HTML::Parser - HTML parser class
SYNOPSIS
use strict;
use warnings;
use HTML::Parser ();
# Create parser object
my $p = HTML::Parser->new(
api_version => 3,
start_h => [\&start, "tagname, attr"],
end_h => [\&end, "tagname"],
marked_sections => 1,
);
# Parse document text chunk by chunk
$p->parse($chunk1);
$p->parse($chunk2);
# ...
# signal end of document
$p->eof;
# Parse directly from file
$p->parse_file("foo.html");
# or
open(my $fh, "<:utf8", "foo.html") || die;
$p->parse_file($fh);
DESCRIPTION
Objects of the "HTML::Parser" class will recognize markup and separate
it from plain text (alias data content) in HTML documents. As different
kinds of markup and text are recognized, the corresponding event
handlers are invoked.
"HTML::Parser" is not a generic SGML parser. We have tried to make it
able to deal with the HTML that is actually "out there", and it normally
parses as closely as possible to the way the popular web browsers do it
instead of strictly following one of the many HTML specifications from
W3C. Where there is disagreement, there is often an option that you can
enable to get the official behaviour.
The document to be parsed may be supplied in arbitrary chunks. This
makes on-the-fly parsing as documents are received from the network
possible.
If event driven parsing does not feel right for your application, you
might want to use "HTML::PullParser". This is an "HTML::Parser" subclass
that allows a more conventional program structure.
METHODS
The following method is used to construct a new "HTML::Parser" object:
$p = HTML::Parser->new( %options_and_handlers )
This class method creates a new "HTML::Parser" object and returns
it. Key/value argument pairs may be provided to assign event
handlers or initialize parser options. The handlers and parser
options can also be set or modified later by the method calls
described below.
If a top level key is in the form "_h" (e.g., "text_h") then
it assigns a handler to that event, otherwise it initializes a
parser option. The event handler specification value must be an
array reference. Multiple handlers may also be assigned with the
'handlers => [%handlers]' option. See examples below.
If new() is called without any arguments, it will create a parser
that uses callback methods compatible with version 2 of
"HTML::Parser". See the section on "version 2 compatibility" below
for details.
The special constructor option 'api_version => 2' can be used to
initialize version 2 callbacks while still setting other options and
handlers. The 'api_version => 3' option can be used if you don't
want to set any options and don't want to fall back to v2 compatible
mode.
Examples:
$p = HTML::Parser->new(
api_version => 3,
text_h => [ sub {...}, "dtext" ]
);
This creates a new parser object with a text event handler
subroutine that receives the original text with general entities
decoded.
$p = HTML::Parser->new(
api_version => 3,
start_h => [ 'my_start', "self,tokens" ]
);
This creates a new parser object with a start event handler method
that receives the $p and the tokens array.
$p = HTML::Parser->new(
api_version => 3,
handlers => {
text => [\@array, "event,text"],
comment => [\@array, "event,text"],
}
);
This creates a new parser object that stores the event type and the
original text in @array for text and comment events.
The following methods feed the HTML document to the "HTML::Parser"
object:
$p->parse( $string )
Parse $string as the next chunk of the HTML document. Handlers
invoked should not attempt to modify the $string in-place until
$p->parse returns.
If an invoked event handler aborts parsing by calling $p->eof, then
$p->parse() will return a FALSE value. Otherwise the return value is
a reference to the parser object ($p).
$p->parse( $code_ref )
If a code reference is passed as the argument to be parsed, then the
chunks to be parsed are obtained by invoking this function
repeatedly. Parsing continues until the function returns an empty
(or undefined) result. When this happens $p->eof is automatically
signaled.
Parsing will also abort if one of the event handlers calls $p->eof.
The effect of this is the same as:
while (1) {
my $chunk = &$code_ref();
if (!defined($chunk) || !length($chunk)) {
$p->eof;
return $p;
}
$p->parse($chunk) || return undef;
}
But it is more efficient as this loop runs internally in XS code.
$p->parse_file( $file )
Parse text directly from a file. The $file argument can be a
filename, an open file handle, or a reference to an open file
handle.
If $file contains a filename and the file can't be opened, then the
method returns an undefined value and $! tells why it failed.
Otherwise the return value is a reference to the parser object.
If a file handle is passed as the $file argument, then the file will
normally be read until EOF, but not closed.
If an invoked event handler aborts parsing by calling $p->eof, then
$p->parse_file() may not have read the entire file.
On systems with multi-byte line terminators, the values passed for
the offset and length argspecs may be too low if parse_file() is
called on a file handle that is not in binary mode.
If a filename is passed in, then parse_file() will open the file in
binary mode.
$p->eof
Signals the end of the HTML document. Calling the $p->eof method
outside a handler callback will flush any remaining buffered text
(which triggers the "text" event if there is any remaining text).
Calling $p->eof inside a handler will terminate parsing at that
point and cause $p->parse to return a FALSE value. This also
terminates parsing by $p->parse_file().
After $p->eof has been called, the parse() and parse_file() methods
can be invoked to feed new documents with the parser object.
The return value from eof() is a reference to the parser object.
Most parser options are controlled by boolean attributes. Each boolean
attribute is enabled by calling the corresponding method with a TRUE
argument and disabled with a FALSE argument. The attribute value is left
unchanged if no argument is given. The return value from each method is
the old attribute value.
Methods that can be used to get and/or set parser options are:
$p->attr_encoded
$p->attr_encoded( $bool )
By default, the "attr" and @attr argspecs will have general entities
for attribute values decoded. Enabling this attribute leaves
entities alone.
$p->backquote
$p->backquote( $bool )
By default, only ' and " are recognized as quote characters around
attribute values. MSIE also recognizes backquotes for some reason.
Enabling this attribute provides compatibility with this behaviour.
$p->boolean_attribute_value( $val )
This method sets the value reported for boolean attributes inside
HTML start tags. By default, the name of the attribute is also used
as its value. This affects the values reported for "tokens" and
"attr" argspecs.
$p->case_sensitive
$p->case_sensitive( $bool )
By default, tag names and attribute names are down-cased. Enabling
this attribute leaves them as found in the HTML source document.
$p->closing_plaintext
$p->closing_plaintext( $bool )
By default, "plaintext" element can never be closed. Everything up
to the end of the document is parsed in CDATA mode. This historical
behaviour is what at least MSIE does. Enabling this attribute makes
closing " tag effective and the parsing process will
resume after seeing this tag. This emulates early gecko-based
browsers.
$p->empty_element_tags
$p->empty_element_tags( $bool )
By default, empty element tags are not recognized as such and the
"/" before ">" is just treated like a normal name character (unless
"strict_names" is enabled). Enabling this attribute make
"HTML::Parser" recognize these tags.
Empty element tags look like start tags, but end with the character
sequence "/>" instead of ">". When recognized by "HTML::Parser" they
cause an artificial end event in addition to the start event. The
"text" for the artificial end event will be empty and the "tokenpos"
array will be undefined even though the token array will have one
element containing the tag name.
$p->marked_sections
$p->marked_sections( $bool )
By default, section markings like are treated like
ordinary text. When this attribute is enabled section markings are
honoured.
There are currently no events associated with the marked section
markup, but the text can be returned as "skipped_text".
$p->strict_comment
$p->strict_comment( $bool )
By default, comments are terminated by the first occurrence of
"-->". This is the behaviour of most popular browsers (like Mozilla,
Opera and MSIE), but it is not correct according to the official
HTML standard. Officially, you need an even number of "--" tokens
before the closing ">" is recognized and there may not be anything
but whitespace between an even and an odd "--".
The official behaviour is enabled by enabling this attribute.
Enabling of 'strict_comment' also disables recognizing these forms
as comments:
$p->strict_end
$p->strict_end( $bool )
By default, attributes and other junk are allowed to be present on
end tags in a manner that emulates MSIE's behaviour.
The official behaviour is enabled with this attribute. If enabled,
only whitespace is allowed between the tagname and the final ">".
$p->strict_names
$p->strict_names( $bool )
By default, almost anything is allowed in tag and attribute names.
This is the behaviour of most popular browsers and allows us to
parse some broken tags with invalid attribute values like:
By default, "LIST]" is parsed as a boolean attribute, not as part of
the ALT value as was clearly intended. This is also what Mozilla
sees.
The official behaviour is enabled by enabling this attribute. If
enabled, it will cause the tag above to be reported as text since
"LIST]" is not a legal attribute name.
$p->unbroken_text
$p->unbroken_text( $bool )
By default, blocks of text are given to the text handler as soon as
possible (but the parser takes care always to break text at a
boundary between whitespace and non-whitespace so single words and
entities can always be decoded safely). This might create breaks
that make it hard to do transformations on the text. When this
attribute is enabled, blocks of text are always reported in one
piece. This will delay the text event until the following (non-text)
event has been recognized by the parser.
Note that the "offset" argspec will give you the offset of the first
segment of text and "length" is the combined length of the segments.
Since there might be ignored tags in between, these numbers can't be
used to directly index in the original document file.
$p->utf8_mode
$p->utf8_mode( $bool )
Enable this option when parsing raw undecoded UTF-8. This tells the
parser that the entities expanded for strings reported by "attr",
@attr and "dtext" should be expanded as decoded UTF-8 so they end up
compatible with the surrounding text.
If "utf8_mode" is enabled then it is an error to pass strings
containing characters with code above 255 to the parse() method, and
the parse() method will croak if you try.
Example: The Unicode character "\x{2665}" is "\xE2\x99\xA5" when
UTF-8 encoded. The character can also be represented by the entity
"♥" or "♥". If we feed the parser:
$p->parse("\xE2\x99\xA5♥");
then "dtext" will be reported as "\xE2\x99\xA5\x{2665}" without
"utf8_mode" enabled, but as "\xE2\x99\xA5\xE2\x99\xA5" when enabled.
The later string is what you want.
