . Fix newline errors that caused spurious failures when CRLF HTML Purifier was tested on Linux. . Removed trailing whitespace from all text files, see remote-trailing-whitespace.php maintenance script. . Convert configuration to use property list backend. 3.2.0, released 2008-10-31 # Using %Core.CollectErrors forces line number/column tracking on, whereas previously you could theoretically turn it off. # HTMLPurifier_Injector->notifyEnd() is formally deprecated. Please use handleEnd() instead. ! %Output.AttrSort for when you need your attributes in alphabetical order to deal with a bug in FCKEditor. Requested by frank farmer. ! Enable HTML comments when %HTML.Trusted is on. Requested by Waldo Jaquith. ! Proper support for name attribute. It is now allowed and equivalent to the id attribute in a and img tags, and is only converted to id when %HTML.TidyLevel is heavy (for all doctypes). ! %AutoFormat.RemoveEmpty to remove some empty tags from documents. Please don't use on hand-written HTML. ! Add error-cases for unsupported elements in MakeWellFormed. This enables the strategy to be used, standalone, on untrusted input. ! %Core.AggressivelyFixLt is on by default. This causes more sensible processing of left angled brackets in smileys and other whatnot. ! Test scripts now have a 'type' parameter, which lets you say 'htmlpurifier', 'phpt', 'vtest', etc. in order to only execute those tests. This supercedes the --only-phpt parameter, although for backwards-compatibility the flag will still work. ! AutoParagraph auto-formatter will now preserve double-newlines upon output. Users who are not performing inbound filtering, this may seem a little useless, but as a bonus, the test suite and handling of edge cases is also improved. ! Experimental implementation of forms for %HTML.Trusted ! Track column numbers when maintain line numbers is on ! Proprietary 'background' attribute on table-related elements converted into corresponding CSS. Thanks Fusemail for sponsoring this feature! ! Add forward(), forwardUntilEndToken(), backward() and current() to Injector supertype. ! HTMLPurifier_Injector->handleEnd() permits modification to end tokens. The time of operation varies slightly from notifyEnd() as *all* end tokens are processed by the injector before they are subject to the well-formedness rules. ! %Attr.DefaultImageAlt allows overriding default behavior of setting alt to basename of image when not present. ! %AutoFormat.DisplayLinkURI neuters tags into plain text URLs. - Fix two bugs in %URI.MakeAbsolute; one involving empty paths in base URLs, the other involving an undefined $is_folder error. - Throw error when %Core.Encoding is set to a spurious value. Previously, this errored silently and returned false. - Redirected stderr to stdout for flush error output. - %URI.DisableExternal will now use the host in %URI.Base if %URI.Host is not available. - Do not re-munge URL if the output URL has the same host as the input URL. Requested by Chris. - Fix error in documentation regarding %Filter.ExtractStyleBlocks - Prevent ]]> from triggering %Core.ConvertDocumentToFragment - Fix bug with inline elements in blockquotes conflicting with strict doctype - Detect if HTML support is disabled for DOM by checking for loadHTML() method. - Fix bug where dots and double-dots in absolute URLs without hostname were not collapsed by URIFilter_MakeAbsolute. - Fix bug with anonymous modules operating on SafeEmbed or SafeObject elements by reordering their addition. - Will now throw exception on many error conditions during lexer creation; also throw an exception when MaintainLineNumbers is true, but a non-tracksLineNumbers is being used. - Detect if domxml extension is loaded, and use DirectLEx accordingly. - Improve handling of big numbers with floating point arithmetic in UnitConverter. Reported by David Morton. . Strategy_MakeWellFormed now operates in-place, saving memory and allowing for more interesting filter-backtracking . New HTMLPurifier_Injector->rewind() functionality, allows injectors to rewind index to reprocess tokens. . StringHashParser now allows for multiline sections with "empty" content; previously the section would remain undefined. . Added --quick option to multitest.php, which tests only the most recent release for each series. . Added --distro option to multitest.php, which accepts either 'normal' or 'standalone'. This supercedes --exclude-normal and --exclude-standalone 3.1.1, released 2008-06-19 # %URI.Munge now, by default, does not munge resources (for example, ) In order to enable this again, please set %URI.MungeResources to true. ! More robust imagecrash protection with height/width CSS with %CSS.MaxImgLength, and height/width HTML with %HTML.MaxImgLength. ! %URI.MungeSecretKey for secure URI munging. Thanks Chris for sponsoring this feature. Check out the corresponding documentation for details. (Att Nightly testers: The API for this feature changed before the general release. Namely, rename your directives %URI.SecureMungeSecretKey => %URI.MungeSecretKey and and %URI.SecureMunge => %URI.Munge) ! Implemented post URI filtering. Set member variable $post to true to set a URIFilter as such. ! Allow modules to define injectors via $info_injector. Injectors are automatically disabled if injector's needed elements are not found. ! Support for "safe" objects added, use %HTML.SafeObject and %HTML.SafeEmbed. Thanks Chris for sponsoring. If you've been using ad hoc code from the forums, PLEASE use this instead. ! Added substitutions for %e, %n, %a and %p in %URI.Munge (in order, embedded, tag name, attribute name, CSS property name). See %URI.Munge for more details. Requested by Jochem Blok. - Disable percent height/width attributes for img. - AttrValidator operations are now atomic; updates to attributes are not manifest in token until end of operations. This prevents naughty internal code from directly modifying CurrentToken when they're not supposed to. This semantics change was requested by frank farmer. - Percent encoding checks enabled for URI query and fragment - Fix stray backslashes in font-family; CSS Unicode character escapes are now properly resolved (although *only* in font-family). Thanks Takeshi Terada for reporting. - Improve parseCDATA algorithm to take into account newline normalization - Account for browser confusion between Yen character and backslash in Shift_JIS encoding. This fix generalizes to any other encoding which is not a strict superset of printable ASCII. Thanks Takeshi Terada for reporting. - Fix missing configuration parameter in Generator calls. Thanks vs for the partial patch. - Improved adherence to Unicode by checking for non-character codepoints. Thanks Geoffrey Sneddon for reporting. This may result in degraded performance for extremely large inputs. - Allow CSS property-value pair ''text-decoration: none''. Thanks Jochem Blok for reporting. . Added HTMLPurifier_UnitConverter and HTMLPurifier_Length for convenient handling of CSS-style lengths. HTMLPurifier_AttrDef_CSS_Length now uses this class. . API of HTMLPurifier_AttrDef_CSS_Length changed from __construct($disable_negative) to __construct($min, $max). __construct(true) is equivalent to __construct('0'). . Added HTMLPurifier_AttrDef_Switch class . Rename HTMLPurifier_HTMLModule_Tidy->construct() to setup() and bubble method up inheritance hierarchy to HTMLPurifier_HTMLModule. All HTMLModules get this called with the configuration object. All modules now use this rather than __construct(), although legacy code using constructors will still work--the new format, however, lets modules access the configuration object for HTML namespace dependant tweaks. . AttrDef_HTML_Pixels now takes a single construction parameter, pixels. . ConfigSchema data-structure heavily optimized; on average it uses a third the memory it did previously. The interface has changed accordingly, consult changes to HTMLPurifier_Config for details. . Variable parsing types now are magic integers instead of strings . Added benchmark for ConfigSchema . HTMLPurifier_Generator requires $config and $context parameters. If you don't know what they should be, use HTMLPurifier_Config::createDefault() and new HTMLPurifier_Context(). . Printers now properly distinguish between output configuration, and target configuration. This is not applicable to scripts using the Printers for HTML Purifier related tasks. . HTML/CSS Printers must be primed with prepareGenerator($gen_config), otherwise fatal errors will ensue. . URIFilter->prepare can return false in order to abort loading of the filter . Factory for AttrDef_URI implemented, URI#embedded to indicate URI that embeds an external resource. . %URI.Munge functionality factored out into a post-filter class. . Added CurrentCSSProperty context variable during CSS validation 3.1.0, released 2008-05-18 # Unnecessary references to objects (vestiges of PHP4) removed from method signatures. The following methods do not need references when assigning from them and will result in E_STRICT errors if you try: + HTMLPurifier_Config->get*Definition() [* = HTML, CSS] + HTMLPurifier_ConfigSchema::instance() + HTMLPurifier_DefinitionCacheFactory::instance() + HTMLPurifier_DefinitionCacheFactory->create() + HTMLPurifier_DoctypeRegistry->register() + HTMLPurifier_DoctypeRegistry->get() + HTMLPurifier_HTMLModule->addElement() + HTMLPurifier_HTMLModule->addBlankElement() + HTMLPurifier_LanguageFactory::instance() # Printer_ConfigForm's get*() functions were static-ified # %HTML.ForbiddenAttributes requires attribute declarations to be in the form of tag@attr, NOT tag.attr (which will throw an error and won't do anything). This is for forwards compatibility with XML; you'd do best to migrate an %HTML.AllowedAttributes directives to this syntax too. ! Allow index to be false for config from form creation ! Added HTMLPurifier::VERSION constant ! Commas, not dashes, used for serializer IDs. This change is forwards-compatible and allows for version numbers like "3.1.0-dev". ! %HTML.Allowed deals gracefully with whitespace anywhere, anytime! ! HTML Purifier's URI handling is a lot more robust, with much stricter validation checks and better percent encoding handling. Thanks Gareth Heyes for indicating security vulnerabilities from lax percent encoding. ! Bootstrap autoloader deals more robustly with classes that don't exist, preventing class_exists($class, true) from barfing. - InterchangeBuilder now alphabetizes its lists - Validation error in configdoc output fixed - Iconv and other encoding errors muted even with custom error handlers that do not honor error_reporting - Add protection against imagecrash attack with CSS height/width - HTMLPurifier::instance() created for consistency, is equivalent to getInstance() - Fixed and revamped broken ConfigForm smoketest - Bug with bool/null fields in Printer_ConfigForm fixed - Bug with global forbidden attributes fixed - Improved error messages for allowed and forbidden HTML elements and attributes - Missing (or null) in configdoc documentation restored - If DOM throws and exception during parsing with PH5P (occurs in newer versions of DOM), HTML Purifier punts to DirectLex - Fatal error with unserialization of ScriptRequired - Created directories are now chmod'ed properly - Fixed bug with fallback languages in LanguageFactory - Standalone testing setup properly with autoload . Out-of-date documentation revised . UTF-8 encoding check optimization as suggested by Diego . HTMLPurifier_Error removed in favor of exceptions . More copy() function removed; should use clone instead . More extensive unit tests for HTMLDefinition . assertPurification moved to central harness . HTMLPurifier_Generator accepts $config and $context parameters during instantiation, not runtime . Double-quotes outside of attribute values are now unescaped 3.1.0rc1, released 2008-04-22 # Autoload support added. Internal require_once's removed in favor of an explicit require list or autoloading. To use HTML Purifier, you must now either use HTMLPurifier.auto.php or HTMLPurifier.includes.php; setting the include path and including HTMLPurifier.php is insufficient--in such cases include HTMLPurifier.autoload.php as well to register our autoload handler (or modify your autoload function to check HTMLPurifier_Bootstrap::getPath($class)). You can also use HTMLPurifier.safe-includes.php for a less performance friendly but more user-friendly library load. # HTMLPurifier_ConfigSchema static functions are officially deprecated. Schema information is stored in the ConfigSchema directory, and the maintenance/generate-schema-cache.php generates the schema.ser file, which is now instantiated. Support for userland schema changes coming soon! # HTMLPurifier_Config will now throw E_USER_NOTICE when you use a directive alias; to get rid of these errors just modify your configuration to use the new directive name. # HTMLPurifier->addFilter is deprecated; built-in filters can now be enabled using %Filter.$filter_name or by setting your own filters using %Filter.Custom # Directive-level safety properties superceded in favor of module-level safety. Internal method HTMLModule->addElement() has changed, although the externally visible HTMLDefinition->addElement has *not* changed. ! Extra utility classes for testing and non-library operations can be found in extras/. Specifically, these are FSTools and ConfigDoc. You may find a use for these in your own project, but right now they are highly experimental and volatile. ! Integration with PHPT allows for automated smoketests ! Limited support for proprietary HTML elements, namely , sponsored by Chris. You can enable them with %HTML.Proprietary if your client demands them. ! Support for !important CSS cascade modifier. By default, this will be stripped from CSS, but you can enable it using %CSS.AllowImportant ! Support for display and visibility CSS properties added, set %CSS.AllowTricky to true to use them. ! HTML Purifier now has its own Exception hierarchy under HTMLPurifier_Exception. Developer error (not enduser error) can cause these to be triggered. ! Experimental kses() wrapper introduced with HTMLPurifier.kses.php ! Finally %CSS.AllowedProperties for tweaking allowed CSS properties without mucking around with HTMLPurifier_CSSDefinition ! ConfigDoc output has been enhanced with version and deprecation info. ! %HTML.ForbiddenAttributes and %HTML.ForbiddenElements implemented. - Autoclose now operates iteratively, i.e.
        now has both span tags closed. - Various HTMLPurifier_Config convenience functions now accept another parameter $schema which defines what HTMLPurifier_ConfigSchema to use besides the global default. - Fix bug with trusted script handling in libxml versions later than 2.6.28. - Fix bug in ExtractStyleBlocks with comments in style tags - Fix bug in comment parsing for DirectLex - Flush output now displayed when in command line mode for unit tester - Fix bug with rgb(0, 1, 2) color syntax with spaces inside shorthand syntax - HTMLPurifier_HTMLDefinition->addAttribute can now be called multiple times on the same element without emitting errors. - Fixed fatal error in PH5P lexer with invalid tag names . Plugins now get their own changelogs according to project conventions. . Convert tokens to use instanceof, reducing memory footprint and improving comparison speed. . Dry runs now supported in SimpleTest; testing facilities improved . Bootstrap class added for handling autoloading functionality . Implemented recursive glob at FSTools->globr . ConfigSchema now has instance methods for all corresponding define* static methods. . A couple of new historical maintenance scripts were added. . HTMLPurifier/HTMLModule/Tidy/XHTMLAndHTML4.php split into two files . tests/index.php can now be run from any directory. . HTMLPurifier_Token subclasses split into seperate files . HTMLPURIFIER_PREFIX now is defined in Bootstrap.php, NOT HTMLPurifier.php . HTMLPURIFIER_PREFIX can now be defined outside of HTML Purifier . New --php=php flag added, allows PHP executable to be specified (command line only!) . htmlpurifier_add_test() preferred method to translate test files in to classes, because it handles PHPT files too. . Debugger class is deprecated and will be removed soon. . Command line argument parsing for testing scripts revamped, now --opt value format is supported. . Smoketests now cleanup after magic quotes . Generator now can output comments (however, comments are still stripped from HTML Purifier output) . HTMLPurifier_ConfigSchema->validate() deprecated in favor of HTMLPurifier_VarParser->parse() . Integers auto-cast into float type by VarParser. . HTMLPURIFIER_STRICT removed; no validation is performed on runtime, only during cache generation . Reordered script calls in maintenance/flush.php . Command line scripts now honor exit codes . When --flush fails in unit testers, abort tests and print message . Improved documentation in docs/dev-flush.html about the maintenance scripts . copy() methods removed in favor of clone keyword 3.0.0, released 2008-01-06 # HTML Purifier is PHP 5 only! The 2.1.x branch will be maintained until PHP 4 is completely deprecated, but no new features will be added to it. + Visibility declarations added + Constructor methods renamed to __construct() + PHP4 reference cruft removed (in progress) ! CSS properties are now case-insensitive ! DefinitionCacheFactory now can register new implementations ! New HTMLPurifier_Filter_ExtractStyleBlocks for extracting

        HTML Purifier is a Swiss-Army Knife

        HTML Purifier End-User Documentation

        HTML Purifier has this quirk where if you try to allow certain elements or attributes, HTML Purifier will tell you that it's not supported, and that you should go to the forums to find out how to implement it. Well, this document is how to implement elements and attributes which HTML Purifier doesn't support out of the box.

        Is it necessary?

        Before we even write any code, it is paramount to consider whether or not the code we're writing is necessary or not. HTML Purifier, by default, contains a large set of elements and attributes: large enough so that any element or attribute in XHTML 1.0 or 1.1 (and its HTML variants) that can be safely used by the general public is implemented.

        So what needs to be implemented? (Feel free to skip this section if you know what you want).

        XHTML 1.0

        All of the modules listed below are based off of the modularization of XHTML, which, while technically for XHTML 1.1, is quite a useful resource.

        • Structure
        • Frames
        • Applets (deprecated)
        • Forms
        • Image maps

        If you don't recognize it, you probably don't need it. But the curious can look all of these modules up in the above-mentioned document. Note that inline scripting comes packaged with HTML Purifier (more on this later).

        XHTML 1.1

        As of HTMLPurifier 2.1.0, we have implemented the Ruby module, which defines a set of tags for publishing short annotations for text, used mostly in Japanese and Chinese school texts, but applicable for positioning any text (not limited to translations) above or below other corresponding text.