This option is only available with perl-5.8 or better.
$p->xml_mode
$p->xml_mode( $bool )
Enabling this attribute changes the parser to allow some XML
constructs. This enables the behaviour controlled by individually by
the "case_sensitive", "empty_element_tags", "strict_names" and
"xml_pic" attributes and also suppresses special treatment of
elements that are parsed as CDATA for HTML.
$p->xml_pic
$p->xml_pic( $bool )
By default, *processing instructions* are terminated by ">". When
this attribute is enabled, processing instructions are terminated by
"?>" instead.
As markup and text is recognized, handlers are invoked. The following
method is used to set up handlers for different events:
$p->handler( event => \&subroutine, $argspec )
$p->handler( event => $method_name, $argspec )
$p->handler( event => \@accum, $argspec )
$p->handler( event => "" );
$p->handler( event => undef );
$p->handler( event );
This method assigns a subroutine, method, or array to handle an
event.
Event is one of "text", "start", "end", "declaration", "comment",
"process", "start_document", "end_document" or "default".
The "\&subroutine" is a reference to a subroutine which is called to
handle the event.
The $method_name is the name of a method of $p which is called to
handle the event.
The @accum is an array that will hold the event information as
sub-arrays.
If the second argument is "", the event is ignored. If it is undef,
the default handler is invoked for the event.
The $argspec is a string that describes the information to be
reported for the event. Any requested information that does not
apply to a specific event is passed as "undef". If argspec is
omitted, then it is left unchanged.
The return value from $p->handler is the old callback routine or a
reference to the accumulator array.
Any return values from handler callback routines/methods are always
ignored. A handler callback can request parsing to be aborted by
invoking the $p->eof method. A handler callback is not allowed to
invoke the $p->parse() or $p->parse_file() method. An exception will
be raised if it tries.
Examples:
$p->handler(start => "start", 'self, attr, attrseq, text' );
This causes the "start" method of object $p to be called for 'start'
events. The callback signature is "$p->start(\%attr, \@attr_seq,
$text)".
$p->handler(start => \&start, 'attr, attrseq, text' );
This causes subroutine start() to be called for 'start' events. The
callback signature is start(\%attr, \@attr_seq, $text).
$p->handler(start => \@accum, '"S", attr, attrseq, text' );
This causes 'start' event information to be saved in @accum. The
array elements will be ['S', \%attr, \@attr_seq, $text].
$p->handler(start => "");
This causes 'start' events to be ignored. It also suppresses
invocations of any default handler for start events. It is in most
cases equivalent to $p->handler(start => sub {}), but is more
efficient. It is different from the empty-sub-handler in that
"skipped_text" is not reset by it.
$p->handler(start => undef);
This causes no handler to be associated with start events. If there
is a default handler it will be invoked.
Filters based on tags can be set up to limit the number of events
reported. The main bottleneck during parsing is often the huge number of
callbacks made from the parser. Applying filters can improve performance
significantly.
The following methods control filters:
$p->ignore_elements( @tags )
Both the "start" event and the "end" event as well as any events
that would be reported in between are suppressed. The ignored
elements can contain nested occurrences of itself. Example:
$p->ignore_elements(qw(script style));
The "script" and "style" tags will always nest properly since their
content is parsed in CDATA mode. For most other tags
"ignore_elements" must be used with caution since HTML is often not
*well formed*.
$p->ignore_tags( @tags )
Any "start" and "end" events involving any of the tags given are
suppressed. To reset the filter (i.e. don't suppress any "start" and
"end" events), call "ignore_tags" without an argument.
$p->report_tags( @tags )
Any "start" and "end" events involving any of the tags *not* given
are suppressed. To reset the filter (i.e. report all "start" and
"end" events), call "report_tags" without an argument.
Internally, the system has two filter lists, one for "report_tags" and
one for "ignore_tags", and both filters are applied. This effectively
gives "ignore_tags" precedence over "report_tags".
Examples:
$p->ignore_tags(qw(style));
$p->report_tags(qw(script style));
results in only "script" events being reported.
Argspec
Argspec is a string containing a comma-separated list that describes the
information reported by the event. The following argspec identifier
names can be used:
"attr"
Attr causes a reference to a hash of attribute name/value pairs to
be passed.
Boolean attributes' values are either the value set by
$p->boolean_attribute_value, or the attribute name if no value has
been set by $p->boolean_attribute_value.
This passes undef except for "start" events.
Unless "xml_mode" or "case_sensitive" is enabled, the attribute
names are forced to lower case.
General entities are decoded in the attribute values and one layer
of matching quotes enclosing the attribute values is removed.
The Unicode character set is assumed for entity decoding.
@attr
Basically the same as "attr", but keys and values are passed as
individual arguments and the original sequence of the attributes is
kept. The parameters passed will be the same as the @attr calculated
here:
@attr = map { $_ => $attr->{$_} } @$attrseq;
assuming $attr and $attrseq here are the hash and array passed as
the result of "attr" and "attrseq" argspecs.
This passes no values for events besides "start".
"attrseq"
Attrseq causes a reference to an array of attribute names to be
passed. This can be useful if you want to walk the "attr" hash in
the original sequence.
This passes undef except for "start" events.
Unless "xml_mode" or "case_sensitive" is enabled, the attribute
names are forced to lower case.
"column"
Column causes the column number of the start of the event to be
passed. The first column on a line is 0.
"dtext"
Dtext causes the decoded text to be passed. General entities are
automatically decoded unless the event was inside a CDATA section or
was between literal start and end tags ("script", "style", "xmp",
"iframe", "title", "textarea" and "plaintext").
The Unicode character set is assumed for entity decoding. With Perl
version 5.6 or earlier only the Latin-1 range is supported, and
entities for characters outside the range 0..255 are left unchanged.
This passes undef except for "text" events.
"event"
Event causes the event name to be passed.
The event name is one of "text", "start", "end", "declaration",
"comment", "process", "start_document" or "end_document".
"is_cdata"
Is_cdata causes a TRUE value to be passed if the event is inside a
CDATA section or between literal start and end tags ("script",
"style", "xmp", "iframe", "title", "textarea" and "plaintext").
if the flag is FALSE for a text event, then you should normally
either use "dtext" or decode the entities yourself before the text
is processed further.
"length"
Length causes the number of bytes of the source text of the event to
be passed.
"line"
Line causes the line number of the start of the event to be passed.
The first line in the document is 1. Line counting doesn't start
until at least one handler requests this value to be reported.
"offset"
Offset causes the byte position in the HTML document of the start of
the event to be passed. The first byte in the document has offset 0.
"offset_end"
Offset_end causes the byte position in the HTML document of the end
of the event to be passed. This is the same as "offset" + "length".
"self"
Self causes the current object to be passed to the handler. If the
handler is a method, this must be the first element in the argspec.
An alternative to passing self as an argspec is to register closures
that capture $self by themselves as handlers. Unfortunately this
creates circular references which prevent the HTML::Parser object
from being garbage collected. Using the "self" argspec avoids this
problem.
"skipped_text"
Skipped_text returns the concatenated text of all the events that
have been skipped since the last time an event was reported. Events
might be skipped because no handler is registered for them or
because some filter applies. Skipped text also includes marked
section markup, since there are no events that can catch it.
If an ""-handler is registered for an event, then the text for this
event is not included in "skipped_text". Skipped text both before
and after the ""-event is included in the next reported
"skipped_text".
"tag"
Same as "tagname", but prefixed with "/" if it belongs to an "end"
event and "!" for a declaration. The "tag" does not have any prefix
for "start" events, and is in this case identical to "tagname".
"tagname"
This is the element name (or *generic identifier* in SGML jargon)
for start and end tags. Since HTML is case insensitive, this name is
forced to lower case to ease string matching.
Since XML is case sensitive, the tagname case is not changed when
"xml_mode" is enabled. The same happens if the "case_sensitive"
attribute is set.
The declaration type of declaration elements is also passed as a
tagname, even if that is a bit strange. In fact, in the current
implementation tagname is identical to "token0" except that the name
may be forced to lower case.
"token0"
Token0 causes the original text of the first token string to be
passed. This should always be the same as $tokens->[0].
For "declaration" events, this is the declaration type.
For "start" and "end" events, this is the tag name.
For "process" and non-strict "comment" events, this is everything
inside the tag.
This passes undef if there are no tokens in the event.
"tokenpos"
Tokenpos causes a reference to an array of token positions to be
passed. For each string that appears in "tokens", this array
contains two numbers. The first number is the offset of the start of
the token in the original "text" and the second number is the length
of the token.
Boolean attributes in a "start" event will have (0,0) for the
attribute value offset and length.
This passes undef if there are no tokens in the event (e.g., "text")
and for artificial "end" events triggered by empty element tags.
If you are using these offsets and lengths to modify "text", you
should either work from right to left, or be very careful to
calculate the changes to the offsets.
"tokens"
Tokens causes a reference to an array of token strings to be passed.
The strings are exactly as they were found in the original text, no
decoding or case changes are applied.
For "declaration" events, the array contains each word, comment, and
delimited string starting with the declaration type.
For "comment" events, this contains each sub-comment. If
$p->strict_comments is disabled, there will be only one sub-comment.
For "start" events, this contains the original tag name followed by
the attribute name/value pairs. The values of boolean attributes
will be either the value set by $p->boolean_attribute_value, or the
attribute name if no value has been set by
$p->boolean_attribute_value.
For "end" events, this contains the original tag name (always one
token).
For "process" events, this contains the process instructions (always
one token).
This passes "undef" for "text" events.
"text"
Text causes the source text (including markup element delimiters) to
be passed.
"undef"
Pass an undefined value. Useful as padding where the same handler
routine is registered for multiple events.
'...'
A literal string of 0 to 255 characters enclosed in single (') or
double (") quotes is passed as entered.
The whole argspec string can be wrapped up in '@{...}' to signal that
the resulting event array should be flattened. This only makes a
difference if an array reference is used as the handler target. Consider
this example:
$p->handler(text => [], 'text');
$p->handler(text => [], '@{text}']);
With two text events; "foo", "bar"; then the first example will end up
with [["foo"], ["bar"]] and the second with ["foo", "bar"] in the
handler target array.
Events
Handlers for the following events can be registered:
"comment"
This event is triggered when a markup comment is recognized.
Example:
"declaration"
This event is triggered when a *markup declaration* is recognized.
For typical HTML documents, the only declaration you are likely to
find is .
Example:
DTDs inside will confuse HTML::Parser.
"default"
This event is triggered for events that do not have a specific
handler. You can set up a handler for this event to catch stuff you
did not want to catch explicitly.
"end"
This event is triggered when an end tag is recognized.
Example:
"end_document"
This event is triggered when $p->eof is called and after any
remaining text is flushed. There is no document text associated with
this event.
"process"
This event is triggered when a processing instructions markup is
recognized.
The format and content of processing instructions are system and
application dependent.
Examples:
"start"
This event is triggered when a start tag is recognized.
Example:
"start_document"
This event is triggered before any other events for a new document.
A handler for it can be used to initialize stuff. There is no
document text associated with this event.
"text"
This event is triggered when plain text (characters) is recognized.
The text may contain multiple lines. A sequence of text may be
broken between several text events unless $p->unbroken_text is
enabled.
The parser will make sure that it does not break a word or a
sequence of whitespace between two text events.
Unicode
"HTML::Parser" can parse Unicode strings when running under perl-5.8 or
better. If Unicode is passed to $p->parse() then chunks of Unicode will
be reported to the handlers. The offset and length argspecs will also
report their position in terms of characters.
It is safe to parse raw undecoded UTF-8 if you either avoid decoding
entities and make sure to not use *argspecs* that do, or enable the
"utf8_mode" for the parser. Parsing of undecoded UTF-8 might be useful
when parsing from a file where you need the reported offsets and lengths
to match the byte offsets in the file.
If a filename is passed to $p->parse_file() then the file will be read
in binary mode. This will be fine if the file contains only ASCII or
Latin-1 characters. If the file contains UTF-8 encoded text then care
must be taken when decoding entities as described in the previous
paragraph, but better is to open the file with the UTF-8 layer so that
it is decoded properly:
open(my $fh, "<:utf8", "index.html") || die "...: $!";
$p->parse_file($fh);
If the file contains text encoded in a charset besides ASCII, Latin-1 or
UTF-8 then decoding will always be needed.
VERSION 2 COMPATIBILITY
When an "HTML::Parser" object is constructed with no arguments, a set of
handlers is automatically provided that is compatible with the old
HTML::Parser version 2 callback methods.
This is equivalent to the following method calls:
$p->handler(start => "start", "self, tagname, attr, attrseq, text");
$p->handler(end => "end", "self, tagname, text");
$p->handler(text => "text", "self, text, is_cdata");
$p->handler(process => "process", "self, token0, text");
$p->handler(
comment => sub {
my($self, $tokens) = @_;
for (@$tokens) {$self->comment($_);}
},
"self, tokens"
);
$p->handler(
declaration => sub {
my $self = shift;
$self->declaration(substr($_[0], 2, -1));
},
"self, text"
);
Setting up these handlers can also be requested with the "api_version =>
2" constructor option.
SUBCLASSING
The "HTML::Parser" class is able to be subclassed. Parser objects are
plain hashes and "HTML::Parser" reserves only hash keys that start with
"_hparser". The parser state can be set up by invoking the init()
method, which takes the same arguments as new().
EXAMPLES
The first simple example shows how you might strip out comments from an
HTML document. We achieve this by setting up a comment handler that does
nothing and a default handler that will print out anything else:
use HTML::Parser;
HTML::Parser->new(
default_h => [sub { print shift }, 'text'],
comment_h => [""],
)->parse_file(shift || die) || die $!;
An alternative implementation is:
use HTML::Parser;
HTML::Parser->new(
end_document_h => [sub { print shift }, 'skipped_text'],
comment_h => [""],
)->parse_file(shift || die) || die $!;
This will in most cases be much more efficient since only a single
callback will be made.
The next example prints out the text that is inside the element
of an HTML document. Here we start by setting up a start handler. When
it sees the title start tag it enables a text handler that prints any
text found and an end handler that will terminate parsing as soon as the
title end tag is seen:
use HTML::Parser ();
sub start_handler {
return if shift ne "title";
my $self = shift;
$self->handler(text => sub { print shift }, "dtext");
$self->handler(
end => sub {
shift->eof if shift eq "title";
},
"tagname,self"
);
}
my $p = HTML::Parser->new(api_version => 3);
$p->handler(start => \&start_handler, "tagname,self");
$p->parse_file(shift || die) || die $!;
print "\n";
More examples are found in the eg/ directory of the "HTML-Parser"
distribution: the program "hrefsub" shows how you can edit all links
found in a document; the program "htextsub" shows how to edit the text
only; the program "hstrip" shows how you can strip out certain
tags/elements and/or attributes; and the program "htext" show how to
obtain the plain text, but not any script/style content.
You can browse the eg/ directory online from the *[Browse]* link on the
http://search.cpan.org/~gaas/HTML-Parser/ page.
BUGS
The <style> and <script> sections do not end with the first "</", but
need the complete corresponding end tag. The standard behaviour is not
really practical.
When the *strict_comment* option is enabled, we still recognize comments
where there is something other than whitespace between even and odd "--"
markers.
Once $p->boolean_attribute_value has been set, there is no way to
restore the default behaviour.
There is currently no way to get both quote characters into the same
literal argspec.
Empty tags, e.g. "<>" and "</>", are not recognized. SGML allows them to
repeat the previous start tag or close the previous start tag
respectively.
NET tags, e.g. "code/.../" are not recognized. This is SGML shorthand
for "<code>...</code>".
Incomplete start or end tags, e.g. "<tt<b>...</b</tt>" are not
recognized.
DIAGNOSTICS
The following messages may be produced by HTML::Parser. The notation in
this listing is the same as used in perldiag:
Not a reference to a hash
(F) The object blessed into or subclassed from HTML::Parser is not a
hash as required by the HTML::Parser methods.
Bad signature in parser state object at %p
(F) The _hparser_xs_state element does not refer to a valid state
structure. Something must have changed the internal value stored in
this hash element, or the memory has been overwritten.
_hparser_xs_state element is not a reference
(F) The _hparser_xs_state element has been destroyed.
Can't find '_hparser_xs_state' element in HTML::Parser hash
(F) The _hparser_xs_state element is missing from the parser hash.
It was either deleted, or not created when the object was created.
API version %s not supported by HTML::Parser %s
(F) The constructor option 'api_version' with an argument greater
than or equal to 4 is reserved for future extensions.
Bad constructor option '%s'
(F) An unknown constructor option key was passed to the new() or
init() methods.
Parse loop not allowed
(F) A handler invoked the parse() or parse_file() method. This is
not permitted.
marked sections not supported
(F) The $p->marked_sections() method was invoked in a HTML::Parser
module that was compiled without support for marked sections.
Unknown boolean attribute (%d)
(F) Something is wrong with the internal logic that set up aliases
for boolean attributes.
Only code or array references allowed as handler
(F) The second argument for $p->handler must be either a subroutine
reference, then name of a subroutine or method, or a reference to an
array.
No handler for %s events
(F) The first argument to $p->handler must be a valid event name;
i.e. one of "start", "end", "text", "process", "declaration" or
"comment".
Unrecognized identifier %s in argspec
(F) The identifier is not a known argspec name. Use one of the names
mentioned in the argspec section above.
Literal string is longer than 255 chars in argspec
(F) The current implementation limits the length of literals in an
argspec to 255 characters. Make the literal shorter.
Backslash reserved for literal string in argspec
(F) The backslash character "\" is not allowed in argspec literals.
It is reserved to permit quoting inside a literal in a later
version.
Unterminated literal string in argspec
(F) The terminating quote character for a literal was not found.
Bad argspec (%s)
(F) Only identifier names, literals, spaces and commas are allowed
in argspecs.
Missing comma separator in argspec
(F) Identifiers in an argspec must be separated with ",".
Parsing of undecoded UTF-8 will give garbage when decoding entities
(W) The first chunk parsed appears to contain undecoded UTF-8 and
one or more argspecs that decode entities are used for the callback
handlers.
The result of decoding will be a mix of encoded and decoded
characters for any entities that expand to characters with code
above 127. This is not a good thing.
The recommended solution is to apply Encode::decode_utf8() on the
data before feeding it to the $p->parse(). For $p->parse_file() pass
a file that has been opened in ":utf8" mode.
The alternative solution is to enable the "utf8_mode" and not decode
before passing strings to $p->parse(). The parser can process raw
undecoded UTF-8 sanely if the "utf8_mode" is enabled, or if the
"attr", @attr or "dtext" argspecs are avoided.
Parsing string decoded with wrong endian selection
(W) The first character in the document is U+FFFE. This is not a
legal Unicode character but a byte swapped "BOM". The result of
parsing will likely be garbage.
Parsing of undecoded UTF-32
(W) The parser found the Unicode UTF-32 "BOM" signature at the start
of the document. The result of parsing will likely be garbage.
Parsing of undecoded UTF-16
(W) The parser found the Unicode UTF-16 "BOM" signature at the start
of the document. The result of parsing will likely be garbage.

3.57 2008-11-16
* The <iframe> element content is now parsed in literal mode.

* Test and documentation tweaks from Alex Kapranoff.
3.56 2007-01-12
* Cloning of parser state for compatibility with threads.

<http://rt.cpan.org/Ticket/Display.html?id=20864>
3.55 2006-07-10
* Treat <> at the end of document as text. Used to be
reported as a comment.