        HTML 5

        HTML 5 is a fork of HTML 4.01 by WHATWG, who believed that XHTML 2.0 was headed in the wrong direction. It too is a working draft, and may change drastically before publication, but it should be noted that the canvas tag has been implemented by many browser vendors.

        Proprietary

        There are a number of proprietary tags still in the wild. Many of them have been documented in ref-proprietary-tags.txt, but there is currently no implementation for any of them.

        Extensions

        There are also a number of other XML languages out there that can be embedded in HTML documents: two of the most popular are MathML and SVG, and I frequently get requests to implement these. But they are expansive, comprehensive specifications, and it would take far too long to implement them correctly (most systems I've seen go as far as whitelisting tags and no further; come on, what about nesting!)

        Word of warning: HTML Purifier is currently not namespace aware.

        Giving back

        As you may imagine from the details above (don't be abashed if you didn't read it all: a glance over would have done), there's quite a bit that HTML Purifier doesn't implement. Recent architectural changes have allowed HTML Purifier to implement elements and attributes that are not safe! Don't worry, they won't be activated unless you set %HTML.Trusted to true, but they certainly help out users who need to put, say, forms on their page and don't want to go through the trouble of reading this and implementing it themself.

        So any of the above that you implement for your own application could help out some other poor sap on the other side of the globe. Help us out, and send back code so that it can be hammered into a module and released with the core. Any code would be greatly appreciated!

        And now...

        Enough philosophical talk, time for some code:

        $config = HTMLPurifier_Config::createDefault();
        $config->set('HTML.DefinitionID', 'enduser-customize.html tutorial');
        $config->set('HTML.DefinitionRev', 1);
        if ($def = $config->maybeGetRawHTMLDefinition()) {
            // our code will go here
        }

        Assuming that HTML Purifier has already been properly loaded (hint: include HTMLPurifier.auto.php), this code will set up the environment that you need to start customizing the HTML definition. What's going on?

        • The first three lines are regular configuration code:
          • %HTML.DefinitionID is set to a unique identifier for your custom HTML definition. This prevents it from clobbering other custom definitions on the same installation.
          • %HTML.DefinitionRev is a revision integer of your HTML definition. Because HTML definitions are cached, you'll need to increment this whenever you make a change in order to flush the cache.
        • The fourth line retrieves a raw HTMLPurifier_HTMLDefinition object that we will be tweaking. Interestingly enough, we have placed it in an if block: this is because maybeGetRawHTMLDefinition, as its name suggests, may return a NULL, in which case we should skip doing any initialization. This, in fact, will correspond to when our fully customized object is already in the cache.

        Turn off caching

        To make development easier, we're going to temporarily turn off definition caching:

        $config = HTMLPurifier_Config::createDefault();
        $config->set('HTML.DefinitionID', 'enduser-customize.html tutorial');
        $config->set('HTML.DefinitionRev', 1);
        $config->set('Cache.DefinitionImpl', null); // TODO: remove this later!
        $def = $config->getHTMLDefinition(true);

        A few things should be mentioned about the caching mechanism before we move on. For performance reasons, HTML Purifier caches generated HTMLPurifier_Definition objects in serialized files stored (by default) in library/HTMLPurifier/DefinitionCache/Serializer. A lot of processing is done in order to create these objects, so it makes little sense to repeat the same processing over and over again whenever HTML Purifier is called.

        In order to identify a cache entry, HTML Purifier uses three variables: the library's version number, the value of %HTML.DefinitionRev and a serial of relevant configuration. Whenever any of these changes, a new HTML definition is generated. Notice that there is no way for the definition object to track changes to customizations: here, it is up to you to supply appropriate information to DefinitionID and DefinitionRev.

        Add an attribute

        For this example, we're going to implement the target attribute found on a elements. To implement an attribute, we have to ask a few questions:

        1. What element is it found on?
        2. What is its name?
        3. Is it required or optional?
        4. What are valid values for it?

        The first three are easy: the element is a, the attribute is target, and it is not a required attribute. (If it was required, we'd need to append an asterisk to the attribute name, you'll see an example of this in the addElement() example).

        The last question is a little trickier. Lets allow the special values: _blank, _self, _target and _top. The form of this is called an enumeration, a list of valid values, although only one can be used at a time. To translate this into code form, we write:

        $config = HTMLPurifier_Config::createDefault();
        $config->set('HTML.DefinitionID', 'enduser-customize.html tutorial');
        $config->set('HTML.DefinitionRev', 1);
        $config->set('Cache.DefinitionImpl', null); // remove this later!
        $def = $config->getHTMLDefinition(true);
        $def->addAttribute('a', 'target', 'Enum#_blank,_self,_target,_top');

        The Enum#_blank,_self,_target,_top does all the magic. The string is split into two parts, separated by a hash mark (#):

        1. The first part is the name of what we call an AttrDef
        2. The second part is the parameter of the above-mentioned AttrDef

        If that sounds vague and generic, it's because it is! HTML Purifier defines an assortment of different attribute types one can use, and each of these has their own specialized parameter format. Here are some of the more useful ones:

        Type Format Description
        Enum [s:]value1,value2,... Attribute with a number of valid values, one of which may be used. When s: is present, the enumeration is case sensitive.
        Bool attribute_name Boolean attribute, with only one valid value: the name of the attribute.
        CDATA Attribute of arbitrary text. Can also be referred to as Text (the specification makes a semantic distinction between the two).
        ID Attribute that specifies a unique ID
        Pixels Attribute that specifies an integer pixel length
        Length Attribute that specifies a pixel or percentage length
        NMTOKENS Attribute that specifies a number of name tokens, example: the class attribute
        URI Attribute that specifies a URI, example: the href attribute
        Number Attribute that specifies an positive integer number

        For a complete list, consult library/HTMLPurifier/AttrTypes.php; more information on attributes that accept parameters can be found on their respective includes in library/HTMLPurifier/AttrDef.

        Sometimes, the restrictive list in AttrTypes just doesn't cut it. Don't sweat: you can also use a fully instantiated object as the value. The equivalent, verbose form of the above example is:

        $config = HTMLPurifier_Config::createDefault();
        $config->set('HTML.DefinitionID', 'enduser-customize.html tutorial');
        $config->set('HTML.DefinitionRev', 1);
        $config->set('Cache.DefinitionImpl', null); // remove this later!
        $def = $config->getHTMLDefinition(true);
        $def->addAttribute('a', 'target', new HTMLPurifier_AttrDef_Enum(
          array('_blank','_self','_target','_top')
        ));

        Trust me, you'll learn to love the shorthand.

        Add an element

        Adding attributes is really small-fry stuff, though, and it was possible to add them (albeit a bit more wordy) prior to 2.0. The real gem of the Advanced API is adding elements. There are five questions to ask when adding a new element:

        1. What is the element's name?
        2. What content set does this element belong to?
        3. What are the allowed children of this element?
        4. What attributes does the element allow that are general?
        5. What attributes does the element allow that are specific to this element?

        It's a mouthful, and you'll be slightly lost if your not familiar with the HTML specification, so let's explain them step by step.

        Content set

        The HTML specification defines two major content sets: Inline and Block. Each of these content sets contain a list of elements: Inline contains things like span and b while Block contains things like div and blockquote.

        These content sets amount to a macro mechanism for HTML definition. Most elements in HTML are organized into one of these two sets, and most elements in HTML allow elements from one of these sets. If we had to write each element verbatim into each other element's allowed children, we would have ridiculously large lists; instead we use content sets to compactify the declaration.

        Practically speaking, there are several useful values you can use here:

        Content set Description
        Inline Character level elements, text
        Block Block-like elements, like paragraphs and lists
        false Any element that doesn't fit into the mold, for example li or tr

        By specifying a valid value here, all other elements that use that content set will also allow your element, without you having to do anything. If you specify false, you'll have to register your element manually.

        Allowed children

        Allowed children defines the elements that this element can contain. The allowed values may range from none to a complex regexp depending on your element.

        If you've ever taken a look at the HTML DTD's before, you may have noticed declarations like this:

        <!ELEMENT LI - O (%flow;)*             -- list item -->

        The (%flow;)* indicates the allowed children of the li tag: li allows any number of flow elements as its children. (The - O allows the closing tag to be omitted, though in XML this is not allowed.) In HTML Purifier, we'd write it like Flow (here's where the content sets we were discussing earlier come into play). There are three shorthand content models you can specify:

        Content model Description
        Empty No children allowed, like br or hr
        Inline Any number of inline elements and text, like span
        Flow Any number of inline elements, block elements and text, like div

        This covers 90% of all the cases out there, but what about elements that break the mold like ul? This guy requires at least one child, and the only valid children for it are li. The content model is: Required: li. There are two parts: the first type determines what ChildDef will be used to validate content models. The most common values are:

        Type Description
        Required Children must be one or more of the valid elements
        Optional Children can be any number of the valid elements
        Custom Children must follow the DTD-style regex

        You can also implement your own ChildDef: this was done for a few special cases in HTML Purifier such as Chameleon (for ins and del), StrictBlockquote and Table.

        The second part specifies either valid elements or a regular expression. Valid elements are separated with horizontal bars (|), i.e. "a | b | c". Use #PCDATA to represent plain text. Regular expressions are based off of DTD's style:

        • Parentheses () are used for grouping
        • Commas (,) separate elements that should come one after another
        • Horizontal bars (|) indicate one or the other elements should be used
        • Plus signs (+) are used for a one or more match
        • Asterisks (*) are used for a zero or more match
        • Question marks (?) are used for a zero or one match

        For example, "a, b?, (c | d), e+, f*" means "In this order, one a element, at most one b element, one c or d element (but not both), one or more e elements, and any number of f elements." Regex veterans should be able to jump right in, and those not so savvy can always copy-paste W3C's content model definitions into HTML Purifier and hope for the best.

        A word of warning: while the regex format is extremely flexible on the developer's side, it is quite unforgiving on the user's side. If the user input does not exactly match the specification, the entire contents of the element will be nuked. This is why there is are specific content model types like Optional and Required: while they could be implemented as Custom: (valid | elements)*, the custom classes contain special recovery measures that make sure as much of the user's original content gets through. HTML Purifier's core, as a rule, does not use Custom.

        One final note: you can also use Content Sets inside your valid elements lists or regular expressions. In fact, the three shorthand content models mentioned above are just that: abbreviations:

        Content model Implementation
        Inline Optional: Inline | #PCDATA
        Flow Optional: Flow | #PCDATA

        When the definition is compiled, Inline will be replaced with a horizontal-bar separated list of inline elements. Also, notice that it does not contain text: you have to specify that yourself.

        Common attributes

        Congratulations: you have just gotten over the proverbial hump (Allowed children). Common attributes is much simpler, and boils down to one question: does your element have the id, style, class, title and lang attributes? If so, you'll want to specify the Common attribute collection, which contains these five attributes that are found on almost every HTML element in the specification.

        There are a few more collections, but they're really edge cases:

        Collection Attributes
        I18N lang, possibly xml:lang
        Core style, class, id and title

        Common is a combination of the above-mentioned collections.

        Readers familiar with the modularization may have noticed that the Core attribute collection differs from that specified by the abstract modules of the XHTML Modularization 1.1. We believe this section to be in error, as br permits the use of the style attribute even though it uses the Core collection, and the DTD and XML Schemas supplied by W3C support our interpretation.

        Attributes

        If you didn't read the earlier section on adding attributes, read it now. The last parameter is simply an array of attribute names to attribute implementations, in the exact same format as addAttribute().

        Putting it all together

        We're going to implement form. Before we embark, lets grab a reference implementation from over at the transitional DTD:

        <!ELEMENT FORM - - (%flow;)* -(FORM)   -- interactive form -->
        <!ATTLIST FORM
          %attrs;                              -- %coreattrs, %i18n, %events --
          action      %URI;          #REQUIRED -- server-side form handler --
          method      (GET|POST)     GET       -- HTTP method used to submit the form--
          enctype     %ContentType;  "application/x-www-form-urlencoded"
          accept      %ContentTypes; #IMPLIED  -- list of MIME types for file upload --
          name        CDATA          #IMPLIED  -- name of form for scripting --
          onsubmit    %Script;       #IMPLIED  -- the form was submitted --
          onreset     %Script;       #IMPLIED  -- the form was reset --
          target      %FrameTarget;  #IMPLIED  -- render in this frame --
          accept-charset %Charsets;  #IMPLIED  -- list of supported charsets --
          >

        Juicy! With just this, we can answer four of our five questions:

        1. What is the element's name? form
        2. What content set does this element belong to? Block (this needs a little sleuthing, I find the easiest way is to search the DTD for FORM and determine which set it is in.)
        3. What are the allowed children of this element? One or more flow elements, but no nested forms
        4. What attributes does the element allow that are general? Common
        5. What attributes does the element allow that are specific to this element? A whole bunch, see ATTLIST; we're going to do the vital ones: action, method and name

        Time for some code:

        $config = HTMLPurifier_Config::createDefault();
        $config->set('HTML.DefinitionID', 'enduser-customize.html tutorial');
        $config->set('HTML.DefinitionRev', 1);
        $config->set('Cache.DefinitionImpl', null); // remove this later!
        $def = $config->getHTMLDefinition(true);
        $def->addAttribute('a', 'target', new HTMLPurifier_AttrDef_Enum(
          array('_blank','_self','_target','_top')
        ));
        $form = $def->addElement(
          'form',   // name
          'Block',  // content set
          'Flow', // allowed children
          'Common', // attribute collection
          array( // attributes
            'action*' => 'URI',
            'method' => 'Enum#get|post',
            'name' => 'ID'
          )
        );
        $form->excludes = array('form' => true);

        Each of the parameters corresponds to one of the questions we asked. Notice that we added an asterisk to the end of the action attribute to indicate that it is required. If someone specifies a form without that attribute, the tag will be axed. Also, the extra line at the end is a special extra declaration that prevents forms from being nested within each other.

        And that's all there is to it! Implementing the rest of the form module is left as an exercise to the user; to see more examples check the library/HTMLPurifier/HTMLModule/ directory in your local HTML Purifier installation.

        And beyond...

        Perceptive users may have realized that, to a certain extent, we have simply re-implemented the facilities of XML Schema or the Document Type Definition. What you are seeing here, however, is not just an XML Schema or Document Type Definition: it is a fully expressive method of specifying the definition of HTML that is a portable superset of the capabilities of the two above-mentioned schema languages. What makes HTMLDefinition so powerful is the fact that if we don't have an implementation for a content model or an attribute definition, you can supply it yourself by writing a PHP class.

        There are many facets of HTMLDefinition beyond the Advanced API I have walked you through today. To find out more about these, you can check out these source files:

        Notes for HTML Purifier 4.2.0 and earlier

        Previously, this tutorial gave some incorrect template code for editing raw definitions, and that template code will now produce the error Due to a documentation error in previous version of HTML Purifier... Here is how to mechanically transform old-style code into new-style code.

        First, identify all code that edits the raw definition object, and put it together. Ensure none of this code must be run on every request; if some sub-part needs to always be run, move it outside this block. Here is an example below, with the raw definition object code bolded.

        $config = HTMLPurifier_Config::createDefault();
        $config->set('HTML.DefinitionID', 'enduser-customize.html tutorial');
        $config->set('HTML.DefinitionRev', 1);
        $def = $config->getHTMLDefinition(true);
        $def->addAttribute('a', 'target', 'Enum#_blank,_self,_target,_top');
        $purifier = new HTMLPurifier($config);

        Next, replace the raw definition retrieval with a maybeGetRawHTMLDefinition method call inside an if conditional, and place the editing code inside that if block.

        $config = HTMLPurifier_Config::createDefault();
        $config->set('HTML.DefinitionID', 'enduser-customize.html tutorial');
        $config->set('HTML.DefinitionRev', 1);
        if ($def = $config->maybeGetRawHTMLDefinition()) {
            $def->addAttribute('a', 'target', 'Enum#_blank,_self,_target,_top');
        }
        $purifier = new HTMLPurifier($config);

        And you're done! Alternatively, if you're OK with not ever caching your code, the following will still work and not emit warnings.

        $config = HTMLPurifier_Config::createDefault();
        $def = $config->getHTMLDefinition(true);
        $def->addAttribute('a', 'target', 'Enum#_blank,_self,_target,_top');
        $purifier = new HTMLPurifier($config);

        A slightly less efficient version of this was what was going on with old versions of HTML Purifier.

        Technical notes: ajh pointed out on in a forum topic that HTML Purifier appeared to be repeatedly writing to the cache even when a cache entry already existed. Investigation lead to the discovery of the following infelicity: caching of customized definitions didn't actually work! The problem was that even though a cache file would be written out at the end of the process, there was no way for HTML Purifier to say, Actually, I've already got a copy of your work, no need to reconfigure your customizations. This required the API to change: placing all of the customizations to the raw definition object in a conditional which could be skipped.

        php-htmlpurifier-4.4.0+dfsg1/docs/enduser-id.html010064400000000000000000000137451170566125200166410ustar00 IDs - HTML Purifier

        IDs

        What they are, why you should(n't) wear them, and how to deal with it
        Filed under End-User
        Return to the index.
        HTML Purifier End-User Documentation

        Prior to HTML Purifier 1.2.0, this library blithely accepted user input that looked like this:

        <a id="fragment">Anchor</a>

        ...presenting an attractive vector for those that would destroy standards compliance: simply set the ID to one that is already used elsewhere in the document and voila: validation breaks. There was a half-hearted attempt to prevent this by allowing users to blacklist IDs, but I suspect that no one really bothered, and thus, with the release of 1.2.0, IDs are now removed by default.

        IDs, however, are quite useful functionality to have, so if users start complaining about broken anchors you'll probably want to turn them back on with %Attr.EnableID. But before you go mucking around with the config object, it's probably worth to take some precautions to keep your page validating. Why?

        1. Standards-compliant pages are good
        2. Duplicated IDs interfere with anchors. If there are two id="foobar"s in a document, which spot does a browser presented with the fragment #foobar go to? Most browsers opt for the first appearing ID, making it impossible to references the second section. Similarly, duplicated IDs can hijack client-side scripting that relies on the IDs of elements.

        You have (currently) four ways of dealing with the problem.

        Blacklisting IDs

        Good for pages with single content source and stable templates

        Keeping in terms with the KISS principle, let us deal with the most obvious solution: preventing users from using any IDs that appear elsewhere on the document. The method is simple:

        $config->set('Attr.EnableID', true);
        $config->set('Attr.IDBlacklist' array(
            'list', 'of', 'attribute', 'values', 'that', 'are', 'forbidden'
        ));

        That being said, there are some notable drawbacks. First of all, you have to know precisely which IDs are being used by the HTML surrounding the user code. This is easier said than done: quite often the page designer and the system coder work separately, so the designer has to constantly be talking with the coder whenever he decides to add a new anchor. Miss one and you open yourself to possible standards-compliance issues.

        Furthermore, this position becomes untenable when a single web page must hold multiple portions of user-submitted content. Since there's obviously no way to find out before-hand what IDs users will use, the blacklist is helpless. And since HTML Purifier validates each segment separately, perhaps doing so at different times, it would be extremely difficult to dynamically update the blacklist in between runs.

        Finally, simply destroying the ID is extremely un-userfriendly behavior: after all, they might have simply specified a duplicate ID by accident.

        Thus, we get to our second method.

        Namespacing IDs

        Lazy developer's way, but needs user education

        This method, too, is quite simple: add a prefix to all user IDs. With this code:

        $config->set('Attr.EnableID', true);
        $config->set('Attr.IDPrefix', 'user_');

        ...this:

        <a id="foobar">Anchor!</a>

        ...turns into:

        <a id="user_foobar">Anchor!</a>

        As long as you don't have any IDs that start with user_, collisions are guaranteed not to happen. The drawback is obvious: if a user submits id="foobar", they probably expect to be able to reference their page with #foobar. You'll have to tell them, "No, that doesn't work, you have to add user_ to the beginning."

        And yes, things get hairier. Even with a nice prefix, we still have done nothing about multiple HTML Purifier outputs on one page. Thus, we have a second configuration value to piggy-back off of: %Attr.IDPrefixLocal:

        $config->set('Attr.IDPrefixLocal', 'comment' . $id . '_');

        This new attributes does nothing but append on to regular IDPrefix, but is special in that it is volatile: it's value is determined at run-time and cannot possibly be cordoned into, say, a .ini config file. As for what to put into the directive, is up to you, but I would recommend the ID number the text has been assigned in the database. Whatever you pick, however, it has to be unique and stable for the text you are validating. Note, however, that we require that %Attr.IDPrefix be set before you use this directive.

        And also remember: the user has to know what this prefix is too!

        Abstinence

        You may not want to bother. That's okay too, just don't enable IDs.

        Personally, I would take this road whenever user-submitted content would be possibly be shown together on one page. Why a blog comment would need to use anchors is beyond me.

        Denial

        To revert back to pre-1.2.0 behavior, simply:

        $config->set('Attr.EnableID', true);

        Don't come crying to me when your page mysteriously stops validating, though.

Yang There are a number of ad hoc HTML filtering solutions out there on the web (some examples including HTML_Safe, kses and SafeHtmlChecker.class.php) that claim to filter HTML properly, preventing malicious JavaScript and layout breaking HTML from getting through the parser. None of them, however, demonstrates a thorough knowledge of neither the DTD that defines the HTML nor the caveats of HTML that cannot be expressed by a DTD. Configurable filters (such as kses or PHP's built-in striptags() function) have trouble validating the contents of attributes and can be subject to security attacks due to poor configuration. Other filters take the naive approach of blacklisting known threats and tags, failing to account for the introduction of new technologies, new tags, new attributes or quirky browser behavior. However, HTML Purifier takes a different approach, one that doesn't use specification-ignorant regexes or narrow blacklists. HTML Purifier will decompose the whole document into tokens, and rigorously process the tokens by: removing non-whitelisted elements, transforming bad practice tags like into , properly checking the nesting of tags and their children and validating all attributes according to their RFCs. To my knowledge, there is nothing like this on the web yet. Not even MediaWiki, which allows an amazingly diverse mix of HTML and wikitext in its documents, gets all the nesting quirks right. Existing solutions hope that no JavaScript will slip through, but either do not attempt to ensure that the resulting output is valid XHTML or send the HTML through a draconic XML parser (and yet still get the nesting wrong: SafeHtmlChecker.class.php does not prevent tags from being nested within each other). This document no longer is a detailed description of how HTMLPurifier works, as those descriptions have been moved to the appropriate code. The first draft was drawn up after two rough code sketches and the implementation of a forgiving lexer. You may also be interested in the unit tests located in the tests/ folder, which provide a living document on how exactly the filter deals with malformed input. In summary (see corresponding classes for more details): 1. Parse document into an array of tag and text tokens (Lexer) 2. Remove all elements not on whitelist and transform certain other elements into acceptable forms (i.e. ) 3. Make document well formed while helpfully taking into account certain quirks, such as the fact that

        tags traditionally are closed by other block-level elements. 4. Run through all nodes and check children for proper order (especially important for tables). 5. Validate attributes according to more restrictive definitions based on the RFCs. 6. Translate back into a string. (Generator) HTML Purifier is best suited for documents that require a rich array of HTML tags. Things like blog comments are, in all likelihood, most appropriately written in an extremely restrictive set of markup that doesn't require all this functionality (or not written in HTML at all), although this may be changing in the future with the addition of levels of filtering. vim: et sw=4 sts=4 php-htmlpurifier-4.4.0+dfsg1/docs/enduser-security.txt010064400000000000000000000010041170566125200177500ustar00 Security Like anything that claims to afford security, HTML_Purifier can be circumvented through negligence of people.

        Speeding up HTML Purifier

        ...also known as the HELP ME LIBRARY IS TOO SLOW MY PAGE TAKE TOO LONG page
        Filed under End-User
        HTML Purifier End-User Documentation

        HTML Purifier is a very powerful library. But with power comes great responsibility, in the form of longer execution times. Remember, this library isn't lightly grazing over submitted HTML: it's deconstructing the whole thing, rigorously checking the parts, and then putting it back together.

        So, if it so turns out that HTML Purifier is kinda too slow for outbound filtering, you've got a few options:

        Inbound filtering

        Perform filtering of HTML when it's submitted by the user. Since the user is already submitting something, an extra half a second tacked on to the load time probably isn't going to be that huge of a problem. Then, displaying the content is a simple a manner of outputting it directly from your database/filesystem. The trouble with this method is that your user loses the original text, and when doing edits, will be handling the filtered text. While this may be a good thing, especially if you're using a WYSIWYG editor, it can also result in data-loss if a user makes a typo.

        Example (non-functional):

        <?php
            /**
             * FORM SUBMISSION PAGE
             * display_error($message) : displays nice error page with message
             * display_success() : displays a nice success page
             * display_form() : displays the HTML submission form
             * database_insert($html) : inserts data into database as new row
             */
            if (!empty($_POST)) {
                require_once '/path/to/library/HTMLPurifier.auto.php';
                require_once 'HTMLPurifier.func.php';
                $dirty_html = isset($_POST['html']) ? $_POST['html'] : false;
                if (!$dirty_html) {
                    display_error('You must write some HTML!');
                }
                $html = HTMLPurifier($dirty_html);
                database_insert($html);
                display_success();
                // notice that $dirty_html is *not* saved
            } else {
                display_form();
            }
        ?>

        Caching the filtered output

        Accept the submitted text and put it unaltered into the database, but then also generate a filtered version and stash that in the database. Serve the filtered version to readers, and the unaltered version to editors. If need be, you can invalidate the cache and have the cached filtered version be regenerated on the first page view. Pros? Full data retention. Cons? It's more complicated, and opens other editors up to XSS if they are using a WYSIWYG editor (to fix that, they'd have to be able to get their hands on the *really* original text served in plaintext mode).

        Example (non-functional):

        <?php
            /**
             * VIEW PAGE
             * display_error($message) : displays nice error page with message
             * cache_get($id) : retrieves HTML from fast cache (db or file)
             * cache_insert($id, $html) : inserts good HTML into cache system
             * database_get($id) : retrieves raw HTML from database
             */
            $id = isset($_GET['id']) ? (int) $_GET['id'] : false;
            if (!$id) {
                display_error('Must specify ID.');
                exit;
            }
            $html = cache_get($id); // filesystem or database
            if ($html === false) {
                // cache didn't have the HTML, generate it
                $raw_html = database_get($id);
                require_once '/path/to/library/HTMLPurifier.auto.php';
                require_once 'HTMLPurifier.func.php';
                $html = HTMLPurifier($raw_html);
                cache_insert($id, $html);
            }
            echo $html;
        ?>

        Summary

        In short, inbound filtering is the simple option and caching is the robust option (albeit with bigger storage requirements).

        There is a third option, independent of the two we've discussed: profile and optimize HTMLPurifier yourself. Be sure to report back your results if you decide to do that! Especially if you port HTML Purifier to C++. ;-)

        Tidy

        Filed under Development
        Return to the index.
        HTML Purifier End-User Documentation

        You've probably heard of HTML Tidy, Dave Raggett's little piece of software that cleans up poorly written HTML. Let me say it straight out:

        This ain't HTML Tidy!

        Rather, Tidy stands for a cool set of Tidy-inspired features in HTML Purifier that allows users to submit deprecated elements and attributes and get valid strict markup back. For example:

        <center>Centered</center>

        ...becomes:

        <div style="text-align:center;">Centered</div>

        ...when this particular fix is run on the HTML. This tutorial will give you the lowdown of what exactly HTML Purifier will do when Tidy is on, and how to fine-tune this behavior. Once again, you do not need Tidy installed on your PHP to use these features!

        What does it do?

        Tidy will do several things to your HTML:

        • Convert deprecated elements and attributes to standards-compliant alternatives
        • Enforce XHTML compatibility guidelines and other best practices
        • Preserve data that would normally be removed as per W3C

        What are levels?

        Levels describe how aggressive the Tidy module should be when cleaning up HTML. There are four levels to pick: none, light, medium and heavy. Each of these levels has a well-defined set of behavior associated with it, although it may change depending on your doctype.

        light
        This is the lenient level. If a tag or attribute is about to be removed because it isn't supported by the doctype, Tidy will step in and change into an alternative that is supported.
        medium
        This is the correctional level. At this level, all the functions of light are performed, as well as some extra, non-essential best practices enforcement. Changes made on this level are very benign and are unlikely to cause problems.
        heavy
        This is the aggressive level. If a tag or attribute is deprecated, it will be converted into a non-deprecated version, no ifs ands or buts.

        By default, Tidy operates on the medium level. You can change the level of cleaning by setting the %HTML.TidyLevel configuration directive:

        $config->set('HTML.TidyLevel', 'heavy'); // burn baby burn!

        Is the light level really light?

        It depends on what doctype you're using. If your documents are HTML 4.01 Transitional, HTML Purifier will be lazy and won't clean up your center or font tags. But if you're using HTML 4.01 Strict, HTML Purifier has no choice: it has to convert them, or they will be nuked out of existence. So while light on Transitional will result in little to no changes, light on Strict will still result in quite a lot of fixes.

        This is different behavior from 1.6 or before, where deprecated tags in transitional documents would always be cleaned up regardless. This is also better behavior.

        My pages look different!

        HTML Purifier is tasked with converting deprecated tags and attributes to standards-compliant alternatives, which usually need copious amounts of CSS. It's also not foolproof: sometimes things do get lost in the translation. This is why when HTML Purifier can get away with not doing cleaning, it won't; this is why the default value is medium and not heavy.

        Fortunately, only a few attributes have problems with the switch over. They are described below:

        Element@Attr Changes
        caption@align Firefox supports stuffing the caption on the left and right side of the table, a feature that Internet Explorer, understandably, does not have. When align equals right or left, the text will simply be aligned on the left or right side.
        img@align The implementation for align bottom is good, but not perfect. There are a few pixel differences.
        br@clear Clear both gets a little wonky in Internet Explorer. Haven't really been able to figure out why.
        hr@noshade All browsers implement this slightly differently: we've chosen to make noshade horizontal rules gray.

        There are a few more minor, although irritating, bugs. Some older browsers support deprecated attributes, but not CSS. Transformed elements and attributes will look unstyled to said browsers. Also, CSS precedence is slightly different for inline styles versus presentational markup. In increasing precedence:

        1. Presentational attributes
        2. External style sheets
        3. Inline styling

        This means that styling that may have been masked by external CSS declarations will start showing up (a good thing, perhaps). Finally, if you've turned off the style attribute, almost all of these transformations will not work. Sorry mates.

        You can review the rendering before and after of these transformations by consulting the attrTransform.php smoketest.

        I like the general idea, but the specifics bug me!

        So you want HTML Purifier to clean up your HTML, but you're not so happy about the br@clear implementation. That's perfectly fine! HTML Purifier will make accomodations:

        $config->set('HTML.Doctype', 'XHTML 1.0 Transitional');
        $config->set('HTML.TidyLevel', 'heavy'); // all changes, minus...
        $config->set('HTML.TidyRemove', 'br@clear');

        That third line does the magic, removing the br@clear fix from the module, ensuring that <br clear="both" /> will pass through unharmed. The reverse is possible too:

        $config->set('HTML.Doctype', 'XHTML 1.0 Transitional');
        $config->set('HTML.TidyLevel', 'none'); // no changes, plus...
        $config->set('HTML.TidyAdd', 'p@align');

        In this case, all transformations are shut off, except for the p@align one, which you found handy.

        To find out what the names of fixes you want to turn on or off are, you'll have to consult the source code, specifically the files in HTMLPurifier/HTMLModule/Tidy/. There is, however, a general syntax:

        Name Example Interpretation
        element font Tag transform for element
        element@attr br@clear Attribute transform for attr on element
        @attr @lang Global attribute transform for attr
        e#content_model_type blockquote#content_model_type Change of child processing implementation for e

        So... what's the lowdown?

        The lowdown is, quite frankly, HTML Purifier's default settings are probably good enough. The next step is to bump the level up to heavy, and if that still doesn't satisfy your appetite, do some fine-tuning. Other than that, don't worry about it: this all works silently and effectively in the background.

        URI Filters

        Filed under End-User
        Return to the index.
        HTML Purifier End-User Documentation

        This is a quick and dirty document to get you on your way to writing custom URI filters for your own URL filtering needs. Why would you want to write a URI filter? If you need URIs your users put into HTML to magically change into a different URI, this is exactly what you need!

        Creating the class

        Any URI filter you make will be a subclass of HTMLPurifier_URIFilter. The scaffolding is thus:

        class HTMLPurifier_URIFilter_NameOfFilter extends HTMLPurifier_URIFilter
        {
            public $name = 'NameOfFilter';
            public function prepare($config) {}
            public function filter(&$uri, $config, $context) {}
        }

        Fill in the variable $name with the name of your filter, and take a look at the two methods. prepare() is an initialization method that is called only once, before any filtering has been done of the HTML. Use it to perform any costly setup work that only needs to be done once. filter() is the guts and innards of our filter: it takes the URI and does whatever needs to be done to it.

        If you've worked with HTML Purifier, you'll recognize the $config and $context parameters. On the other hand, $uri is something unique to this section of the application: it's a HTMLPurifier_URI object. The interface is thus:

        class HTMLPurifier_URI
        {
            public $scheme, $userinfo, $host, $port, $path, $query, $fragment;
            public function HTMLPurifier_URI($scheme, $userinfo, $host, $port, $path, $query, $fragment);
            public function toString();
            public function copy();
            public function getSchemeObj($config, $context);
            public function validate($config, $context);
        }

        The first three methods are fairly self-explanatory: you have a constructor, a serializer, and a cloner. Generally, you won't be using them when you are manipulating the URI objects themselves. getSchemeObj() is a special purpose method that returns a HTMLPurifier_URIScheme object corresponding to the specific URI at hand. validate() performs general-purpose validation on the internal components of a URI. Once again, you don't need to worry about these: they've already been handled for you.