* Improved Firefox compatibility for bad HTML:
- Unclosed <script>, <style> are now treated as empty tags.
- Unclosed <textarea>, <xmp> and <plaintext> treat rest as text.
- Unclosed <title> closes at next tag.
* Make <!a'b> a comment by itself.
3.54 2006-04-28
* Yaakov Belch discovered yet another issue with <script> parsing.
Enabling of 'empty_element_tags' got the parser confused
if it found such a tag for elements that are normally parsed
in literal mode. Of these <script src="..."/> is the only
one likely to be found in documents.
<http://rt.cpan.org//Ticket/Display.html?id=18965>
3.53 2006-04-27
* When ignore_element was enabled it got confused if the
corresponding tags did not nest properly; the end tag
was treated it as if it was a start tag.
Found and fixed by Yaakov Belch <code@yaakovnet.net>.
<http://rt.cpan.org/Ticket/Display.html?id=18936>
3.52 2006-04-26
* Make sure the 'start_document' fires exactly once for
each document parsed. For earlier releases it did not
fire at all for empty documents and could fire multiple
times if parse was called with empty chunks.
* Documentation tweaks and typo fixes.
3.51 2006-03-22
* Named entities outside the Latin-1 range are now only expanded
when properly terminated with ";". This makes HTML::Parser
compatible with Firefox/Konqueror/MSIE when it comes to how these
entities are expanded in attribute values. Firefox does expand
unterminated non-Latin-1 entities in plain text, so here
HTML::Parser only stays compatible with Konqueror/MSIE.
Fixes <http://rt.cpan.org/Ticket/Display.html?id=17962>.
* Fixed some documentation typos spotted by <william@knowmad.com>.
<http://rt.cpan.org/Ticket/Display.html?id=18062>
3.50 2006-02-14
* The 3.49 release didn't compile with VC++ because it mixed code
and declarations. Fixed by Steve Hay <steve.hay@uk.radan.com>.
3.49 2006-02-08
* Events could sometimes still fire after a handler has signaled eof.
* Marked_sections with text ending in square bracket parsed wrong.
Fix provided by <paul.bijnens@xplanation.com>.
<http://rt.cpan.org/Ticket/Display.html?id=16749>
3.48 2005-12-02
* Enabling empty_element_tags by default for HTML::TokeParser
was a mistake. Reverted that change.
<http://rt.cpan.org/Ticket/Display.html?id=16164>
* When processing a document with "marked_sections => 1", the
skipped text missed the first 3 bytes "<![".
<http://rt.cpan.org/Ticket/Display.html?id=16207>
3.47 2005-11-22
* Added empty_element_tags and xml_pic configuration
options. These make it possible to enable these XML
features without enabling the full XML-mode.
* The empty_element_tags is enabled by default for
HTML::TokeParser.
3.46 2005-10-24
* Don't try to treat an literal as space.
This breaks Unicode parsing.
<http://rt.cpan.org/Ticket/Display.html?id=15068>
* The unbroken_text option is now on by default
for HTML::TokeParser.
* HTML::Entities::encode will now encode "'" by default.
* Improved report/ignore_tags documentation by
Norbert Kiesel <nkiesel@tbdnetworks.com>.
* Test suite now use Test::More, by
Norbert Kiesel <nkiesel@tbdnetworks.com>.
* Fix HTML::Entities typo spotted by
Stefan Funke <bundy@adm.arcor.net>.
* Faster load time with XSLoader (perl-5.6 or better now required).
* Fixed POD markup errors in some of the modules.
3.45 2005-01-06
* Fix stack memory leak caused by missing PUTBACK. Only
code that used $p->parse(\&cb) form was affected.
Fix provided by Gurusamy Sarathy <gsar@sophos.com>.
3.44 2004-12-28
* Fix confusion about nested quotes in <script> and <style> text.
3.43 2004-12-06
* The SvUTF8 flag was not propagated correctly when replacing
unterminated entities.
* Fixed test failure because of missing binmode on Windows.
3.42 2004-12-04
* Avoid sv_catpvn_utf8_upgrade() as that macro was not
available in perl-5.8.0.
Patch by Reed Russell <Russell.Reed@acxiom.com>.
* Add casts to suppress compilation warnings for char/U8
mismatches.
* HTML::HeadParser will always push new header values.
This make sure we never loose old header values.
3.41 2004-11-30
* Fix unresolved symbol error with perl-5.005.
3.40 2004-11-29
* Make utf8_mode only available on perl-5.8 or better. It produced
garbage with older versions of perl.
* Emit warning if entities are decoded and something in the first
chunk looks like hi-bit UTF-8. Previously this warning was only
triggered for documents with BOM.
3.39_92 2004-11-23
* More documentation of the Unicode issues. Moved around HTML::Parser
documentation a bit.
* New boolean option; $p->utf8_mode to allow parsing of raw UTF-8.
* Documented that HTML::Entities::decode_entities() can take multiple
arguments.
* Unterminated entities are now decoded in text (compatibility
with MSIE misfeature).
* Document HTML::Entities::_decode_entities(); this variation of the
decode_entities() function has been available for a long time, but
have not been documented until now.
* HTML::Entities::_decode_entities() can now be told to try to
expand unterminated entities.
* Simplified Makefile.PL
3.39_91 2004-11-23
* The HTML::HeadParser will skip Unicode BOM. Previously it
would consider the <head> section done when it saw the BOM.
* The parser will look for Unicode BOM and give appropriate
warnings if the form found indicate trouble.
* If no matching end tag is found for <script>, <style>, <xmp>
<title>, <textarea> then generate one where the next tag
starts.
* For <script> and <style> recognize quoted strings and don't
consider end element if the corresponding end tag is found
inside such a string.
3.39_90 2004-11-17
* The <title> element is now parsed in literal mode, which
means that other tags are not recognized until has
been seen.
* Unicode support for perl-5.8 and better.
* Decoding Unicode entities always enabled; no longer a compile
time option.
* Propagation of UTF8 state on strings.
Patch contributed by John Gardiner Myers .
* Calculate offsets and lengths in chars for Unicode strings.
* Fixed link typo in the HTML::TokeParser documentation.
3.38 2004-11-11
* New boolean option; $p->closing_plaintext
Contributed by Alex Kapranoff
3.37 2004-11-10
* Improved handling of HTML encoded surrogate pairs and illegally
encoded Unicode; .
Patch by John Gardiner Myers .
* Avoid generating bad UTF8 strings when decoding entities
representing chars beyond #255 in 8-bit strings. Such bad
UTF8 sometimes made perl-5.8.5 and older segfault.
* Undocument v2 style subclassing in synopsis section.
* Internal cleanup: Make 'gcc -Wall' happier.
* Avoid modification of PVs during parsing of attrspec.
Another patch by John Gardiner Myers.
3.36 2004-04-01
* Improved MSIE/Mozilla compatibility. If the same attribute
name repeats for a start tag, use the first value instead
of the last. Patch by Nick Duffek .
3.35 2003-12-12
* Documentation fixes by Paul Croome .
* Removed redundant dSP.
3.34 2003-10-27
* Fix segfault that happened when the parse callback caused
the stack to get reallocated. The original bug report was
3.33 2003-10-14
* Perl 5.005 or better is now required. For some reason we get
a test failure with perl-5.004 and I don't really feel like
debugging that perl any more. Details about this failure can
be found at .
* New HTML::TokeParser method called 'get_phrase'. It returns
all current text while ignoring any phrase-level markup.
* The HTML::TokeParser method 'get_text' now expands skipped
non-phrase-level tags as a single space.
3.32 2003-10-10
* If the document parsed ended with some kind of unterminated markup,
then the parser state was not reset properly and this piece of markup
would show up in the beginning of the next document parsed.
* The get_text and get_trimmed_text methods of HTML::TokeParser can
now take multiple end tags as argument. Patch by
at .
* Various documentation tweaks.
* Included another example program: hdump
3.31 2003-08-19
* The -DDEBUGGING fix in 3.30 was not really there :-(
3.30 2003-08-17
* The previous release failed to compile on a -DDEBUGGING perl
like the one provided by Redhat 9.
* Got rid of references to perl-5.7.
* Further fixes to avoid warnings from Visual C.
Patch by Steve Hay .
3.29 2003-08-14
* Setting xml_mode now implies strict_names also for end tags.
* Avoid warning from Visual C. Patch by .
* 64-bit fix from Doug Larrick
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=195500
* Try to parse similar to Mozilla/MSIE in certain edge cases.
All these are outside of the official definition of HTML but
HTML spam often tries to take advantage of these.
- New configuration attribute 'strict_end'. Unless enabled
we will allow end tags to contain extra words or stuff
that look like attributes before the '>'. This means that
tags like these:
" ignored>
are now all parsed as a 'foo' end tag instead of text.
Even if the extra stuff looks like attributes they will not
be reported if requested via the 'attr' or 'tokens' argspecs
for the 'end' handler.
- Parse '' and '' as comments unless
strict_comment is enabled. Previous versions of the parser
would report these as text. If these comments contain
quoted words prefixed by space or '=' these words can
contain '>' without terminating the comment.
- Parse '" foo>' as comment containing ' "<>" foo'.
Previous versions of the parser would terminate the comment
at the first '>' and report the rest as text.
- Legacy comment mode: Parse with comments terminated with a
lone '>' if no '-->' is found before eof.
- Incomplete tag at eof is reported as a 'comment' instead
of 'text' unless strict_comment is enabled.
3.28 2003-04-16
* When 'strict_comment' is off (which it is by default)
treat anything that matches a comment.
* Should now be more efficient on threaded perls.
3.27 2003-01-18
* Typo fixes to the documentation.
* HTML::Entities::escape_entities_numeric contributed
by Sean M. Burke .
* Included one more example program 'hlc' that show
how to downcase all tags in an HTML file.