        URI format

        As a URIFilter, we're interested in the member variables of the URI object.

        Scheme The protocol for identifying (and possibly locating) a resource (http, ftp, https)
        Userinfo User information such as a username (bob)
        Host Domain name or IP address of the server (example.com, 127.0.0.1)
        Port Network port number for the server (80, 12345)
        Path Data that identifies the resource, possibly hierarchical (/path/to, ed@example.com)
        Query String of information to be interpreted by the resource (?q=search-term)
        Fragment Additional information for the resource after retrieval (#bookmark)

        Because the URI is presented to us in this form, and not http://bob@example.com:8080/foo.php?q=string#hash, it saves us a lot of trouble in having to parse the URI every time we want to filter it. For the record, the above URI has the following components:

        Scheme http
        Userinfo bob
        Host example.com
        Port 8080
        Path /foo.php
        Query q=string
        Fragment hash

        Note that there is no question mark or octothorpe in the query or fragment: these get removed during parsing.

        With this information, you can get straight to implementing your filter() method. But one more thing...

        Return value: Boolean, not URI

        You may have noticed that the URI is being passed in by reference. This means that whatever changes you make to it, those changes will be reflected in the URI object the callee had. Do not return the URI object: it is unnecessary and will cause bugs. Instead, return a boolean value, true if the filtering was successful, or false if the URI is beyond repair and needs to be axed.

        Let's suppose I wanted to write a filter that converted links with a custom image scheme to its corresponding real path on our website:

        class HTMLPurifier_URIFilter_TransformImageScheme extends HTMLPurifier_URIFilter
        {
            public $name = 'TransformImageScheme';
            public function filter(&$uri, $config, $context) {
                if ($uri->scheme !== 'image') return true;
                $img_name = $uri->path;
                // Overwrite the previous URI object
                $uri = new HTMLPurifier_URI('http', null, null, null, '/img/' . $img_name . '.png', null, null);
                return true;
            }
        }

        Notice I did not return $uri;. This filter would turn image:Foo into /img/Foo.png.

        Activating your filter

        Having a filter is all well and good, but you need to tell HTML Purifier to use it. Fortunately, this part's simple:

        $uri = $config->getDefinition('URI');
        $uri->addFilter(new HTMLPurifier_URIFilter_NameOfFilter(), $config);

        After adding a filter, you won't be able to set configuration directives. Structure your code accordingly.

        Post-filter

        Remember our TransformImageScheme filter? That filter acted before we had performed scheme validation; otherwise, the URI would have been filtered out when it was discovered that there was no image scheme. Well, a post-filter is run after scheme specific validation, so it's ideal for bulk post-processing of URIs, including munging. To specify a URI as a post-filter, set the $post member variable to TRUE.

        class HTMLPurifier_URIFilter_MyPostFilter extends HTMLPurifier_URIFilter
        {
            public $name = 'MyPostFilter';
            public $post = true;
            // ... extra code here
        }
        

        Examples

        Check the URIFilter directory for more implementation examples, and see the new directives proposal document for ideas on what could be implemented as a filter.

        Character encoding and character sets are not that difficult to understand, but so many people blithely stumble through the worlds of programming without knowing what to actually do about it, or say "Ah, it's a job for those internationalization experts." No, it is not! This document will walk you through determining the encoding of your system and how you should handle this information. It will stay away from excessive discussion on the internals of character encoding.

        This document is not designed to be read in its entirety: it will slowly introduce concepts that build on each other: you need not get to the bottom to have learned something new. However, I strongly recommend you read all the way to Why UTF-8?, because at least at that point you'd have made a conscious decision not to migrate, which can be a rewarding (but difficult) task.

        Finding the real encoding

        In the beginning, there was ASCII, and things were simple. But they weren't good, for no one could write in Cyrillic or Thai. So there exploded a proliferation of character encodings to remedy the problem by extending the characters ASCII could express. This ridiculously simplified version of the history of character encodings shows us that there are now many character encodings floating around.

        A character encoding tells the computer how to interpret raw zeroes and ones into real characters. It usually does this by pairing numbers with characters.

        There are many different types of character encodings floating around, but the ones we deal most frequently with are ASCII, 8-bit encodings, and Unicode-based encodings.

        • ASCII is a 7-bit encoding based on the English alphabet.
        • 8-bit encodings are extensions to ASCII that add a potpourri of useful, non-standard characters like é and æ. They can only add 127 characters, so usually only support one script at a time. When you see a page on the web, chances are it's encoded in one of these encodings.
        • Unicode-based encodings implement the Unicode standard and include UTF-8, UTF-16 and UTF-32/UCS-4. They go beyond 8-bits and support almost every language in the world. UTF-8 is gaining traction as the dominant international encoding of the web.

        The first step of our journey is to find out what the encoding of your website is. The most reliable way is to ask your browser:

        Mozilla Firefox
        Tools > Page Info: Encoding
        Internet Explorer
        View > Encoding: bulleted item is unofficial name

        Internet Explorer won't give you the MIME (i.e. useful/real) name of the character encoding, so you'll have to look it up using their description. Some common ones:

        IE's Description Mime Name
        Windows
        Arabic (Windows)Windows-1256
        Baltic (Windows)Windows-1257
        Central European (Windows)Windows-1250
        Cyrillic (Windows)Windows-1251
        Greek (Windows)Windows-1253
        Hebrew (Windows)Windows-1255
        Thai (Windows)TIS-620
        Turkish (Windows)Windows-1254
        Vietnamese (Windows)Windows-1258
        Western European (Windows)Windows-1252
        ISO
        Arabic (ISO)ISO-8859-6
        Baltic (ISO)ISO-8859-4
        Central European (ISO)ISO-8859-2
        Cyrillic (ISO)ISO-8859-5
        Estonian (ISO)ISO-8859-13
        Greek (ISO)ISO-8859-7
        Hebrew (ISO-Logical)ISO-8859-8-l
        Hebrew (ISO-Visual)ISO-8859-8
        Latin 9 (ISO)ISO-8859-15
        Turkish (ISO)ISO-8859-9
        Western European (ISO)ISO-8859-1
        Other
        Chinese Simplified (GB18030)GB18030
        Chinese Simplified (GB2312)GB2312
        Chinese Simplified (HZ)HZ
        Chinese Traditional (Big5)Big5
        Japanese (Shift-JIS)Shift_JIS
        Japanese (EUC)EUC-JP
        KoreanEUC-KR
        Unicode (UTF-8)UTF-8

        Internet Explorer does not recognize some of the more obscure character encodings, and having to lookup the real names with a table is a pain, so I recommend using Mozilla Firefox to find out your character encoding.

        Finding the embedded encoding

        At this point, you may be asking, "Didn't we already find out our encoding?" Well, as it turns out, there are multiple places where a web developer can specify a character encoding, and one such place is in a META tag:

        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

        You'll find this in the HEAD section of an HTML document. The text to the right of charset= is the "claimed" encoding: the HTML claims to be this encoding, but whether or not this is actually the case depends on other factors. For now, take note if your META tag claims that either:

        1. The character encoding is the same as the one reported by the browser,
        2. The character encoding is different from the browser's, or
        3. There is no META tag at all! (horror, horror!)

        Fixing the encoding

        The advice given here is for pages being served as vanilla text/html. Different practices must be used for application/xml or application/xml+xhtml, see W3C's document on XHTML media types for more information.

        If your META encoding and your real encoding match, savvy! You can skip this section. If they don't...

        No embedded encoding

        If this is the case, you'll want to add in the appropriate META tag to your website. It's as simple as copy-pasting the code snippet above and replacing UTF-8 with whatever is the mime name of your real encoding.

        For all those skeptics out there, there is a very good reason why the character encoding should be explicitly stated. When the browser isn't told what the character encoding of a text is, it has to guess: and sometimes the guess is wrong. Hackers can manipulate this guess in order to slip XSS past filters and then fool the browser into executing it as active code. A great example of this is the Google UTF-7 exploit.

        You might be able to get away with not specifying a character encoding with the META tag as long as your webserver sends the right Content-Type header, but why risk it? Besides, if the user downloads the HTML file, there is no longer any webserver to define the character encoding.

        Embedded encoding disagrees

        This is an extremely common mistake: another source is telling the browser what the character encoding is and is overriding the embedded encoding. This source usually is the Content-Type HTTP header that the webserver (i.e. Apache) sends. A usual Content-Type header sent with a page might look like this:

        Content-Type: text/html; charset=ISO-8859-1

        Notice how there is a charset parameter: this is the webserver's way of telling a browser what the character encoding is, much like the META tags we touched upon previously.

        In fact, the META tag is designed as a substitute for the HTTP header for contexts where sending headers is impossible (such as locally stored files without a webserver). Thus the name http-equiv (HTTP equivalent).

        There are two ways to go about fixing this: changing the META tag to match the HTTP header, or changing the HTTP header to match the META tag. How do we know which to do? It depends on the website's content: after all, headers and tags are only ways of describing the actual characters on the web page.

        If your website:

        ...only uses ASCII characters,
        Either way is fine, but I recommend switching both to UTF-8 (more on this later).
        ...uses special characters, and they display properly,
        Change the embedded encoding to the server encoding.
        ...uses special characters, but users often complain that they come out garbled,
        Change the server encoding to the embedded encoding.

        Changing a META tag is easy: just swap out the old encoding for the new. Changing the server (HTTP header) encoding, however, is slightly more difficult.

        Changing the server encoding

        PHP header() function

        The simplest way to handle this problem is to send the encoding yourself, via your programming language. Since you're using HTML Purifier, I'll assume PHP, although it's not too difficult to do similar things in other languages. The appropriate code is:

        header('Content-Type:text/html; charset=UTF-8');

        ...replacing UTF-8 with whatever your embedded encoding is. This code must come before any output, so be careful about stray whitespace in your application (i.e., any whitespace before output excluding whitespace within <?php ?> tags).

        PHP ini directive

        PHP also has a neat little ini directive that can save you a header call: default_charset. Using this code:

        ini_set('default_charset', 'UTF-8');

        ...will also do the trick. If PHP is running as an Apache module (and not as FastCGI, consult phpinfo() for details), you can even use htaccess to apply this property across many PHP files:

        php_value default_charset "UTF-8"

        As with all INI directives, this can also go in your php.ini file. Some hosting providers allow you to customize your own php.ini file, ask your support for details. Use:

        default_charset = "utf-8"

        Non-PHP

        You may, for whatever reason, need to set the character encoding on non-PHP files, usually plain ol' HTML files. Doing this is more of a hit-or-miss process: depending on the software being used as a webserver and the configuration of that software, certain techniques may work, or may not work.

        .htaccess

        On Apache, you can use an .htaccess file to change the character encoding. I'll defer to W3C for the in-depth explanation, but it boils down to creating a file named .htaccess with the contents:

        AddCharset UTF-8 .html

        Where UTF-8 is replaced with the character encoding you want to use and .html is a file extension that this will be applied to. This character encoding will then be set for any file directly in or in the subdirectories of directory you place this file in.

        If you're feeling particularly courageous, you can use:

        AddDefaultCharset UTF-8

        ...which changes the character set Apache adds to any document that doesn't have any Content-Type parameters. This directive, which the default configuration file sets to iso-8859-1 for security reasons, is probably why your headers mismatch with the META tag. If you would prefer Apache not to be butting in on your character encodings, you can tell it not to send anything at all:

        AddDefaultCharset Off

        ...making your internal charset declaration (usually the META tags) the sole source of character encoding information. In these cases, it is especially important to make sure you have valid META tags on your pages and all the text before them is ASCII.

        These directives can also be placed in httpd.conf file for Apache, but in most shared hosting situations you won't be able to edit this file.

        File extensions

        If you're not allowed to use .htaccess files, you can often piggy-back off of Apache's default AddCharset declarations to get your files in the proper extension. Here are Apache's default character set declarations:

        Charset File extension(s)
        ISO-8859-1.iso8859-1 .latin1
        ISO-8859-2.iso8859-2 .latin2 .cen
        ISO-8859-3.iso8859-3 .latin3
        ISO-8859-4.iso8859-4 .latin4
        ISO-8859-5.iso8859-5 .latin5 .cyr .iso-ru
        ISO-8859-6.iso8859-6 .latin6 .arb
        ISO-8859-7.iso8859-7 .latin7 .grk
        ISO-8859-8.iso8859-8 .latin8 .heb
        ISO-8859-9.iso8859-9 .latin9 .trk
        ISO-2022-JP.iso2022-jp .jis
        ISO-2022-KR.iso2022-kr .kis
        ISO-2022-CN.iso2022-cn .cis
        Big5.Big5 .big5 .b5
        WINDOWS-1251.cp-1251 .win-1251
        CP866.cp866
        KOI8-r.koi8-r .koi8-ru
        KOI8-ru.koi8-uk .ua
        ISO-10646-UCS-2.ucs2
        ISO-10646-UCS-4.ucs4
        UTF-8.utf8
        GB2312.gb2312 .gb
        utf-7.utf7
        EUC-TW.euc-tw
        EUC-JP.euc-jp
        EUC-KR.euc-kr
        shift_jis.sjis

        So, for example, a file named page.utf8.html or page.html.utf8 will probably be sent with the UTF-8 charset attached, the difference being that if there is an AddCharset charset .html declaration, it will override the .utf8 extension in page.utf8.html (precedence moves from right to left). By default, Apache has no such declaration.

        Microsoft IIS

        If anyone can contribute information on how to configure Microsoft IIS to change character encodings, I'd be grateful.

        XML

        META tags are the most common source of embedded encodings, but they can also come from somewhere else: XML Declarations. They look like:

        <?xml version="1.0" encoding="UTF-8"?>

        ...and are most often found in XML documents (including XHTML).

        For XHTML, this XML Declaration theoretically overrides the META tag. In reality, this happens only when the XHTML is actually served as legit XML and not HTML, which is almost always never due to Internet Explorer's lack of support for application/xhtml+xml (even though doing so is often argued to be good practice and is required by the XHTML 1.1 specification).

        For XML, however, this XML Declaration is extremely important. Since most webservers are not configured to send charsets for .xml files, this is the only thing a parser has to go on. Furthermore, the default for XML files is UTF-8, which often butts heads with more common ISO-8859-1 encoding (you see this in garbled RSS feeds).

        In short, if you use XHTML and have gone through the trouble of adding the XML Declaration, make sure it jives with your META tags (which should only be present if served in text/html) and HTTP headers.

        Inside the process

        This section is not required reading, but may answer some of your questions on what's going on in all this character encoding hocus pocus. If you're interested in moving on to the next phase, skip this section.

        A logical question that follows all of our wheeling and dealing with multiple sources of character encodings is "Why are there so many options?" To answer this question, we have to turn back our definition of character encodings: they allow a program to interpret bytes into human-readable characters.

        Thus, a chicken-egg problem: a character encoding is necessary to interpret the text of a document. A META tag is in the text of a document. The META tag gives the character encoding. How can we determine the contents of a META tag, inside the text, if we don't know it's character encoding? And how do we figure out the character encoding, if we don't know the contents of the META tag?

        Fortunately for us, the characters we need to write the META are in ASCII, which is pretty much universal over every character encoding that is in common use today. So, all the web-browser has to do is parse all the way down until it gets to the Content-Type tag, extract the character encoding tag, then re-parse the document according to this new information.

        Obviously this is complicated, so browsers prefer the simpler and more efficient solution: get the character encoding from a somewhere other than the document itself, i.e. the HTTP headers, much to the chagrin of HTML authors who can't set these headers.

        Why UTF-8?

        So, you've gone through all the trouble of ensuring that your server and embedded characters all line up properly and are present. Good job: at this point, you could quit and rest easy knowing that your pages are not vulnerable to character encoding style XSS attacks. However, just as having a character encoding is better than having no character encoding at all, having UTF-8 as your character encoding is better than having some other random character encoding, and the next step is to convert to UTF-8. But why?

        Internationalization

        Many software projects, at one point or another, suddenly realize that they should be supporting more than one language. Even regular usage in one language sometimes requires the occasional special character that, without surprise, is not available in your character set. Sometimes developers get around this by adding support for multiple encodings: when using Chinese, use Big5, when using Japanese, use Shift-JIS, when using Greek, etc. Other times, they use character references with great zeal.

        UTF-8, however, obviates the need for any of these complicated measures. After getting the system to use UTF-8 and adjusting for sources that are outside the hand of the browser (more on this later), UTF-8 just works. You can use it for any language, even many languages at once, you don't have to worry about managing multiple encodings, you don't have to use those user-unfriendly entities.

        User-friendly

        Websites encoded in Latin-1 (ISO-8859-1) which occasionally need a special character outside of their scope often will use a character entity reference to achieve the desired effect. For instance, θ can be written &theta;, regardless of the character encoding's support of Greek letters.

        This works nicely for limited use of special characters, but say you wanted this sentence of Chinese text: 激光, 這兩個字是甚麼意思. The ampersand encoded version would look like this:

        &#28608;&#20809;, &#36889;&#20841;&#20491;&#23383;&#26159;&#29978;&#40636;&#24847;&#24605;

        Extremely inconvenient for those of us who actually know what character entities are, totally unintelligible to poor users who don't! Even the slightly more user-friendly, "intelligible" character entities like &theta; will leave users who are uninterested in learning HTML scratching their heads. On the other hand, if they see θ in an edit box, they'll know that it's a special character, and treat it accordingly, even if they don't know how to write that character themselves.

        Wikipedia is a great case study for an application that originally used ISO-8859-1 but switched to UTF-8 when it became far to cumbersome to support foreign languages. Bots will now actually go through articles and convert character entities to their corresponding real characters for the sake of user-friendliness and searchability. See Meta's page on special characters for more details.

        Forms

        While we're on the tack of users, how do non-UTF-8 web forms deal with characters that are outside of their character set? Rather than discuss what UTF-8 does right, we're going to show what could go wrong if you didn't use UTF-8 and people tried to use characters outside of your character encoding.

        The troubles are large, extensive, and extremely difficult to fix (or, at least, difficult enough that if you had the time and resources to invest in doing the fix, you would be probably better off migrating to UTF-8). There are two types of form submission: application/x-www-form-urlencoded which is used for GET and by default for POST, and multipart/form-data which may be used by POST, and is required when you want to upload files.

        The following is a summarization of notes from FORM submission and i18n. That document contains lots of useful information, but is written in a rambly manner, so here I try to get right to the point. (Note: the original has disappeared off the web, so I am linking to the Web Archive copy.)

        application/x-www-form-urlencoded

        This is the Content-Type that GET requests must use, and POST requests use by default. It involves the ubiquitous percent encoding format that looks something like: %C3%86. There is no official way of determining the character encoding of such a request, since the percent encoding operates on a byte level, so it is usually assumed that it is the same as the encoding the page containing the form was submitted in. (RFC 3986 recommends that textual identifiers be translated to UTF-8; however, browser compliance is spotty.) You'll run into very few problems if you only use characters in the character encoding you chose.

        However, once you start adding characters outside of your encoding (and this is a lot more common than you may think: take curly "smart" quotes from Microsoft as an example), a whole manner of strange things start to happen. Depending on the browser you're using, they might:

        • Replace the unsupported characters with useless question marks,
        • Attempt to fix the characters (example: smart quotes to regular quotes),
        • Replace the character with a character entity reference, or
        • Send it anyway as a different character encoding mixed in with the original encoding (usually Windows-1252 rather than iso-8859-1 or UTF-8 interspersed in 8-bit)

        To properly guard against these behaviors, you'd have to sniff out the browser agent, compile a database of different behaviors, and take appropriate conversion action against the string (disregarding a spate of extremely mysterious, random and devastating bugs Internet Explorer manifests every once in a while). Or you could use UTF-8 and rest easy knowing that none of this could possibly happen since UTF-8 supports every character.

        multipart/form-data

        Multipart form submission takes away a lot of the ambiguity that percent-encoding had: the server now can explicitly ask for certain encodings, and the client can explicitly tell the server during the form submission what encoding the fields are in.

        There are two ways you go with this functionality: leave it unset and have the browser send in the same encoding as the page, or set it to UTF-8 and then do another conversion server-side. Each method has deficiencies, especially the former.

        If you tell the browser to send the form in the same encoding as the page, you still have the trouble of what to do with characters that are outside of the character encoding's range. The behavior, once again, varies: Firefox 2.0 converts them to character entity references while Internet Explorer 7.0 mangles them beyond intelligibility. For serious internationalization purposes, this is not an option.

        The other possibility is to set Accept-Encoding to UTF-8, which begs the question: Why aren't you using UTF-8 for everything then? This route is more palatable, but there's a notable caveat: your data will come in as UTF-8, so you will have to explicitly convert it into your favored local character encoding.

        I object to this approach on idealogical grounds: you're digging yourself deeper into the hole when you could have been converting to UTF-8 instead. And, of course, you can't use this method for GET requests.

        Well supported

        Almost every modern browser in the wild today has full UTF-8 and Unicode support: the number of troublesome cases can be counted with the fingers of one hand, and these browsers usually have trouble with other character encodings too. Problems users usually encounter stem from the lack of appropriate fonts to display the characters (once again, this applies to all character encodings and HTML entities) or Internet Explorer's lack of intelligent font picking (which can be worked around).

        We will go into more detail about how to deal with edge cases in the browser world in the Migration section, but rest assured that converting to UTF-8, if done correctly, will not result in users hounding you about broken pages.

        HTML Purifier

        And finally, we get to HTML Purifier. HTML Purifier is built to deal with UTF-8: any indications otherwise are the result of an encoder that converts text from your preferred encoding to UTF-8, and back again. HTML Purifier never touches anything else, and leaves it up to the module iconv to do the dirty work.

        This approach, however, is not perfect. iconv is blithely unaware of HTML character entities. HTML Purifier, in order to protect against sophisticated escaping schemes, normalizes all character and numeric entity references before processing the text. This leads to one important ramification:

        Any character that is not supported by the target character set, regardless of whether or not it is in the form of a character entity reference or a raw character, will be silently ignored.

        Example of this principle at work: say you have &theta; in your HTML, but the output is in Latin-1 (which, understandably, does not understand Greek), the following process will occur (assuming you've set the encoding correctly using %Core.Encoding):

        • The Encoder will transform the text from ISO 8859-1 to UTF-8 (note that theta is preserved here since it doesn't actually use any non-ASCII characters): &theta;
        • The EntityParser will transform all named and numeric character entities to their corresponding raw UTF-8 equivalents: θ
        • HTML Purifier processes the code: θ
        • The Encoder now transforms the text back from UTF-8 to ISO 8859-1. Since Greek is not supported by ISO 8859-1, it will be either ignored or replaced with a question mark: ?

        This behaviour is quite unsatisfactory. It is a deal-breaker for international applications, and it can be mildly annoying for the provincial soul who occasionally needs a special character. Since 1.4.0, HTML Purifier has provided a slightly more palatable workaround using %Core.EscapeNonASCIICharacters. The process now looks like:

        • The Encoder transforms encoding to UTF-8: &theta;
        • The EntityParser transforms entities: θ
        • HTML Purifier processes the code: θ
        • The Encoder replaces all non-ASCII characters with numeric entity reference: &#952;
        • For good measure, Encoder transforms encoding back to original (which is strictly unnecessary for 99% of encodings out there): &#952; (remember, it's all ASCII!)

        ...which means that this is only good for an occasional foray into the land of Unicode characters, and is totally unacceptable for Chinese or Japanese texts. The even bigger kicker is that, supposing the input encoding was actually ISO-8859-7, which does support theta, the character would get converted into a character entity reference anyway! (The Encoder does not discriminate).

        The current functionality is about where HTML Purifier will be for the rest of eternity. HTML Purifier could attempt to preserve the original form of the character references so that they could be substituted back in, only the DOM extension kills them off irreversibly. HTML Purifier could also attempt to be smart and only convert non-ASCII characters that weren't supported by the target encoding, but that would require reimplementing iconv with HTML awareness, something I will not do.

        So there: either it's UTF-8 or crippled international support. Your pick! (and I'm not being sarcastic here: some people could care less about other languages).

        Migrate to UTF-8

        So, you've decided to bite the bullet, and want to migrate to UTF-8. Note that this is not for the faint-hearted, and you should expect the process to take longer than you think it will take.

        The general idea is that you convert all existing text to UTF-8, and then you set all the headers and META tags we discussed earlier to UTF-8. There are many ways going about doing this: you could write a conversion script that runs through the database and re-encodes everything as UTF-8 or you could do the conversion on the fly when someone reads the page. The details depend on your system, but I will cover some of the more subtle points of migration that may trip you up.

        Configuring your database

        Most modern databases, the most prominent open-source ones being MySQL 4.1+ and PostgreSQL, support character encodings. If you're switching to UTF-8, logically speaking, you'd want to make sure your database knows about the change too. There are some caveats though:

        Legit method

        Standardization in terms of SQL syntax for specifying character encodings is notoriously spotty. Refer to your respective database's documentation on how to do this properly.

        For MySQL, ALTER will magically perform the character encoding conversion for you. However, you have to make sure that the text inside the column is what is says it is: if you had put Shift-JIS in an ISO 8859-1 column, MySQL will irreversibly mangle the text when you try to convert it to UTF-8. You'll have to convert it to a binary field, convert it to a Shift-JIS field (the real encoding), and then finally to UTF-8. Many a website had pages irreversibly mangled because they didn't realize that they'd been deluding themselves about the character encoding all along; don't become the next victim.

        For PostgreSQL, there appears to be no direct way to change the encoding of a database (as of 8.2). You will have to dump the data, and then reimport it into a new table. Make sure that your client encoding is set properly: this is how PostgreSQL knows to perform an encoding conversion.

        Many times, you will be also asked about the "collation" of the new column. Collation is how a DBMS sorts text, like ordering B, C and A into A, B and C (the problem gets surprisingly complicated when you get to languages like Thai and Japanese). If in doubt, going with the default setting is usually a safe bet.

        Once the conversion is all said and done, you still have to remember to set the client encoding (your encoding) properly on each database connection using SET NAMES (which is standard SQL and is usually supported).

        Binary

        Due to the aforementioned compatibility issues, a more interoperable way of storing UTF-8 text is to stuff it in a binary datatype. CHAR becomes BINARY, VARCHAR becomes VARBINARY and TEXT becomes BLOB. Doing so can save you some huge headaches:

        • The syntax for binary data types is very portable,
        • MySQL 4.0 has no support for character encodings, so if you want to support it you have to use binary,
        • MySQL, as of 5.1, has no support for four byte UTF-8 characters, which represent characters beyond the basic multilingual plane, and
        • You will never have to worry about your DBMS being too smart and attempting to convert your text when you don't want it to.

        MediaWiki, a very prominent international application, uses binary fields for storing their data because of point three.

        There are drawbacks, of course:

        • Database tools like PHPMyAdmin won't be able to offer you inline text editing, since it is declared as binary,
        • It's not semantically correct: it's really text not binary (lying to the database),
        • Unless you use the not-very-portable wizardry mentioned above, you have to change the encoding yourself (usually, you'd do it on the fly), and
        • You will not have collation.

        Choose based on your circumstances.

        Text editor

        For more flat-file oriented systems, you will often be tasked with converting reams of existing text and HTML files into UTF-8, as well as making sure that all new files uploaded are properly encoded. Once again, I can only point vaguely in the right direction for converting your existing files: make sure you backup, make sure you use iconv(), and make sure you know what the original character encoding of the files is (or are, depending on the tidiness of your system).

        However, I can proffer more specific advice on the subject of text editors. Many text editors have notoriously spotty Unicode support. To find out how your editor is doing, you can check out this list or Wikipedia's list. I personally use Notepad++, which works like a charm when it comes to UTF-8. Usually, you will have to explicitly tell the editor through some dialogue (usually Save as or Format) what encoding you want it to use. An editor will often offer "Unicode" as a method of saving, which is ambiguous. Make sure you know whether or not they really mean UTF-8 or UTF-16 (which is another flavor of Unicode).

        The two things to look out for are whether or not the editor supports font mixing (multiple fonts in one document) and whether or not it adds a BOM. Font mixing is important because fonts rarely have support for every language known to mankind: in order to be flexible, an editor must be able to take a little from here and a little from there, otherwise all your Chinese characters will come as nice boxes. We'll discuss BOM below.

        Byte Order Mark (headers already sent!)

        The BOM, or Byte Order Mark, is a magical, invisible character placed at the beginning of UTF-8 files to tell people what the encoding is and what the endianness of the text is. It is also unnecessary.

        Because it's invisible, it often catches people by surprise when it starts doing things it shouldn't be doing. For example, this PHP file:

        BOM<?php
        header('Location: index.php');
        ?>

        ...will fail with the all too familiar Headers already sent PHP error. And because the BOM is invisible, this culprit will go unnoticed. My suggestion is to only use ASCII in PHP pages, but if you must, make sure the page is saved WITHOUT the BOM.

        The headers the error is referring to are HTTP headers, which are sent to the browser before any HTML to tell it various information. The moment any regular text (and yes, a BOM counts as ordinary text) is output, the headers must be sent, and you are not allowed to send anymore. Thus, the error.

        If you are reading in text files to insert into the middle of another page, it is strongly advised (but not strictly necessary) that you replace out the UTF-8 byte sequence for BOM "\xEF\xBB\xBF" before inserting it in, via:

        $text = str_replace("\xEF\xBB\xBF", '', $text);

        Fonts

        Generally speaking, people who are having trouble with fonts fall into two categories:

        • Those who want to use an extremely obscure language for which there is very little support even among native speakers of the language, and
        • Those where the primary language of the text is well-supported but there are occasional characters that aren't supported.

        Yes, there's always a chance where an English user happens across a Sinhalese website and doesn't have the right font. But an English user who happens not to have the right fonts probably has no business reading Sinhalese anyway. So we'll deal with the other two edge cases.

        Obscure scripts

        If you run a Bengali website, you may get comments from users who would like to read your website but get heaps of question marks or other meaningless characters. Fixing this problem requires the installation of a font or language pack which is often highly dependent on what the language is. Here is an example of such a help file for the Bengali language; I am sure there are others out there too. You just have to point users to the appropriate help file.

        Occasional use

        A prime example of when you'll see some very obscure Unicode characters embedded in what otherwise would be very bland ASCII are letters of the International Phonetic Alphabet (IPA), use to designate pronunciations in a very standard manner (you probably see them all the time in your dictionary). Your average font probably won't have support for all of the IPA characters like ʘ (bilabial click) or ʒ (voiced postalveolar fricative). So what's a poor browser to do? Font mix! Smart browsers like Mozilla Firefox and Internet Explorer 7 will borrow glyphs from other fonts in order to make sure that all the characters display properly.

        But what happens when the browser isn't smart and happens to be the most widely used browser in the entire world? Microsoft IE 6 is not smart enough to borrow from other fonts when a character isn't present, so more often than not you'll be slapped with a nice big �. To get things to work, MSIE 6 needs a little nudge. You could configure it to use a different font to render the text, but you can achieve the same effect by selectively changing the font for blocks of special characters to known good Unicode fonts.

        Fortunately, the folks over at Wikipedia have already done all the heavy lifting for you. Get the CSS from the horses mouth here: Common.css, and search for ".IPA" There are also a smattering of other classes you can use for other purposes, check out this page for more details. For you lazy ones, this should work:

        .Unicode {
                font-family: Code2000, "TITUS Cyberbit Basic", "Doulos SIL",
                    "Chrysanthi Unicode", "Bitstream Cyberbit",
                    "Bitstream CyberBase", Thryomanes, Gentium, GentiumAlt,
                    "Lucida Grande", "Arial Unicode MS", "Microsoft Sans Serif",
                    "Lucida Sans Unicode";
                font-family /**/:inherit; /* resets fonts for everyone but IE6 */
        }

        The standard usage goes along the lines of <span class="Unicode">Crazy Unicode stuff here</span>. Characters in the Windows Glyph List usually don't need to be fixed, but for anything else you probably want to play it safe. Unless, of course, you don't care about IE6 users.

        Dealing with variable width in functions

        When people claim that PHP6 will solve all our Unicode problems, they're misinformed. It will not fix any of the aforementioned troubles. It will, however, fix the problem we are about to discuss: processing UTF-8 text in PHP.

        PHP (as of PHP5) is blithely unaware of the existence of UTF-8 (with a few notable exceptions). Sometimes, this will cause problems, other times, this won't. So far, we've avoided discussing the architecture of UTF-8, so, we must first ask, what is UTF-8? Yes, it supports Unicode, and yes, it is variable width. Other traits:

        • Every character's byte sequence is unique and will never be found inside the byte sequence of another character,
        • UTF-8 may use up to four bytes to encode a character,
        • UTF-8 text must be checked for well-formedness,
        • Pure ASCII is also valid UTF-8, and
        • Binary sorting will sort UTF-8 in the same order as Unicode.

        Each of these traits affect different domains of text processing in different ways. It is beyond the scope of this document to explain what precisely these implications are. PHPWact provides a very good reference document on what to expect from each function, although coverage is spotty in some areas. Their more general notes on character sets are also worth looking at for information on UTF-8. Some rules of thumb when dealing with Unicode text:

        • Do not EVER use functions that:
          • ...convert case (strtolower, strtoupper, ucfirst, ucwords)
          • ...claim to be case-insensitive (str_ireplace, stristr, strcasecmp)
        • Think twice before using functions that:
          • ...count characters (strlen will return bytes, not characters; str_split and word_wrap may corrupt)
          • ...convert characters to entity references (UTF-8 doesn't need entities)
          • ...do very complex string processing (*printf)

        Note: this list applies to UTF-8 encoded text only: if you have a string that you are 100% sure is ASCII, be my guest and use strtolower (HTML Purifier uses this function.)