3.26 2002-03-17
* Avoid core dump in some cases where the callback croaks.
The perl_call_method and perl_call_sv needs G_EVAL flag
to be safe.
* New parser attributes; 'attr_encoded' and 'case_sensitive'.
Contributed by Guy Albertelli II .
* HTML::Entities
- don't encode \r by default as suggested by Sean M. Burke.
* HTML::HeadParser
- ignore empty http-equiv
- allow multiple elements. Patch by
Timur I. Bakeyev
* Avoid warnings from bleadperl on the uentities test.
3.25 2001-05-11
* Minor tweaks for build failures on perl5.004_04, perl-5.6.0,
and for macro clash under Windows.
* Improved parsing of <![CDATA[... :-)
3.24 2001-05-09
* $p->parse(CODE)
* New events: start_document, end_document
* New argspecs: skipped_text, offset_end
* The offset/line/column counters was not properly reset
after eof.
3.23 2001-05-01
* If the $p->ignore_elements filter did not work as it should if
handlers for start/end events was not registered.
3.22 2001-04-17
* The <textarea> element is now parsed in literal mode, i.e. no other tags
recognized until the </textarea> tag is seen. Unlike other literal elements,
the text content is not 'cdata'.
* The XML ' entity is decoded. It apos-char itself is still encoded as
' as ' is not really an HTML tag, and not recognized by many HTML
browsers.
3.21 2001-04-10
* Fix a memory leak which occurred when using filter methods.
* Avoid a few compiler warnings (DEC C):
- Trailing comma found in enumerator list
- "unsigned char" is not compatible with "const char".
* Doc update.
3.20 2001-04-02
* Some minor documentation updates.
3.19_94 2001-03-30
* Implemented 'tag', 'line', 'column' argspecs.
* HTML::PullParser doc update.
eg/hform is an example of HTML::PullParser usage.
3.19_93 2001-03-27
* Shorten 'report_only_tags' to 'report_tags'.
I think it reads better.
* Bleadperl portability fixes.
3.19_92 2001-03-25
* HTML::HeadParser made more efficient by using 'ignore_elements'.
* HTML::LinkExtor made more efficient by using 'report_only_tags'.
* HTML::TokeParser generalized into HTML::PullParser. HTML::PullParser
only support the get_token/unget_token interface of HTML::TokeParser,
but is more flexible because the information that make up an token
is customisable. HTML::TokeParser is made into an HTML::PullParser
subclass.
3.19_91 2001-03-19
* Array references can be passed to the filter methods. Makes it easier
to use them as constructor options.
* Example programs updated to use filters.
* Reset ignored_element state on EOF.
* Documentation updates.
* The netscape_buggy_comment() method now generates mandatory warning
about its deprecation.
3.19_90 2001-03-13
* This is an developer only release. It contains some new
experimental features. The interface to these might still change.
* Implemented filters to reduce the numbers of callbacks generated:
- $p->ignore_tags()
- $p->report_only_tags()
- $p->ignore_elements()
* New @attr argspec. Less overhead than 'attr' and allow
compatibility with XML::Parser style start events.
* The whole argspec can be wrapped up in @{...} to signal
flattening. Only makes a difference when the target is an
array.
3.19 2001-03-09
* Avoid the entity2char global. That should make the module
more thread safe. Patch by Gurusamy Sarathy <gsar@ActiveState.com>.
3.18 2001-02-24
* There was a C++ style comment left in util.c. Strict C
compilers do not like that kind of stuff.
3.17 2001-02-23
* The 3.16 release broke MULTIPLICITY builds. Fixed.
3.16 2001-02-22
* The unbroken_text option now works across ignored tags.
* Fix casting of pointers on some 64 bit platforms.
* Fix decoding of Unicode entities. Only optionally available for
perl-5.7.0 or better.
* Expose internal decode_entities() function at the Perl level.
* Reindented some code.
3.15 2000-12-26
* HTML::TokeParser's get_tag() method now takes multiple
tags to match. Hopefully the documentation is also a bit clearer.
* #define PERL_NO_GET_CONTEXT: Should speed up things for thread
enabled versions of perl.
* Quote some more entities that also happens to be perl keywords.
This avoids warnings on perl-5.004.
* Unicode entities only triggered for perl-5.7.0 or higher.
3.14 2000-12-03
* If a handler triggered by flushing text at eof called the
eof method then infinite recursion occurred. Fixed.
Bug discovered by Jonathan Stowe <gellyfish@gellyfish.com>.
* Allow <!doctype ...> to be parsed as declaration.
3.13 2000-09-17
* Experimental support for decoding of Unicode entities.
3.12 2000-09-14
* Some tweaks to get it to compile with "Optimierender Microsoft (R)
32-Bit C/C++-Compiler, Version 12.00.8168, fuer x86."
Patch by Matthias Waldorf <matthias.waldorf@zoom.de>.
* HTML::Entities documentation spelling patch by
David Dyck <dcd@tc.fluke.com>.
3.11 2000-08-22
* HTML::LinkExtor and eg/hrefsub now obtain %linkElements from
the HTML::Tagset module.
3.10 2000-06-29
* Avoid core dump when stack gets relocated as the result of
text handler invocation while $p->unbroken_text is enabled.
Needed to refresh the stack pointer.
3.09 2000-06-28
* Avoid core dump if somebody clobbers the aliased $self argument of
a handler.
* HTML::TokeParser documentation update suggested by
Paul Makepeace <Paul.Makepeace@realprogrammers.com>.
3.08 2000-05-23
* Fix core dump for large start tags.
Bug spotted by Alexander Fraser <green795@hotmail.com>
* Added yet another example program: eg/hanchors
* Typo fix by Jamie McCarthy <jamie@mccarthy.org>
3.07 2000-03-20
* Fix perl5.004 builds (was broken in 3.06)
* Declaration parsing mode now only triggers for <!DOCTYPE ...> and
<!ENTITY ...>. Based on patch by la mouton <kero@3sheep.com>.
3.06 2000-03-06
* Multi-threading/MULTIPLICITY compilation fix.
Both Doug MacEachern <dougm@pobox.com> and
Matthias Urlichs <smurf@noris.net> provided a patch.
* Avoid some "statement not reached" warnings from picky
compilers.
* Remove final commas in enums as ANSI C does not allow
them and some compilers actually care.
Patch by James Walden <jamesw@ichips.intel.com>
* Added eg/htextsub example program.
3.05 2000-01-22
* Implemented $p->unbroken_text option
* Don't parse content of certain HTML elements as CDATA when
xml_mode is enabled.
* Offset was reported with wrong sign for text at end of chunk.
3.04 2000-01-15
* Backed out 3.03-patch that checked for legal handler and attribute
names in the HTML::Parser constructor.
* Documentation typo fixed by Michael.
3.03 2000-01-14
* We did not get out of comment mode for comments ending with an
odd number of "-" before ">". Patch by la mouton <kero@3sheep.com>
* Documentation patch by Michael.
3.02 1999-12-21
* Hide ~-magic IV-pointer to 'struct p_state' behind a reference.
This allow copying of the internal _hparser_xs_state element, and
will make HTML-Tree-0.61 work again.
* Introduced $p->init() which might be useful for subclasses that
only want the initialization part of the constructor.
* Filled out DIAGNOSTICS section of the HTML::Parser POD.
3.01 1999-12-19
* Rely on ~-magic instead of a DESTROY method to deallocate
the internal 'struct p_state'. This avoid memory leaks
when people simply wipe of the content of the object hash.
* One of the assertion in hparser.c had opposite logic. This made
the parser fail when compiled with a -DDEBUGGING perl.
* Don't assume any specific order of hash keys in the t/cases.t.
This test failed with some newer development releases of perl.
3.00 1999-12-14
* Documentation update (most of it from Michael)
* Minor patch to eg/hstrip so that it use a "" handler
instead of &ignore.
* Test suite patches from Michael
2.99_96 1999-12-13
* Patches from Michael:
- A handler of "" means that the event will be ignored.
More efficient than using 'sub {}' as handler.
- Don't use a perl hash for looking up argspec keywords.
- Documentation tweaks.
2.99_95 1999-12-09
* (this is a 3.00 candidate)
* Fixed core dump when "<" was followed by an 8-bit character.
Spotted and test case provided by Doug MacEachern. Doug had
been running HTML-Parser-XS through more that 1 million urls that
had been downloaded via LWP.
* Handlers can now invoke $p->eof to request the parsing to terminate.
HTML::HeadParser has been simplified by taking advantage of this.
Also added a title-extraction example that uses this.
* Michael once again fixed my bad English in the HTML::Parser
documentation.
* netscape_buggy_comment will carp instead of warn
* updated TODO/README
* Documented that HTML::Filter is depreciated.
* Made backslash reserved in literal argspec strings.
* Added several new test scripts.
2.99_94 1999-12-08
* (should almost be a 3.00 candidate)
* Renamed 'cdata_flag' as 'is_cdata'.
* Dropped support for wrapping callback handler and argspec
in an array and passing a reference to $p->handler. It
created ambiguities when you want to pass a array as
handler destination and not update argspec. The wrapping
for constructor arguments are unchanged.
* Reworked the documentation after updates from Michael.
* Simplified internal check_handler(). It should probably simply
be inlined in handler() again.
* Added argspec 'length' and 'undef'
* Fix statement-less label. Fix suggested by Matthew Langford
<langfml@Eng.Auburn.EDU>.
* Added two more example programs: eg/hstrip and eg/htext.
* Various minor patches from Michael.
2.99_93 1999-12-07
* Documentation update
* $p->bool_attr_value renamed as $p->boolean_attribute_value
* Internal renaming: attrspec --> argspec
* Introduced internal 'enum argcode' in hparser.c
* Added eg/hrefsub
2.99_92 1999-12-05
* More documentation patches from Michael
* Renamed 'token1' as 'token0' as suggested by Michael
* For artificial end tags we now report 'tokens', but not 'tokenpos'.