        Regardless, always think in bytes, not characters. If you use strpos() to find the position of a character, it will be in bytes, but this usually won't matter since substr() also operates with byte indices!

        You'll also need to make sure your UTF-8 is well-formed and will probably need replacements for some of these functions. I recommend using Harry Fuecks' PHP UTF-8 library, rather than use mb_string directly. HTML Purifier also defines a few useful UTF-8 compatible functions: check out Encoder.php in the /library/HTMLPurifier/ directory.

        Well, that's it. Hopefully this document has served as a very practical springboard into knowledge of how UTF-8 works. You may have decided that you don't want to migrate yet: that's fine, just know what will happen to your output and what bug reports you may receive.

        Many other developers have already discussed the subject of Unicode, UTF-8 and internationalization, and I would like to defer to them for a more in-depth look into character sets and encodings.

        Embedding YouTube Videos

        HTML Purifier End-User Documentation

        Clients like their YouTube videos. It gives them a warm fuzzy feeling when they see a neat little embedded video player on their websites that can play the latest clips from their documentary "Fido and the Bones of Spring". All joking aside, the ability to embed YouTube videos or other active content in their pages is something that a lot of people like.

        This is a bad idea. The moment you embed anything untrusted, you will definitely be slammed by a manner of nasties that can be embedded in things from your run of the mill Flash movie to Quicktime movies. Even img tags, which HTML Purifier allows by default, can be dangerous. Be distrustful of anything that tells a browser to load content from another website automatically.

        Luckily for us, however, whitelisting saves the day. Sure, letting users include any old random flash file could be dangerous, but if it's from a specific website, it probably is okay. If no amount of pleading will convince the people upstairs that they should just settle with just linking to their movies, you may find this technique very useful.

        Looking in

        Below is custom code that allows users to embed YouTube videos. This is not favoritism: this trick can easily be adapted for other forms of embeddable content.

        Usually, websites like YouTube give us boilerplate code that you can insert into your documents. YouTube's code goes like this:

        <object width="425" height="350">
          <param name="movie" value="http://www.youtube.com/v/AyPzM5WK8ys" />
          <param name="wmode" value="transparent" />
          <embed src="http://www.youtube.com/v/AyPzM5WK8ys"
                 type="application/x-shockwave-flash"
                 wmode="transparent" width="425" height="350" />
        </object>
        

        There are two things to note about this code:

        1. <embed> is not recognized by W3C, so if you want standards-compliant code, you'll have to get rid of it.
        2. The code is exactly the same for all instances, except for the identifier AyPzM5WK8ys which tells us which movie file to retrieve.

        What point 2 means is that if we have code like <span class="youtube-embed">AyPzM5WK8ys</span> your application can reconstruct the full object from this small snippet that passes through HTML Purifier unharmed. Show me the code!

        And the corresponding usage:

        <?php
            $config->set('Filter.YouTube', true);
        ?>

        There is a bit going in the two code snippets, so let's explain.

        1. This is a Filter object, which intercepts the HTML that is coming into and out of the purifier. You can add as many filter objects as you like. preFilter() processes the code before it gets purified, and postFilter() processes the code afterwards. So, we'll use preFilter() to replace the object tag with a span, and postFilter() to restore it.
        2. The first preg_replace call replaces any YouTube code users may have embedded into the benign span tag. Span is used because it is inline, and objects are inline too. We are very careful to be extremely restrictive on what goes inside the span tag, as if an errant code gets in there it could get messy.
        3. The HTML is then purified as usual.
        4. Then, another preg_replace replaces the span tag with a fully fledged object. Note that the embed is removed, and, in its place, a data attribute was added to the object. This makes the tag standards compliant! It also breaks Internet Explorer, so we add in a bit of conditional comments with the old embed code to make it work again. It's all quite convoluted but works.

        Warning

        There are a number of possible problems with the code above, depending on how you look at it.

        Cannot change width and height

        The width and height of the final YouTube movie cannot be adjusted. This is because I am lazy. If you really insist on letting users change the size of the movie, what you need to do is package up the attributes inside the span tag (along with the movie ID). It gets complicated though: a malicious user can specify an outrageously large height and width and attempt to crash the user's operating system/browser. You need to either cap it by limiting the amount of digits allowed in the regex or using a callback to check the number.

        Trusts media's host's security

        By allowing this code onto our website, we are trusting that YouTube has tech-savvy enough people not to allow their users to inject malicious code into the Flash files. An exploit on YouTube means an exploit on your site. Even though YouTube is run by the reputable Google, it doesn't mean they are invulnerable. You're putting a certain measure of the job on an external provider (just as you have by entrusting your user input to HTML Purifier), and it is important that you are cognizant of the risk.

        Poorly written adaptations compromise security

        This should go without saying, but if you're going to adapt this code for Google Video or the like, make sure you do it right. It's extremely easy to allow a character too many in postFilter() and suddenly you're introducing XSS into HTML Purifier's XSS free output. HTML Purifier may be well written, but it cannot guard against vulnerabilities introduced after it has finished.

        Help out!

        If you write a filter for your favorite video destination (or anything like that, for that matter), send it over and it might get included with the core!

        HTML Purifier End-User Documentation

        Your website probably has a color-scheme. Green on white, purple on yellow, whatever. When you give users the ability to style their content, you may want them to keep in line with your styling. If you're website is all about light colors, you don't want a user to come in and vandalize your page with a deep maroon.

        This is an extremely silly feature proposal, but I'm writing it down anyway.

        What if the user could constrain the colors specified in inline styles? You are only allowed to use these shades of dark green for text and these shades of light yellow for the background. At the very least, you could ensure that we did not have pale yellow on white text.

        Implementation issues

        1. Requires the color attribute definition to know, currently, what the text and background colors are. This becomes difficult when classes are thrown into the mix.
        2. The user still has to define the permissible colors, how does one do something like that?
        php-htmlpurifier-4.4.0+dfsg1/docs/proposal-config.txt010064400000000000000000000020421170566125200175430ustar00 Configuration Configuration is documented on a per-use case: if a class uses a certain value from the configuration object, it has to define its name and what the value is used for. This means decentralized configuration declarations that are nevertheless error checking and a centralized configuration object. Directives are divided into namespaces, indicating the major portion of functionality they cover (although there may be overlaps). Please consult the documentation in ConfigDef for more information on these namespaces. Since configuration is dependant on context, internal classes require a configuration object to be passed as a parameter. (They also require a Context object). A majority of classes do not need the config object, but for those who do, it is a lifesaver. Definition objects are complex datatypes influenced by their respective directive namespaces (HTMLDefinition with HTML and CSSDefinition with CSS). If any of these directives is updated, HTML Purifier forces the definition to be regenerated. vim: et sw=4 sts=4 php-htmlpurifier-4.4.0+dfsg1/docs/proposal-css-extraction.txt010064400000000000000000000024441170566125200212520ustar00 Extracting inline CSS from HTML Purifier voodoofied: Assigning semantics to elements Sander Tekelenburg brought to my attention the poor programming style of inline CSS in HTML documents. In an ideal world, we wouldn't be using inline CSS at all: everything would be assigned using semantic class attributes from an external stylesheet. With ExtractStyleBlocks and CSSTidy, this is now possible (when allowed, users can specify a style element which gets extracted from the user-submitted HTML, which the application can place in the head of the HTML document). But there still is the issue of inline CSS that refuses to go away. The basic idea behind this feature is assign every element a unique identifier, and then move all of the CSS data to a style-sheet. This HTML:
        Big things!
        into
        Big things!
        and a stylesheet that is: #hp-12345 {text-align:center;} #hp-12346 {color:red;} Beyond that, HTML Purifier can magically merge common CSS values together, and a whole manner of other heuristic things. HTML Purifier should also make it easy for an admin to re-style the HTML semantically. Speed is not an issue. Also, better WYSIWYG editors are needed. vim: et sw=4 sts=4 php-htmlpurifier-4.4.0+dfsg1/docs/proposal-errors.txt010064400000000000000000000234041170566125200176170ustar00Considerations for ErrorCollection Presently, HTML Purifier takes a code-execution centric approach to handling errors. Errors are organized and grouped according to which segment of the code triggers them, not necessarily the portion of the input document that triggered the error. This means that errors are pseudo-sorted by category, rather than location in the document. One easy way to "fix" this problem would be to re-sort according to line number. However, the "category" style information we derive from naively following program execution is still useful. After all, each of the strategies which can report errors still process the document mostly linearly. Furthermore, not only do they process linearly, but the way they pass off operations to sub-systems mirrors that of the document. For example, AttrValidator will linearly proceed through elements, and on each element will use AttrDef to validate those contents. From there, the attribute might have more sub-components, which have execution passed off accordingly. In fact, each strategy handles a very specific class of "error." RemoveForeignElements - element tokens MakeWellFormed - element token ordering FixNesting - element token ordering ValidateAttributes - attributes of elements The crucial point is that while we care about the hierarchy governing these different errors, we *don't* care about any other information about what actually happens to the elements. This brings up another point: if HTML Purifier fixes something, this is not really a notice/warning/error; it's really a suggestion of a way to fix the aforementioned defects. In short, the refactoring to take this into account kinda sucks. Errors should not be recorded in order that they are reported. Instead, they should be bound to the line (and preferably element) in which they were found. This means we need some way to uniquely identify every element in the document, which doesn't presently exist. An easy way of adding this would be to track line columns. An important ramification of this is that we *must* use the DirectLex implementation. 1. Implement column numbers for DirectLex [DONE!] 2. Disable error collection when not using DirectLex [DONE!] Next, we need to re-orient all of the error declarations to place CurrentToken at utmost important. Since this is passed via Context, it's not always clear if that's available. ErrorCollector should complain HARD if it isn't available. There are some locations when we don't have a token available. These include: * Lexing - this can actually have a row and column, but NOT correspond to a token * End of document errors - bump this to the end Actually, we *don't* have to complain if CurrentToken isn't available; we just set it as a document-wide error. And actually, nothing needs to be done here. Something interesting to consider is whether or not we care about the locations of attributes and CSS properties, i.e. the sub-objects that compose these things. In terms of consistency, at the very least attributes should have column/line numbers attached to them. However, this may be overkill, as attributes are uniquely identifiable. You could go even further, with CSS, but they are also uniquely identifiable. Bottom-line is, however, this information must be available, in form of the CurrentAttribute and CurrentCssProperty (theoretical) context variables, and it must be used to organize the errors that the sub-processes may throw. There is also a hierarchy of sorts that may make merging this into one context variable more sense, if it hadn't been for HTML's reasonably rigid structure. A CSS property will never contain an HTML attribute. So we won't ever get recursive relations, and having multiple depths won't ever make sense. Leave this be. We already have this information, and consequently, using start and end is *unnecessary*, so long as the context variables are set appropriately. We don't care if an error was thrown by an attribute transform or an attribute definition; to the end user these are the same (for a developer, they are different, but they're better off with a stack trace (which we should add support for) in such cases). 3. Remove start()/end() code. Don't get rid of recursion, though [DONE] 4. Setup ErrorCollector to use context information to setup hierarchies. This may require a different internal format. Use objects if it gets complex. [DONE] ASIDE More on this topic: since we are now binding errors to lines and columns, a particular error can have three relationships to that specific location: 1. The token at that location directly RemoveForeignElements AttrValidator (transforms) MakeWellFormed 2. A "component" of that token (i.e. attribute) AttrValidator (removals) 3. A modification to that node (i.e. contents from start to end token) as a whole FixNesting This needs to be marked accordingly. In the presentation, it might make sense keep (3) separate, have (2) a sublist of (1). (1) can be a closing tag, in which case (3) makes no sense at all, OR it should be related with its opening tag (this may not necessarily be possible before MakeWellFormed is run). So, the line and column counts as our identifier, so: $errors[$line][$col] = ... Then, we need to identify case 1, 2 or 3. They are identified as such: 1. Need some sort of semaphore in RemoveForeignElements, etc. 2. If CurrentAttr/CurrentCssProperty is non-null 3. Default (FixNesting, MakeWellFormed) One consideration about (1) is that it usually is actually a (3) modification, but we have no way of knowing about that because of various optimizations. However, they can probably be treated the same. The other difficulty is that (3) is never a line and column; rather, it is a range (i.e. a duple) and telling the user the very start of the range may confuse them. For example, Foo
        bar
        ^ ^ The node being operated on is , so the error would be assigned to the first caret, with a "node reorganized" error. Then, the ChildDef would have submitted its own suggestions and errors with regard to what's going in the internals. So I suppose this is ok. :-) Now, the structure of the earlier mentioned ... would be something like this: object { type = (token|attr|property), value, // appropriate for type errors => array(), sub-errors = [recursive], } This helps us keep things agnostic. It is also sufficiently complex enough to warrant an object. So, more wanking about the object format is in order. The way HTML Purifier is currently setup, the only possible hierarchy is: token -> attr -> css property These relations do not exist all of the time; a comment or end token would not ever have any attributes, and non-style attributes would never have CSS properties associated with them. I believe that it is worth supporting multiple paths. At some point, we might have a hierarchy like: * -> syntax -> token -> attr -> css property -> url -> css stylesheet

Because // most parsers give little thought to Unicode, treatment // of these codepoints is basically uniform, even for // punctuation-like codepoints. These characters can // show up in non-Western pages and are supported by most // major browsers, for example: "ï¼­ï¼³ 明æœ" is a // legitimate font-name // . See // the CSS3 spec for more examples: // // You can see live samples of these on the Internet: // // However, most of these fonts have ASCII equivalents: // for example, 'MS Mincho', and it's considered // professional to use ASCII font names instead of // Unicode font names. Thanks Takeshi Terada for // providing this information. // The following characters, to my knowledge, have not been // used to name font names. // - Single quote. While theoretically you might find a // font name that has a single quote in its name (serving // as an apostrophe, e.g. Dave's Scribble), I haven't // been able to find any actual examples of this. // Internet Explorer's cssText translation (which I // believe is invoked by innerHTML) normalizes any // quoting to single quotes, and fails to escape single // quotes. (Note that this is not IE's behavior for all // CSS properties, just some sort of special casing for // font-family). So a single quote *cannot* be used // safely in the font-family context if there will be an // innerHTML/cssText translation. Note that Firefox 3.x // does this too. // - Double quote. In IE, these get normalized to // single-quotes, no matter what the encoding. (Fun // fact, in IE8, the 'content' CSS property gained // support, where they special cased to preserve encoded // double quotes, but still translate unadorned double // quotes into single quotes.) So, because their // fixpoint behavior is identical to single quotes, they // cannot be allowed either. Firefox 3.x displays // single-quote style behavior. // - Backslashes are reduced by one (so \\ -> \) every // iteration, so they cannot be used safely. This shows // up in IE7, IE8 and FF3 // - Semicolons, commas and backticks are handled properly. // - The rest of the ASCII punctuation is handled properly. // We haven't checked what browsers do to unadorned // versions, but this is not important as long as the // browser doesn't /remove/ surrounding quotes (as IE does // for HTML). // // With these results in hand, we conclude that there are // various levels of safety: // - Paranoid: alphanumeric, spaces and dashes(?) // - International: Paranoid + non-ASCII Unicode // - Edgy: Everything except quotes, backslashes // - NoJS: Standards compliance, e.g. sod IE.

Otherwise, it will use a relaxed CDATA definition. If true, the relaxed CDATA definition is forced; if false, the NMTOKENS definition is forced. To get behavior of HTML Purifier prior to 4.0.0, set this directive to false. Some rational behind the auto-detection: in previous versions of HTML Purifier, it was assumed that the form of class was NMTOKENS, as specified by the XHTML Modularization (representing XHTML 1.1 and XHTML 2.0). The DTDs for HTML 4.01 and XHTML 1.0, however specify class as CDATA. HTML 5 effectively defines it as CDATA, but with the additional constraint that each name should be unique (this is not explicitly outlined in previous specifications). --# vim: et sw=4 sts=4 php-htmlpurifier-4.4.0+dfsg1/library/HTMLPurifier/ConfigSchema/schema/Attr.DefaultImageAlt.txt010064400000000000000000000007371170566125200271270ustar00Attr.DefaultImageAlt TYPE: string/null DEFAULT: null VERSION: 3.2.0 --DESCRIPTION-- This is the content of the alt tag of an image if the user had not previously specified an alt attribute.

If you need to allow multiple sets of user content on web page, you may need to have a seperate prefix that changes with each iteration. This way, seperately submitted user content displayed on the same page doesn't clobber each other. Ideal values are unique identifiers for the content it represents (i.e. the id of the row in the database). Be sure to add a seperator (like an underscore) at the end. Warning: this directive will not work unless %Attr.IDPrefix is set to a non-empty value! --# vim: et sw=4 sts=4 php-htmlpurifier-4.4.0+dfsg1/library/HTMLPurifier/ConfigSchema/schema/AutoFormat.AutoParagraph.txt010064400000000000000000000021621170566125200300360ustar00AutoFormat.AutoParagraph TYPE: bool VERSION: 2.0.1 DEFAULT: false --DESCRIPTION--

        This directive turns on auto-paragraphing, where double newlines are converted in to paragraphs whenever possible. Auto-paragraphing:

        • Always applies to inline elements or text in the root node,
        • Applies to inline elements or text with double newlines in nodes that allow paragraph tags,
        • Applies to double newlines in paragraph tags

        p tags must be allowed for this directive to take effect. We do not use br tags for paragraphing, as that is semantically incorrect.

        To prevent auto-paragraphing as a content-producer, refrain from using double-newlines except to specify a new paragraph or in contexts where it has special meaning (whitespace usually has no meaning except in tags like pre, so this should not be difficult.) To prevent the paragraphing of inline text adjacent to block elements, wrap them in div tags (the behavior is slightly different outside of the root node.)

        When %AutoFormat.RemoveEmpty and %AutoFormat.RemoveEmpty.RemoveNbsp are enabled, this directive defines what HTML elements should not be removede if they have only a non-breaking space in them.

        --# vim: et sw=4 sts=4 library/HTMLPurifier/ConfigSchema/schema/AutoFormat.RemoveEmpty.RemoveNbsp.txt010064400000000000000000000007011170566125200315510ustar00php-htmlpurifier-4.4.0+dfsg1AutoFormat.RemoveEmpty.RemoveNbsp TYPE: bool VERSION: 4.0.0 DEFAULT: false --DESCRIPTION--

        When enabled, HTML Purifier will treat any elements that contain only non-breaking spaces as well as regular whitespace as empty, and remove them when %AutoForamt.RemoveEmpty is enabled.

        See %AutoFormat.RemoveEmpty.RemoveNbsp.Exceptions for a list of elements that don't have this behavior applied to them.

        --# vim: et sw=4 sts=4 php-htmlpurifier-4.4.0+dfsg1/library/HTMLPurifier/ConfigSchema/schema/AutoFormat.RemoveEmpty.txt010064400000000000000000000033561170566125200275620ustar00AutoFormat.RemoveEmpty TYPE: bool VERSION: 3.2.0 DEFAULT: false --DESCRIPTION--

        When enabled, HTML Purifier will attempt to remove empty elements that contribute no semantic information to the document. The following types of nodes will be removed:

        • Tags with no attributes and no content, and that are not empty elements (remove <a></a> but not <br />), and
        • Tags with no content, except for:
          • The colgroup element, or
          • Elements with the id or name attribute, when those attributes are permitted on those elements.

        Please be very careful when using this functionality; while it may not seem that empty elements contain useful information, they can alter the layout of a document given appropriate styling. This directive is most useful when you are processing machine-generated HTML, please avoid using it on regular user HTML.

        Elements that contain only whitespace will be treated as empty. Non-breaking spaces, however, do not count as whitespace. See %AutoFormat.RemoveEmpty.RemoveNbsp for alternate behavior.

        This algorithm is not perfect; you may still notice some empty tags, particularly if a node had elements, but those elements were later removed because they were not permitted in that context, or tags that, after being auto-closed by another tag, where empty. This is for safety reasons to prevent clever code from breaking validation. The general rule of thumb: if a tag looked empty on the way in, it will get removed; if HTML Purifier made it empty, it will stay.

Tricky CSS properties/values can drastically modify page layout or be used for deceptive practices but do not directly constitute a security risk. For example, display:none; is considered a tricky property that will only be allowed if this directive is set to true. --# vim: et sw=4 sts=4 php-htmlpurifier-4.4.0+dfsg1/library/HTMLPurifier/ConfigSchema/schema/CSS.AllowedFonts.txt010064400000000000000000000005371170566125200262540ustar00CSS.AllowedFonts TYPE: lookup/null VERSION: 4.3.0 DEFAULT: NULL --DESCRIPTION--

        Allows you to manually specify a set of allowed fonts. If NULL, all fonts are allowed. This directive affects generic names (serif, sans-serif, monospace, cursive, fantasy) as well as specific font families.

        --# vim: et sw=4 sts=4 php-htmlpurifier-4.4.0+dfsg1/library/HTMLPurifier/ConfigSchema/schema/CSS.AllowedProperties.txt010064400000000000000000000011401170566125200273060ustar00CSS.AllowedProperties TYPE: lookup/null VERSION: 3.1.0 DEFAULT: NULL --DESCRIPTION--

        If HTML Purifier's style attributes set is unsatisfactory for your needs, you can overload it with your own list of tags to allow. Note that this method is subtractive: it does its job by taking away from HTML Purifier usual feature set, so you cannot add an attribute that HTML Purifier never supported in the first place.

        Warning: If another directive conflicts with the elements here, that directive will win and override.

        This is the logical inverse of %CSS.AllowedProperties, and it will override that directive or any other directive. If possible, %CSS.AllowedProperties is recommended over this directive, because it can sometimes be difficult to tell whether or not you've forbidden all of the CSS properties you truly would like to disallow.

        This parameter sets the maximum allowed length on img tags, effectively the width and height properties. Only absolute units of measurement (in, pt, pc, mm, cm) and pixels (px) are allowed. This is in place to prevent imagecrash attacks, disable with null at your own risk. This directive is similar to %HTML.MaxImgLength, and both should be concurrently edited, although there are subtle differences in the input format (the CSS max is a number with a unit).

        This directive enables aggressive pre-filter fixes HTML Purifier can perform in order to ensure that open angled-brackets do not get killed during parsing stage. Enabling this will result in two preg_replace_callback calls and at least two preg_replace calls for every HTML document parsed; if your users make very well-formed HTML, you can set this directive false. This has no effect when DirectLex is used.

        Notice: This directive's default turned from false to true in HTML Purifier 3.2.0.

        Specifies the number of tokens the DirectLex line number tracking implementations should process before attempting to resyncronize the current line count by manually counting all previous new-lines. When at 0, this functionality is disabled. Lower values will decrease performance, and this is only strictly necessary if the counting algorithm is buggy (in which case you should report it as a bug).

This technique has notable deficiencies: absolutely no characters outside of the selected character encoding will be preserved, not even the ones that have been ampersand escaped (this is due to a UTF-8 specific feature that automatically resolves all entities), making it pretty useless for anything except the most I18N-blind applications, although %Core.EscapeNonASCIICharacters offers fixes this trouble with another tradeoff.

This means that even characters that can be expressed in the non-UTF-8 encoding will be entity-ized, which can be a real downer for encodings like Big5. It also assumes that the ASCII repetoire is available, although this is the case for almost all encodings. Anyway, use UTF-8! --# vim: et sw=4 sts=4 php-htmlpurifier-4.4.0+dfsg1/library/HTMLPurifier/ConfigSchema/schema/Core.HiddenElements.txt010064400000000000000000000010771170566125200270030ustar00Core.HiddenElements TYPE: lookup --DEFAULT-- array ( 'script' => true, 'style' => true, ) --DESCRIPTION--

        This directive is a lookup array of elements which should have their contents removed when they are not allowed by the HTML definition. For example, the contents of a script tag are not normally shown in a document, so if script tags are to be removed, their contents should be removed to. This is opposed to a b tag, which defines some presentational changes but does not hide its contents.

        This parameter determines what lexer implementation can be used. The valid values are:

        null
        Recommended, the lexer implementation will be auto-detected based on your PHP-version and configuration.
        string lexer identifier
        This is a slim way of manually overridding the implementation. Currently recognized values are: DOMLex (the default PHP5 implementation) and DirectLex (the default PHP4 implementation). Only use this if you know what you are doing: usually, the auto-detection will manage things for cases you aren't even aware of.
        object lexer instance
        Super-advanced: you can specify your own, custom, implementation that implements the interface defined by HTMLPurifier_Lexer. I may remove this option simply because I don't expect anyone to use it.

        If true, HTML Purifier will add line number information to all tokens. This is useful when error reporting is turned on, but can result in significant performance degradation and should not be used when unnecessary. This directive must be used with the DirectLex lexer, as the DOMLex lexer does not (yet) support this functionality. If the value is null, an appropriate value will be selected based on other configuration.

        Whether or not to escape the dangerous characters <, > and & as \3C, \3E and \26, respectively. This is can be safely set to false if the contents of StyleBlocks will be placed in an external stylesheet, where there is no risk of it being interpreted as HTML.

        If you would like users to be able to define external stylesheets, but only allow them to specify CSS declarations for a specific node and prevent them from fiddling with other elements, use this directive. It accepts any valid CSS selector, and will prepend this to any CSS declaration extracted from the document. For example, if this directive is set to #user-content and a user uses the selector a:hover, the final selector will be #user-content a:hover.

        The comma shorthand may be used; consider the above example, with #user-content, #user-content2, the final selector will be #user-content a:hover, #user-content2 a:hover.

        Warning: It is possible for users to bypass this measure using a naughty + selector. This is a bug in CSS Tidy 1.3, not HTML Purifier, and I am working to get it fixed. Until then, HTML Purifier performs a basic check to prevent this.

        If left NULL, HTML Purifier will attempt to instantiate a csstidy class to use for internal cleaning. This will usually be good enough.

        However, for trusted user input, you can set this to false to disable cleaning. In addition, you can supply your own concrete implementation of Tidy's interface to use, although I don't know why you'd want to do that.

        This directive turns on the style block extraction filter, which removes style blocks from input HTML, cleans them up with CSSTidy, and places them in the StyleBlocks context variable, for further use by you, usually to be placed in an external stylesheet, or a style block in the head of your document.

        Sample usage:

        ';
        ?>
        
        
        
          Filter.ExtractStyleBlocks
        body {color:#F00;} Some text';
        
            $config = HTMLPurifier_Config::createDefault();
            $config->set('Filter', 'ExtractStyleBlocks', true);
            $purifier = new HTMLPurifier($config);
        
            $html = $purifier->purify($dirty);
        
            // This implementation writes the stylesheets to the styles/ directory.
            // You can also echo the styles inside the document, but it's a bit
            // more difficult to make sure they get interpreted properly by
            // browsers; try the usual CSS armoring techniques.
            $styles = $purifier->context->get('StyleBlocks');
            $dir = 'styles/';
            if (!is_dir($dir)) mkdir($dir);
            $hash = sha1($_GET['html']);
            foreach ($styles as $i => $style) {
                file_put_contents($name = $dir . $hash . "_$i");
                echo '';
            }
        ?>
        
        
          
        ]]>

        Warning: It is possible for a user to mount an imagecrash attack using this CSS. Counter-measures are difficult; it is not simply enough to limit the range of CSS lengths (using relative lengths with many nesting levels allows for large values to be attained without actually specifying them in the stylesheet), and the flexible nature of selectors makes it difficult to selectively disable lengths on image tags (HTML Purifier, however, does disable CSS width and height in inline styling). There are probably two effective counter measures: an explicit width and height set to auto in all images in your document (unlikely) or the disabling of width and height (somewhat reasonable). Whether or not these measures should be used is left to the reader.

        Warning: Deprecated in favor of %HTML.SafeObject and %Output.FlashCompat (turn both on to allow YouTube videos and other Flash content).

        This directive enables YouTube video embedding in HTML Purifier. Check this document on embedding videos for more information on what this filter does.

        This is a preferred convenience directive that combines %HTML.AllowedElements and %HTML.AllowedAttributes. Specify elements and attributes that are allowed using: element1[attr1|attr2],element2.... For example, if you would like to only allow paragraphs and links, specify a[href],p. You can specify attributes that apply to all elements using an asterisk, e.g. *[lang]. You can also use newlines instead of commas to separate elements.

        Warning: All of the constraints on the component directives are still enforced. The syntax is a subset of TinyMCE's valid_elements whitelist: directly copy-pasting it here will probably result in broken whitelists. If %HTML.AllowedElements or %HTML.AllowedAttributes are set, this directive has no effect.

        --# vim: et sw=4 sts=4 php-htmlpurifier-4.4.0+dfsg1/library/HTMLPurifier/ConfigSchema/schema/HTML.AllowedAttributes.txt010064400000000000000000000011371170566125200274220ustar00HTML.AllowedAttributes TYPE: lookup/null VERSION: 1.3.0 DEFAULT: NULL --DESCRIPTION--

        If HTML Purifier's attribute set is unsatisfactory, overload it! The syntax is "tag.attr" or "*.attr" for the global attributes (style, id, class, dir, lang, xml:lang).

        Warning: If another directive conflicts with the elements here, that directive will win and override. For example, %HTML.EnableAttrID will take precedence over *.id in this directive. You must set that directive to true before you can use IDs at all.

Trailing and leading spaces are removed prior to running this regular expression. Warning: Make sure you specify correct anchor metacharacters ^regex$, otherwise you may accept comments that you did not mean to! In particular, the regex /foo|bar/ is probably not sufficiently strict, since it also allows foobar. See also %HTML.AllowedComments (these directives are union'ed together, so a comment is considered valid if any directive deems it valid.) --# vim: et sw=4 sts=4 php-htmlpurifier-4.4.0+dfsg1/library/HTMLPurifier/ConfigSchema/schema/HTML.AllowedElements.txt010064400000000000000000000015621170566125200270520ustar00HTML.AllowedElements TYPE: lookup/null VERSION: 1.3.0 DEFAULT: NULL --DESCRIPTION--

        If HTML Purifier's tag set is unsatisfactory for your needs, you can overload it with your own list of tags to allow. If you change this, you probably also want to change %HTML.AllowedAttributes; see also %HTML.Allowed which lets you set allowed elements and attributes at the same time.

        If you attempt to allow an element that HTML Purifier does not know about, HTML Purifier will raise an error. You will need to manually tell HTML Purifier about this element by using the advanced customization features.

        A doctype comes with a set of usual modules to use. Without having to mucking about with the doctypes, you can quickly activate or disable these modules by specifying which modules you wish to allow with this directive. This is most useful for unit testing specific modules, although end users may find it useful for their own ends.

        If you specify a module that does not exist, the manager will silently fail to use it, so be careful! User-defined modules are not affected by this directive. Modules defined in %HTML.CoreModules are not affected by this directive.

        String name of element to wrap inline elements that are inside a block context. This only occurs in the children of blockquote in strict mode.

        Example: by default value, <blockquote>Foo</blockquote> would become <blockquote><p>Foo</p></blockquote>. The <p> tags can be replaced with whatever you desire, as long as it is a block level element.

        Unique identifier for a custom-built HTML definition. If you edit the raw version of the HTMLDefinition, introducing changes that the configuration object does not reflect, you must specify this variable. If you change your custom edits, you should change this directive, or clear your cache. Example:

        $config = HTMLPurifier_Config::createDefault();
        $config->set('HTML', 'DefinitionID', '1');
        $def = $config->getHTMLDefinition();
        $def->addAttribute('a', 'tabindex', 'Number');
        

        In the above example, the configuration is still at the defaults, but using the advanced API, an extra attribute has been added. The configuration object normally has no way of knowing that this change has taken place, so it needs an extra directive: %HTML.DefinitionID. If someone else attempts to use the default configuration, these two pieces of code will not clobber each other in the cache, since one has an extra directive attached to it.

        You must specify a value to this directive to use the advanced API features.

        Revision identifier for your custom definition specified in %HTML.DefinitionID. This serves the same purpose: uniquely identifying your custom definition, but this one does so in a chronological context: revision 3 is more up-to-date then revision 2. Thus, when this gets incremented, the cache handling is smart enough to clean up any older revisions of your definition as well as flush the cache.

        While this directive is similar to %HTML.AllowedAttributes, for forwards-compatibility with XML, this attribute has a different syntax. Instead of tag.attr, use tag@attr. To disallow href attributes in a tags, set this directive to a@href. You can also disallow an attribute globally with attr or *@attr (either syntax is fine; the latter is provided for consistency with %HTML.AllowedAttributes).

        Warning: This directive complements %HTML.ForbiddenElements, accordingly, check out that directive for a discussion of why you should think twice before using this directive.

        --# vim: et sw=4 sts=4 php-htmlpurifier-4.4.0+dfsg1/library/HTMLPurifier/ConfigSchema/schema/HTML.ForbiddenElements.txt010064400000000000000000000013621170566125200273550ustar00HTML.ForbiddenElements TYPE: lookup VERSION: 3.1.0 DEFAULT: array() --DESCRIPTION--

        This was, perhaps, the most requested feature ever in HTML Purifier. Please don't abuse it! This is the logical inverse of %HTML.AllowedElements, and it will override that directive, or any other directive.

        If possible, %HTML.Allowed is recommended over this directive, because it can sometimes be difficult to tell whether or not you've forbidden all of the behavior you would like to disallow. If you forbid img with the expectation of preventing images on your site, you'll be in for a nasty surprise when people start using the background-image CSS property.