* Boolean attribute values show up as (0, 0) in 'tokenpos' now.
* If $p->bool_attr_value is set it will influence 'tokens'
* Fix for core dump when parsing <a "> when $p->strict_names(0).
Based on fix by Michael.
* Will av_extend() the tokens/tokenspos arrays.
* New test suite script by Michael: t/attrspec.t
2.99_91 1999-12-04
* Implemented attrspec 'offset'
* Documentation patch from Michael
* Some more cleanup/updated TODO
2.99_90 1999-12-03
* (first beta for 3.00)
* Using "realloc" as a parameter name in grow_tokens created
problems for some people. Fix by Paul Schinder <schinder@pobox.com>
* Patch by Michael that makes array handler destinations really work.
* Patch by Michael that make HTML::TokeParser use this. This gave a
a speedup of about 80%.
* Patch by Michael that makes t/cases into a real test.
* Small HTML::Parser documentation patch by Michael.
* Renamed attrspec 'origtext' to 'text' and 'decoded_text' to 'dtext'
* Split up Parser.xs. Moved stuff into hparser.c and util.c
* Dropped html_ prefix from internal parser functions.
* Renamed internal function html_handle() as report_event().
2.99_17 1999-12-02
* HTML::Parser documentation patch from Michael.
* Fix memory leaks in html_handler()
* Patch that makes an array legal as handler destination.
Also from Michael.
* The end of marked sections does not eat successive newline
any more.
* The artificial end event for empty tag in xml_mode did not
report an empty origtext.
* New constructor option: 'api_version'
2.99_16 1999-12-01
* Support "event" in argspec. It expands to the name of the
handler (minus "default").
* Fix core dump for large start tags. The tokens_grow() routine
needed an adjustment. Added test for this; t/largstags.t.
2.99_15 1999-11-30
* Major restructuring/simplification of callback interface based on
initial work by Michael. The main news is that you now need to
tell what arguments you want to be provided to your callbacks.
* The following parser options has been eliminated:
$p->decode_text_entities
$p->keep_case
$p->v2_compat
$p->pass_self
$p->attr_pos
2.99_14 1999-11-26
* Documentation update by Michael A. Chase.
* Fix for declaration parsing by Michael A. Chase.
* Workaround for perl5.004_05 bug. Can't return &PL_sv_undef.
2.99_13 1999-11-22
* New Parser.pm POD based on initial work by Michael A. Chase.
All new features should now be described.
* $p->callback(start => undef) will not reset the callback.
* $p->xml_mode() did not parse attributes correct because
HCTYPE_NOT_SPACE_EQ_SLASH_GT flag was never set.
* A few more tests.
2.99_12 1999-11-18
* Implemented $p->attr_pos attribute. This causes attr positions
within $origtext of the start tag to be reported instead of the
attribute values. The positions are reported as 4 numbers; end of
previous attr, start of this attr, start of attr value, and end of
attr. This should make substr() manipulations of $origtext easy.
* Implemented $p->unbroken_text attribute. This makes sure that
text segments are never broken and given back as separate text
callbacks. It delays text callbacks until some other markup
has been recognized.
* More English corrections by Michael A. Chase.
* HTML::LinkExtor now recognizes even more URI attributes as
suggested by Sean M. Burke <sburke@netadventure.net>
* Completed marked sections support. It is also now a compile
time decision if you want this supported or not. The only
drawback of enabling it should be a possible parsing speed
reduction. I have not measured this yet.
* The keys for callbacks initialized in the constructor are now
suffixed with "_cb".
* Renamed $p->pass_cbdata to $p->pass_self.
* Added magic number to the p_state struct.
2.99_11 1999-11-17
* Don't leak $@ modifications from HTML::Parser constructor.
* Included HTML::Parser POD.
* Marked sections almost work. CDATA and RCDATA should work.
* For tags that take us into literal_mode; <script>, <style>,
<xmp>, we did not recognize the end tag unless it was written
in all lower case.
2.99_10 1999-11-16
* The mkhctype and mkpfunc scripts were using \z inside RE. This
did not work for perl5.004. Replaced them with plain old
dollar signs.
2.99_09 1999-11-15
* Grammar fixes by Michael A. Chase <mchase@ix.netcom.com>
* Some more test suite patches for Win32 by Michael A. Chase
<mchase@ix.netcom.com>
* Implemented $p->strict_names attribute. By default we now
allow almost anything in tag and attribute names. This is much
closer to the behaviour of some popular browsers. This allows us
to parse broken tags like this example from the LWP mailing list:
<IMG ALIGN=MIDDLE SRC=newprevlstGr.gif ALT=[PREV LIST] BORDER=0>
* Introduced some tables in "hctype.h" and "pfunc.h". These
are built by the corresponding "mk..." script.
2.99_08 1999-11-10
* Make Parser.xs compile on perl5.004_05 too.
* New callback called 'default'. This will be called for any
document text no other callback shows an interest in.
* Patch by Michael A. Chase <mchase@ix.netcom.com> that should
help clean up files for the test suite on Win32.
* Can now set up various attributes with key/value pairs passed to
the constructor.
* $p->parse_file() will open the file in binmode()
* Pass complete processing instruction tag as second argument
to process callback.
* New boolean attribute v2_compat. This influences how attributes
are reported for start tags.
* HTML::Filter now filters process instructions too.
* Faster HTML::LinkExtor by taking advantage of the new
callback interface. The module now also uses URI.pm (instead
of the old URI::URL) to absolutize URIs.
* Faster HTML::TokeParser by taking advantage of new
accum interface.
2.99_07 1999-11-09
* Entities in attribute values are now always expanded.
* If you set the $p->decode_text_entities to a true value, then
you don't have to decode the text yourself.
* In xml_mode we don't report empty element tags as a start tag
with an extra parameter any more. Instead we generate an artificial
end tag.
* 'xml_mode' now implies 'keep_case'.
* The parser now keeps its own copy of the bool_attr_value value.
* Avoid memory leak for text callbacks
* Avoid using ERROR as a goto label.
* Introduced common internal accessor function for all boolean parser
attributes.
* Tweaks to make Parser.xs compile under perl5.004.
2.99_06 1999-11-08
* Internal fast decode_entities(). By using it we are able to make
the HTML::Entities::decode function 6 times faster than the old one
implemented in pure Perl.
* $p->bool_attr_value() can be set to influence the value that
boolean attributes will be assigned. The default is to assign
a value identical to the attribute name.
* Process instructions are reported as "PI" in @accum
* $p->xml_mode(1) modifies how processing instructions are terminated
and allows "/>" at the end of start tags.
* Turn off optimizations when compiling with gcc on Solaris. Avoids
what we believe to be a compiler bug. Should probably figure out
which versions of gcc have this bug.
2.99_05 1999-11-05
* The previous release did not even compile. I forgot to try 'make test'
before uploading.
2.99_04 1999-11-05
* Generalized <XMP>-support to cover all literal parsing. Currently
activated for <script>, <style>, <xmp> and <plaintext>.
2.99_03 1999-11-05
* <XMP>-support.
* Allow ":" in tag and attribute names
* Include rest of the HTML::* files from the old HTML::Parser
package. This should make testing easier.
2.99_02 1999-11-04
* Implemented keep_case() option. If this attribute is true, then
we don't lowercase tag and attribute names.
* Implemented accum() that takes an array reference. Tokens are
pushed onto this array instead of sent to callbacks.
* Implemented strict_comment().
2.99_01 1999-11-03
* Baseline of XS implementation
2.25 1999-11-05
* Allow ":" in attribute names as a workaround for Microsoft Excel
2000 which generates such files.
* Make deprecate warning if netscape_buggy_comment() method is
used. The method is used in strict_comment().
* Avoid duplication of parse_file() method in HTML::HeadParser.
2.24 1999-10-29
* $p->parse_file() will not close a handle passed to it any more.
If passed a filename that can't be opened it will return undef
instead of raising an exception, and strings like "*STDIN" are not
treated as globs any more.
* HTML::LinkExtor knows about background attribute of <tables>.
Patch by Clinton Wong <clintdw@netcom.com>
* HTML::TokeParser will parse large inline strings much faster now.
The string holding the document must not be changed during parsing.
2.23 1999-06-09
* Documentation updates.
2.22 1998-12-18
* Protect HTML::HeadParser from evil $SIG{__DIE__} hooks.
2.21 1998-11-13
* HTML::TokeParser can now parse strings directly and does the
right thing if you pass it a GLOB. Based on patch by
Sami Itkonen <si@iki.fi>.
* HTML::Parser now allows space before and after "--" in Netscape
comments. Patch by Peter Orbaek <poe@daimi.au.dk>.
2.20 1998-07-08
* Added HTML::TokeParser. Check it out!
2.19 1998-07-07
* Don't end a text chunk with space when we try to avoid breaking up
words.
2.18 1998-06-22
* HTML::HeadParser->parse_file will now stop parsing when the
<body> starts as it should.
* HTML::LinkExtor more easily subclassable by introducing the
$self->_found_link method.
2.17 1998-04-28
* Never split words (a sequence of non-space) between two invocations
of $self->text. This is just a simplification of the code that tried
not to break entities.
* HTML::Parser->parse_file now use smaller chunks as already
suggested by the HTML::Parser documentation.
2.16 1998-04-02
* The HTML::Parser could some times break hex entities (like )
in the middle.
* Removed remaining forced dependencies on libwww-perl modules. It
means that all tests should now pass, even if libwww-perl was not
installed previously.
* More tests.
2.14 1998-04-01
* HTML::* modules unbundled from libwww-perl-5.22

This software is Copyright (c) 1996 by Gisle Aas <gaas@cpan.org> and Michael A. Chase <mchase@ix.netcom.com>.
This is free software, licensed under:
The GNU General Public License, Version 1, February 1989
GNU GENERAL PUBLIC LICENSE
Version 1, February 1989
Copyright (C) 1989 Free Software Foundation, Inc.
51 Franklin St, 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.
Preamble
The license agreements of most software companies try to keep users
at the mercy of those companies. By contrast, our General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. The
General Public License applies to the Free Software Foundation's
software and to any other program whose authors commit to using it.
You can use it for your programs, too.
When we speak of free software, we are referring to freedom, not
price. Specifically, the General Public License is designed to make
sure that you have the freedom to give away or sell copies of free
software, that you receive source code or can get it if you want it,
that you can change the software or use pieces of it in new free
programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of a such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must tell them their rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any program or other work which
contains a notice placed by the copyright holder saying it may be
distributed under the terms of this General Public License. The
"Program", below, refers to any such program or work, and a "work based
on the Program" means either the Program or any work containing the
Program or a portion of it, either verbatim or with modifications. Each
licensee is addressed as "you".
1. You may copy and distribute verbatim copies of the Program's 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
General Public License and to the absence of any warranty; and give any
other recipients of the Program a copy of this General Public License
along with the Program. You may charge a fee for the physical act of
transferring a copy.
2. You may modify your copy or copies of the Program or any portion of
it, and copy and distribute such modifications under the terms of Paragraph
1 above, provided that you also do the following:
a) cause the modified files to carry prominent notices stating that
you changed the files and the date of any change; and
b) cause the whole of any work that you distribute or publish, that
in whole or in part contains the Program or any part thereof, either
with or without modifications, to be licensed at no charge to all
third parties under the terms of this General Public License (except
that you may choose to grant warranty protection to some or all
third parties, at your option).
c) If the modified program normally reads commands interactively when
run, you must cause it, when started running for such interactive use
in the simplest and most usual way, to print or display an
announcement including an appropriate copyright notice and a notice
that there is no warranty (or else, saying that you provide a
warranty) and that users may redistribute the program under these
conditions, and telling the user how to view a copy of this General
Public License.
d) 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.
Mere aggregation of another independent work with the Program (or its
derivative) on a volume of a storage or distribution medium does not bring
the other work under the scope of these terms.
3. You may copy and distribute the Program (or a portion or derivative of
it, under Paragraph 2) in object code or executable form under the terms of
Paragraphs 1 and 2 above provided that you also do one of the following:
a) accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of
Paragraphs 1 and 2 above; or,
b) accompany it with a written offer, valid for at least three
years, to give any third party free (except for a nominal charge
for the cost of distribution) a complete machine-readable copy of the
corresponding source code, to be distributed under the terms of
Paragraphs 1 and 2 above; or,
c) accompany it with the information you received as to where the
corresponding source code may be obtained. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form alone.)
Source code for a work means the preferred form of the work for making
modifications to it. For an executable file, complete source code means
all the source code for all modules it contains; but, as a special
exception, it need not include source code for modules which are standard
libraries that accompany the operating system on which the executable
file runs, or for standard header files or definitions files that
accompany that operating system.
4. You may not copy, modify, sublicense, distribute or transfer the
Program except as expressly provided under this General Public License.
Any attempt otherwise to copy, modify, sublicense, distribute or transfer
the Program is void, and will automatically terminate your rights to use
the Program under this License. However, parties who have received
copies, or rights to use copies, from you under this General Public
License will not have their licenses terminated so long as such parties
remain in full compliance.
5. By copying, distributing or modifying the Program (or any work based
on the Program) you indicate your acceptance of this license to do so,
and all its terms and conditions.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the original
licensor to copy, distribute or modify the Program subject to these
terms and conditions. You may not impose any further restrictions on the
recipients' exercise of the rights granted herein.
7. The Free Software Foundation may publish revised and/or new versions
of the 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 Program
specifies a version number of the 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 Program does not specify a version number of
the license, you may choose any version ever published by the Free Software
Foundation.
8. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, 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
9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "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 PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
10. 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 PROGRAM 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 PROGRAM (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 PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to humanity, the best way to achieve this is to make it
free software which everyone can redistribute and change under these
terms.
To do so, attach the following notices to the program. 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.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 1, or (at your option)
any later version.
This program 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 General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; 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.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19xx name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the
appropriate parts of the General Public License. Of course, the
commands you use may be called something other than `show w' and `show
c'; they could even be mouse-clicks or menu items--whatever suits your
program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the
program `Gnomovision' (a program to direct compilers to make passes
at assemblers) written by James Hacker.

The Artistic License 1.0
The Artistic License
Preamble
The intent of this document is to state the conditions under which a Package
may be copied, such that the Copyright Holder maintains some semblance of
artistic control over the development of the package, while giving the users of
the package the right to use and distribute the Package in a more-or-less
customary fashion, plus the right to make reasonable modifications.
Definitions:
- "Package" refers to the collection of files distributed by the Copyright
Holder, and derivatives of that collection of files created through
textual modification.
- "Standard Version" refers to such a Package if it has not been modified,
or has been modified in accordance with the wishes of the Copyright
Holder.
- "Copyright Holder" is whoever is named in the copyright or copyrights for
the package.
- "You" is you, if you're thinking about copying or distributing this Package.
- "Reasonable copying fee" is whatever you can justify on the basis of media
cost, duplication charges, time of people involved, and so on. (You will
not be required to justify it to the Copyright Holder, but only to the
computing community at large as a market that must bear the fee.)
- "Freely Available" means that no fee is charged for the item itself, though
there may be fees involved in handling the item. It also means that
recipients of the item may redistribute it under the same conditions they
received it.
1. You may make and give away verbatim copies of the source form of the
Standard Version of this Package without restriction, provided that you
duplicate all of the original copyright notices and associated disclaimers.
2. You may apply bug fixes, portability fixes and other modifications derived
from the Public Domain or from the Copyright Holder. A Package modified in such
a way shall still be considered the Standard Version.
3. You may otherwise modify your copy of this Package in any way, provided that
you insert a prominent notice in each changed file stating how and when you
changed that file, and provided that you do at least ONE of the following:
a) place your modifications in the Public Domain or otherwise make them
Freely Available, such as by posting said modifications to Usenet or an
equivalent medium, or placing the modifications on a major archive site
such as ftp.uu.net, or by allowing the Copyright Holder to include your
modifications in the Standard Version of the Package.
b) use the modified Package only within your corporation or organization.
c) rename any non-standard executables so the names do not conflict with
standard executables, which must also be provided, and provide a separate
manual page for each non-standard executable that clearly documents how it
differs from the Standard Version.
d) make other distribution arrangements with the Copyright Holder.
4. You may distribute the programs of this Package in object code or executable
form, provided that you do at least ONE of the following:
a) distribute a Standard Version of the executables and library files,
together with instructions (in the manual page or equivalent) on where to
get the Standard Version.
b) accompany the distribution with the machine-readable source of the Package
with your modifications.
c) accompany any non-standard executables with their corresponding Standard
Version executables, giving the non-standard executables non-standard
names, and clearly documenting the differences in manual pages (or
equivalent), together with instructions on where to get the Standard
Version.
d) make other distribution arrangements with the Copyright Holder.
5. You may charge a reasonable copying fee for any distribution of this
Package. You may charge any fee you choose for support of this Package. You
may not charge a fee for this Package itself. However, you may distribute this
Package in aggregate with other (possibly commercial) programs as part of a
larger (possibly commercial) software distribution provided that you do not
advertise this Package as a product of your own.
6. The scripts and library files supplied as input to or produced as output
from the programs of this Package do not automatically fall under the copyright
of this Package, but belong to whomever generated them, and may be sold
commercially, and may be aggregated with this Package.
7. C or perl subroutines supplied by you and linked into this Package shall not
be considered part of this Package.
8. The name of the Copyright Holder may not be used to endorse or promote
products derived from this software without specific prior written permission.
9. THIS PACKAGE IS PROVIDED "AS IS" AND WITHOUT ANY EXPRESS OR IMPLIED
WARRANTIES, INCLUDING, WITHOUT LIMITATION, THE IMPLIED WARRANTIES OF
MERCHANTIBILITY AND FITNESS FOR A PARTICULAR PURPOSE.

entities that map to characters in the 0 .. 255 range. The term
"Unicode entities" means named entities that are not "Latin-1
entities".

=head1 NAME
HTML::LinkExtor - Extract links from an HTML document
=head1 SYNOPSIS
require HTML::LinkExtor;
$p = HTML::LinkExtor->new(\&cb, "http://www.perl.org/");
sub cb {
my($tag, %links) = @_;
print "$tag @{[%links]}\n";
}
$p->parse_file("index.html");
=head1 DESCRIPTION
I<HTML::LinkExtor> is an HTML parser that extracts links from an
HTML document. The I<HTML::LinkExtor> is a subclass of
I<HTML::Parser>. This means that the document should be given to the
parser by calling the $p->parse() or $p->parse_file() methods.
=cut
use strict;
use HTML::Tagset ();
# legacy (some applications grabs this hash directly)
our %LINK_ELEMENT;
*LINK_ELEMENT = \%HTML::Tagset::linkElements;
=over 4
=item $p = HTML::LinkExtor->new
=item $p = HTML::LinkExtor->new( $callback )
=item $p = HTML::LinkExtor->new( $callback, $base )
The constructor takes two optional arguments. The first is a reference
to a callback routine. It will be called as links are found. If a
callback is not provided, then links are just accumulated internally
and can be retrieved by calling the $p->links() method.
The $base argument is an optional base URL used to absolutize all URLs found.
You need to have the I<URI> module installed if you provide $base.
The callback is called with the lowercase tag name as first argument,
and then all link attributes as separate key/value pairs. All
non-link attributes are removed.