        This directive controls the maximum number of pixels in the width and height attributes in img tags. This is in place to prevent imagecrash attacks, disable with null at your own risk. This directive is similar to %CSS.MaxImgLength, and both should be concurrently edited, although there are subtle differences in the input format (the HTML max is an integer).

        Whether or not to permit embed tags in documents, with a number of extra security features added to prevent script execution. This is similar to what websites like MySpace do to embed tags. Embed is a proprietary element and will cause your website to stop validating; you should see if you can use %Output.FlashCompat with %HTML.SafeObject instead first.

        Whether or not to permit iframe tags in untrusted documents. This directive must be accompanied by a whitelist of permitted iframes, such as %URI.SafeIframeRegexp, otherwise it will fatally error. This directive has no effect on strict doctypes, as iframes are not valid.

        If true, HTML Purifier will protect against Internet Explorer's mishandling of the innerHTML attribute by appending a space to any attribute that does not contain angled brackets, spaces or quotes, but contains a backtick. This slightly changes the semantics of any given attribute, so if this is unacceptable and you do not use innerHTML on any of your pages, you can turn this directive off.

        Newline string to format final output with. If left null, HTML Purifier will auto-detect the default newline type of the system and use that; you can manually override it here. Remember, \r\n is Windows, \r is Mac, and \n is Unix.

        If true, HTML Purifier will sort attributes by name before writing them back to the document, converting a tag like: <el b="" a="" c="" /> to <el a="" b="" c="" />. This is a workaround for a bug in FCKeditor which causes it to swap attributes order, adding noise to text diffs. If you're not seeing this bug, chances are, you don't need this directive.

        Determines whether or not to run Tidy on the final output for pretty formatting reasons, such as indentation and wrap.

        This can greatly improve readability for editors who are hand-editing the HTML, but is by no means necessary as HTML Purifier has already fixed all major errors the HTML may have had. Tidy is a non-default extension, and this directive will silently fail if Tidy is not available.

        If you are looking to make the overall look of your page's source better, I recommend running Tidy on the entire page rather than just user-content (after all, the indentation relative to the containing blocks will be incorrect).

        The base URI is the URI of the document this purified HTML will be inserted into. This information is important if HTML Purifier needs to calculate absolute URIs from relative URIs, such as when %URI.MakeAbsolute is on. You may use a non-absolute URI for this value, but behavior may vary (%URI.MakeAbsolute deals nicely with both absolute and relative paths, but forwards-compatibility is not guaranteed). Warning: If set, the scheme on this URI overrides the one specified by %URI.DefaultScheme.

This prevents access tracking (good for email viewers), bandwidth leeching, cross-site request forging, goatse.cx posting, and other nasties, but also results in a loss of end-user functionality (they can't directly post a pic they posted from Flickr anymore).

        Disables embedding resources, essentially meaning no pictures. You can still link to them though. See %URI.DisableExternalResources for why this might be a good idea.

        Note: While this directive has been available since 1.3.0, it didn't actually start doing anything until 4.2.0.

        Defines the domain name of the server, so we can determine whether or an absolute URI is from your website or not. Not strictly necessary, as users should be using relative URIs to reference resources on your website. It will, however, let you use absolute URIs to link to subdomains of the domain you post here: i.e. example.com will allow sub.example.com. However, higher up domains will still be excluded: if you set %URI.Host to sub.example.com, example.com will be blocked. Note: This directive overrides %URI.Base because a given page may be on a sub-domain, but you wish HTML Purifier to be more relaxed and allow some of the parent domains too.

        Converts all URIs into absolute forms. This is useful when the HTML being filtered assumes a specific base path, but will actually be viewed in a different context (and setting an alternate base URI is not possible). %URI.Base must be set for this directive to work.

        --# vim: et sw=4 sts=4 php-htmlpurifier-4.4.0+dfsg1/library/HTMLPurifier/ConfigSchema/schema/URI.Munge.txt010064400000000000000000000053071170566125200247350ustar00URI.Munge TYPE: string/null VERSION: 1.3.0 DEFAULT: NULL --DESCRIPTION--

        Munges all browsable (usually http, https and ftp) absolute URIs into another URI, usually a URI redirection service. This directive accepts a URI, formatted with a %s where the url-encoded original URI should be inserted (sample: http://www.google.com/url?q=%s).

        Uses for this directive:

        • Prevent PageRank leaks, while being fairly transparent to users (you may also want to add some client side JavaScript to override the text in the statusbar). Notice: Many security experts believe that this form of protection does not deter spam-bots.
        • Redirect users to a splash page telling them they are leaving your website. While this is poor usability practice, it is often mandated in corporate environments.

        Prior to HTML Purifier 3.1.1, this directive also enabled the munging of browsable external resources, which could break things if your redirection script was a splash page or used meta tags. To revert to previous behavior, please use %URI.MungeResources.

        You may want to also use %URI.MungeSecretKey along with this directive in order to enforce what URIs your redirector script allows. Open redirector scripts can be a security risk and negatively affect the reputation of your domain name.

        Starting with HTML Purifier 3.1.1, there is also these substitutions:

        Key Description Example <a href="">
        %r 1 - The URI embeds a resource
        (blank) - The URI is merely a link
        %n The name of the tag this URI came from a
        %m The name of the attribute this URI came from href
        %p The name of the CSS property this URI came from, or blank if irrelevant

        Admittedly, these letters are somewhat arbitrary; the only stipulation was that they couldn't be a through f. r is for resource (I would have preferred e, but you take what you can get), n is for name, m was picked because it came after n (and I couldn't use a), p is for property.

        --# vim: et sw=4 sts=4 php-htmlpurifier-4.4.0+dfsg1/library/HTMLPurifier/ConfigSchema/schema/URI.MungeResources.txt010064400000000000000000000011431170566125200266220ustar00URI.MungeResources TYPE: bool VERSION: 3.1.1 DEFAULT: false --DESCRIPTION--

        If true, any URI munging directives like %URI.Munge will also apply to embedded resources, such as <img src="">. Be careful enabling this directive if you have a redirector script that does not use the Location HTTP header; all of your images and other embedded resources will break.

        Warning: It is strongly advised you use this in conjunction %URI.MungeSecretKey to mitigate the security risk of an open redirector.

        This directive enables secure checksum generation along with %URI.Munge. It should be set to a secure key that is not shared with anyone else. The checksum can be placed in the URI using %t. Use of this checksum affords an additional level of protection by allowing a redirector to check if a URI has passed through HTML Purifier with this line:

        $checksum === sha1($secret_key . ':' . $url)

        If the output is TRUE, the redirector script should accept the URI.

        Please note that it would still be possible for an attacker to procure secure hashes en-mass by abusing your website's Preview feature or the like, but this service affords an additional level of protection that should be combined with website blacklisting.

        Remember this has no effect if %URI.Munge is not on.

        A PCRE regular expression that will be matched against an iframe URI. This is a relatively inflexible scheme, but works well enough for the most common use-case of iframes: embedded video. This directive only has an effect if %HTML.SafeIframe is enabled. Here are some example values:

        • %^http://www.youtube.com/embed/% - Allow YouTube videos
        • %^http://player.vimeo.com/video/% - Allow Vimeo videos
        • %^http://(www.youtube.com/embed/|player.vimeo.com/video/)% - Allow both

        Note that this directive does not give you enough granularity to, say, disable all autoplay videos. Pipe up on the HTML Purifier forums if this is a capability you want.

I first came across them in my referrer logs when tillda asked if anyone could implement an HTML Purifier plugin. This forum thread eventually resulted in the fruition of this plugin that davidm says, "is on top of my favorite list." HTML Purifier goes great with WYSIWYG editors! 1. Credits PaulGregory wrote the overall structure of the code. I added the slashes hack. 2. Install First, you need to place HTML Purifier library somewhere. The code here assumes that you've placed in MODx's assets/plugins/htmlpurifier (no version number). Log into the manager, and navigate: Resources > Manage Resources > Plugins tab > New Plugin Type in a name (probably HTML Purifier), and copy paste this code into the textarea: -------------------------------------------------------------------------------- $e = &$modx->Event; if ($e->name == 'OnBeforeDocFormSave') { global $content; include_once '../assets/plugins/htmlpurifier/library/HTMLPurifier.auto.php'; $purifier = new HTMLPurifier(); static $magic_quotes = null; if ($magic_quotes === null) { // this is an ugly hack because this hook hasn't // had the backslashes removed yet when magic_quotes_gpc is on, // but HTMLPurifier must not have the quotes slashed. $magic_quotes = get_magic_quotes_gpc(); } if ($magic_quotes) $content = stripslashes($content); $content = $purifier->purify($content); if ($magic_quotes) $content = addslashes($content); } -------------------------------------------------------------------------------- Then navigate to the System Events tab and check "OnBeforeDocFormSave". Save the plugin. HTML Purifier now is integrated! 3. Making sure it works You can test HTML Purifier by deliberately putting in crappy HTML and seeing whether or not it gets fixed. A better way is to put in something like this:

              Il est bon

              ...and seeing whether or not the content comes out as:

              Il est bon

              (lang to xml:lang synchronization is one of the many features HTML Purifier has). 4. Caveat Emptor This code does not intercept save requests from the QuickEdit plugin, this may be added in a later version. It also modifies things on save, so there's a slight chance that HTML Purifier may make a boo-boo and accidently mess things up (the original version is not saved). Finally, make sure that MODx is using UTF-8. If you are using, say, a French localisation, you may be using Latin-1, if that's the case, configure HTML Purifier properly like this: $config = HTMLPurifier_Config::createDefault(); $config->set('Core', 'Encoding', 'ISO-8859-1'); // or whatever encoding $purifier = new HTMLPurifier($config); 5. Known Bugs 'rn' characters sometimes mysteriously appear after purification. We are currently investigating this issue. See: 6. See Also A modified version of Jot 1.1.3 is available, which integrates with HTML Purifier. You can check it out here: X.

PREREQUISITES ---------------- This Phorum module only works on PHP5 and with HTML Purifier 4.0.0 or later. 1. UNZIP -------- Unzip phorum-htmlpurifier-x.y.z, producing an htmlpurifier folder. You've already done this step if you're reading this! 2. MOVE ------- Move the htmlpurifier folder to the mods/ folder of your Phorum installation, so the directory structure looks like: phorum/ mods/ htmlpurifier/ INSTALL - this install file info.txt, ... - the module files htmlpurifier/ 3. INSTALL HTML PURIFIER ------------------------ Download and unzip HTML Purifier . Place the contents of the library/ folder in the htmlpurifier/htmlpurifier folder. Your directory structure will look like: phorum/ mods/ htmlpurifier/ htmlpurifier/ HTMLPurifier.auto.php ... - other files HTMLPurifier/ Advanced users: If you have HTML Purifier installed elsewhere on your server, all you need is an HTMLPurifier.auto.php file in the library folder which includes the HTMLPurifier.auto.php file in your install. 4. MIGRATE ---------- If you're setting up a new Phorum installation, all you need to do is create a blank migrate.php file in the htmlpurifier module folder (NOT the library folder. If you have an old Phorum installation and was using BBCode, copy migrate.bbcode.php to migrate.php. If you were using a different input format, follow the instructions in migrate.bbcode.php to create your own custom migrate.php file. Your directory structure should now look like this: phorum/ mods/ htmlpurifier/ migrate.php 5. ENABLE --------- Navigate to your Phorum admin panel at http://example.com/phorum/admin.php, click on Global Settings > Modules, scroll to "HTML Purifier Phorum Mod" and turn it On. 6. MIGRATE SIGNATURES --------------------- If you're setting up a new Phorum installation, skip this step. If you allowed your users to make signatures, navigate to the module settings page of HTML Purifier (Global Settings > Modules > HTML Purifier Phorum Mod > Configure), type in "yes" in the "Confirm" box, and press "Migrate." ONLY DO THIS ONCE! BE SURE TO BACK UP YOUR DATABASE! 7. CONFIGURE ------------ Configure using Edit settings. See that page for more information. vim: et sw=4 sts=4 php-htmlpurifier-4.4.0+dfsg1/plugins/phorum/README010064400000000000000000000043101170566125200166230ustar00 HTML Purifier Phorum Mod - Filter your HTML the Standards-Compliant Way! This Phorum mod enables HTML posting on Phorum. Under normal circumstances, this would cause a huge security risk, but because we are running HTML through HTML Purifier, output is guaranteed to be XSS free and standards-compliant. This mod requires HTML input, and previous markup languages need to be converted accordingly. Thus, it is vital that you create a 'migrate.php' file that works with your installation. If you're using the built-in BBCode formatting, simply move migrate.bbcode.php to that place; for other markup languages, consult said file for instructions on how to adapt it to your needs. -- NOTE ------------------------------------------------- You can also run this module in parallel with another formatting module; this module attempts to place itself at the end of the filtering chain. However, if any previous modules produce insecure HTML (for instance, a JavaScript email obfuscator) they will get cleaned. This module will not work if 'migrate.php' is not created, and an improperly made migration file may *CORRUPT* Phorum, so please take your time to do this correctly. It should go without saying to *BACKUP YOUR DATABASE* before attempting anything here. If no migration is necessary, you can simply create a blank migrate.php file. HTML Purifier is smart and will not re-migrate already processed messages. However, the original code is irretrievably lost (we may change this in the future.) This module will not automatically migrate user signatures, because this process may take a long time. After installing the HTML Purifier module and then configuring 'migrate.php', navigate to Settings and click 'Migrate Signatures' to migrate all user signatures to HTML. All of HTML Purifier's usual functions are configurable via the mod settings page. If you require custom configuration, create config.php file in the mod directory that edits a $config variable. Be sure, also, to set $PHORUM['mod_htmlpurifier']['wysiwyg'] to TRUE if you are using a WYSIWYG editor (you can do this through a common hook or the web configuration form).

        HTML Purifier claims to have a robust yet permissive whitelist: this page will allow you to see precisely what HTML Purifier's internal whitelist is. You can also twiddle with the configuration settings to see how a directive influences the internal workings of the definition objects.

        Modify configuration

        You can specify an array by typing in a comma-separated list of items, HTML Purifier will take care of the rest (including transformation into a real array list or a lookup table).

        render($config, 'HTML'); ?>

        * Some configuration directives make a distinction between an empty variable and a null variable. A whitelist, for example, will take an empty array as meaning no allowed elements, while checking Null/Disabled will mean that user whitelisting functionality is disabled.

        Definitions

        Parent of Fragment
        HTML that HTML Purifier does not live in a void: when it's output, it has to be placed in another element by means of something like <element> <?php echo $html ?> </element>. The parent in this example is element.
        Strict mode
        Whether or not HTML Purifier's output is Transitional or Strict compliant. Non-strict mode still actually a little strict and converts many deprecated elements.
        #PCDATA
        Literally Parsed Character Data, it is regular text. Tags like ul don't allow text in them, so #PCDATA is missing.
        Tag transform
        A tag transform will change one tag to another. Example: font turns into a span tag with appropriate CSS.
        Attr Transform
        An attribute transform changes a group of attributes based on one another. Currently, only lang and xml:lang use this hook, to synchronize each other's values. Pre/Post indicates whether or not the transform is done before/after validation.
        Excludes
        Tags that an element excludes are excluded for all descendants of that element, and not just the children of them.
        Name(Param1, Param2)
        Represents an internal data-structure. You'll have to check out the corresponding classes in HTML Purifier to find out more.

        HTML Purifier XSS Attacks Smoketest

        XSS attacks are from http://ha.ckers.org/xss.html.

        Caveats: Google.com has been programatically disallowed, but as you can see, there are ways of getting around that, so coverage in this area is not complete. Most XSS broadcasts its presence by spawning an alert dialogue. The displayed code is not strictly correct, as linebreaks have been forced for readability. Linewraps have been marked with ». Some tests are omitted for your convenience. Not all control characters are displayed.

This only works in IE and Netscape 8.1+ in IE rendering engine mode. Notice that there is nothing on the page to show that there is included JavaScript. Note: With all of these remote style sheet examples they use the body tag, so it won't work unless there is some content on the page other than the vector itself, so you'll need to add a single letter to the page to make it work if it's an otherwise blank page.

A slight variation on this vector was used to hack Google Desktop http://www.hacker.co.il/security/ie/css_import.html. As a side note you can remote the end STYLE tag if there is HTML immediately after the vector to close it. This is useful if you cannot have either an equal sign or a slash in your cross site scripting attack, which has come up at least once in the real world.

This only works in Opera but is fairly tricky. Setting a link header is not part of the HTTP1.1 spec. However, some browsers still allow it (like Firefox and Opera). The trick here is that I am setting a header (which is basically no different than in the HTTP header saying Link: <http://ha.ckers.org/xss.css>; REL=stylesheet) and the remote style sheet with my cross site scripting vector is running the JavaScript, which is not supported in FireFox.

Even though there is no close > tag the tags below it will close it. A note: this does mess up the HTML, depending on what HTML is beneath it.