my $cb = $self->{extractlink_cb};
if ($cb) {
&$cb(@_);
} else {
push(@{$self->{'links'}}, [@_]);
}
}
=item $p->links
Returns a list of all links found in the document. The returned
values will be anonymous arrays with the following elements:
[$tag, $attr => $url1, $attr2 => $url2,...]
The $p->links method will also truncate the internal link list. This
means that if the method is called twice without any parsing
between them the second call will return an empty list.
Also note that $p->links will always be empty if a callback routine
was provided when the I<HTML::LinkExtor> was created.
=cut
sub links
{
my $self = shift;
exists($self->{'links'}) ? @{delete $self->{'links'}} : ();
}
# We override the parse_file() method so that we can clear the links
# before we start a new file.
sub parse_file
{
my $self = shift;
delete $self->{'links'};
$self->SUPER::parse_file(@_);
}
=back
=head1 EXAMPLE
This is an example showing how you can extract links from a document
received using LWP:
use LWP::UserAgent;
use HTML::LinkExtor;
use URI::URL;
$url = "http://www.perl.org/"; # for instance
$ua = LWP::UserAgent->new;
# Set up a callback that collect image links
my @imgs = ();
sub callback {
my($tag, %attr) = @_;
return if $tag ne 'img'; # we only look closer at <img ...>
push(@imgs, values %attr);
}
# Make the parser. Unfortunately, we don't know the base yet
# (it might be different from $url)
$p = HTML::LinkExtor->new(\&callback);
# Request document and parse it as it arrives
$res = $ua->request(HTTP::Request->new(GET => $url),
sub {$p->parse($_[0])});
# Expand all image URLs to absolute ones
my $base = $res->base;
@imgs = map { $_ = url($_, $base)->abs; } @imgs;
# Print them out
print join("\n", @imgs), "\n";

=head1 NAME
HTML::Entities - Encode or decode strings with HTML entities
=head1 SYNOPSIS
use HTML::Entities;
$a = "Våre norske tegn bør æres";
decode_entities($a);
encode_entities($a, "\200-\377");
For example, this:
$input = "vis-à-vis Beyoncé's naïve\npapier-mâché résumé";
print encode_entities($input), "\n"
Prints this out:
vis-à-vis Beyoncé's naïve
papier-mâché résumé
=head1 DESCRIPTION
This module deals with encoding and decoding of strings with HTML
character entities. The module provides the following functions:
=over 4
=item decode_entities( $string, ... )
This routine replaces HTML entities found in the $string with the
corresponding Unicode character. Unrecognized entities are left alone.
If multiple strings are provided as argument they are each decoded
separately and the same number of strings are returned.
If called in void context the arguments are decoded in-place.
This routine is exported by default.
=item _decode_entities( $string, \%entity2char )
=item _decode_entities( $string, \%entity2char, $expand_prefix )
This will in-place replace HTML entities in $string. The %entity2char
hash must be provided. Named entities not found in the %entity2char
hash are left alone. Numeric entities are expanded unless their value
overflow.
The keys in %entity2char are the entity names to be expanded and their
values are what they should expand into. The values do not have to be
single character strings. If a key has ";" as suffix,
then occurrences in $string are only expanded if properly terminated
with ";". Entities without ";" will be expanded regardless of how
they are terminated for compatibility with how common browsers treat
entities in the Latin-1 range.
If $expand_prefix is TRUE then entities without trailing ";" in
%entity2char will even be expanded as a prefix of a longer
unrecognized name. The longest matching name in %entity2char will be
used. This is mainly present for compatibility with an MSIE
misfeature.
$string = "foo bar";
_decode_entities($string, { nb => "@", nbsp => "\xA0" }, 1);
print $string; # will print "foo bar"
This routine is exported by default.
=item encode_entities( $string )
=item encode_entities( $string, $unsafe_chars )
This routine replaces unsafe characters in $string with their entity
representation. A second argument can be given to specify which characters to
consider unsafe. The unsafe characters is specified using the regular
expression character class syntax (what you find within brackets in regular
expressions).
The default set of characters to encode are control chars, high-bit chars, and
the C<< < >>, C<< & >>, C<< > >>, C<< ' >> and C<< " >> characters. But this,
for example, would encode I<just> the C<< < >>, C<< & >>, C<< > >>, and C<< "
>> characters:
$encoded = encode_entities($input, '<>&"');
and this would only encode non-plain ASCII:
$encoded = encode_entities($input, '^\n\x20-\x25\x27-\x7e');
This routine is exported by default.
=item encode_entities_numeric( $string )
=item encode_entities_numeric( $string, $unsafe_chars )
This routine works just like encode_entities, except that the replacement
entities are always C<&#xI<hexnum>;> and never C<&I<entname>;>. For
example, C<encode_entities("r\xF4le")> returns "rôle", but
C<encode_entities_numeric("r\xF4le")> returns "rôle".
This routine is I<not> exported by default. But you can always
export it with C<use HTML::Entities qw(encode_entities_numeric);>
or even C<use HTML::Entities qw(:DEFAULT encode_entities_numeric);>
=back
All these routines modify the string passed as the first argument, if
called in a void context. In scalar and array contexts, the encoded or
decoded string is returned (without changing the input string).
If you prefer not to import these routines into your namespace, you can
call them as:
use HTML::Entities ();
$decoded = HTML::Entities::decode($a);
$encoded = HTML::Entities::encode($a);
$encoded = HTML::Entities::encode_numeric($a);
The module can also export the %char2entity and the %entity2char
hashes, which contain the mapping from all characters to the
corresponding entities (and vice versa, respectively).

=head1 NAME
HTML::Filter - Filter HTML text through the parser
=head1 NOTE
B<This module is deprecated.> The C<HTML::Parser> now provides the
functionally of C<HTML::Filter> much more efficiently with the
C<default> handler.
=head1 SYNOPSIS
require HTML::Filter;
$p = HTML::Filter->new->parse_file("index.html");
=head1 DESCRIPTION
C<HTML::Filter> is an HTML parser that by default prints the
original text of each HTML element (a slow version of cat(1) basically).
The callback methods may be overridden to modify the filtering for some
HTML elements and you can override output() method which is called to
print the HTML text.
C<HTML::Filter> is a subclass of C<HTML::Parser>. This means that
the document should be given to the parser by calling the $p->parse()
or $p->parse_file() methods.

The first example is a filter that will remove all comments from an
HTML file. This is achieved by simply overriding the comment method
to do nothing.
package CommentStripper;
require HTML::Filter;
@ISA=qw(HTML::Filter);
sub comment { } # ignore comments
The second example shows a filter that will remove any E<lt>TABLE>s
found in the HTML file. We specialize the start() and end() methods
to count table tags and then make output not happen when inside a
table.
package TableStripper;
require HTML::Filter;
@ISA=qw(HTML::Filter);
sub start
{
my $self = shift;
$self->{table_seen}++ if $_[0] eq "table";
$self->SUPER::start(@_);
}
sub end
{
my $self = shift;
$self->SUPER::end(@_);
$self->{table_seen}-- if $_[0] eq "table";
}
sub output
{
my $self = shift;
unless ($self->{table_seen}) {
$self->SUPER::output(@_);
}
}
If you want to collect the parsed text internally you might want to do
something like this:
package FilterIntoString;
require HTML::Filter;
@ISA=qw(HTML::Filter);
sub output { push(@{$_[0]->{fhtml}}, $_[1]) }
sub filtered_html { join("", @{$_[0]->{fhtml}}) }

=head1 DESCRIPTION
Objects of the C<HTML::Parser> class will recognize markup and
separate it from plain text (alias data content) in HTML
documents. As different kinds of markup and text are recognized, the
corresponding event handlers are invoked.
C<HTML::Parser> is not a generic SGML parser. We have tried to
make it able to deal with the HTML that is actually "out there", and
it normally parses as closely as possible to the way the popular web
browsers do it instead of strictly following one of the many HTML
specifications from W3C. Where there is disagreement, there is often
an option that you can enable to get the official behaviour.
The document to be parsed may be supplied in arbitrary chunks. This
makes on-the-fly parsing as documents are received from the network
possible.
If event driven parsing does not feel right for your application, you
might want to use C<HTML::PullParser>. This is an C<HTML::Parser>
subclass that allows a more conventional program structure.
=head1 METHODS
The following method is used to construct a new C<HTML::Parser> object:
=over
=item $p = HTML::Parser->new( %options_and_handlers )
This class method creates a new C<HTML::Parser> object and
returns it. Key/value argument pairs may be provided to assign event
handlers or initialize parser options. The handlers and parser
options can also be set or modified later by the method calls described below.
If a top level key is in the form "<event>_h" (e.g., "text_h") then it
assigns a handler to that event, otherwise it initializes a parser
option. The event handler specification value must be an array
reference. Multiple handlers may also be assigned with the 'handlers
=> [%handlers]' option. See examples below.
If new() is called without any arguments, it will create a parser that
uses callback methods compatible with version 2 of C<HTML::Parser>.
See the section on "version 2 compatibility" below for details.
The special constructor option 'api_version => 2' can be used to
initialize version 2 callbacks while still setting other options and
handlers. The 'api_version => 3' option can be used if you don't want
to set any options and don't want to fall back to v2 compatible
mode.
Examples:
$p = HTML::Parser->new(
api_version => 3,
text_h => [ sub {...}, "dtext" ]
);
This creates a new parser object with a text event handler subroutine
that receives the original text with general entities decoded.
$p = HTML::Parser->new(
api_version => 3,
start_h => [ 'my_start', "self,tokens" ]
);
This creates a new parser object with a start event handler method
that receives the $p and the tokens array.
$p = HTML::Parser->new(
api_version => 3,
handlers => {
text => [\@array, "event,text"],
comment => [\@array, "event,text"],
}
);
This creates a new parser object that stores the event type and the
original text in @array for text and comment events.
=back
The following methods feed the HTML document
to the C<HTML::Parser> object:
=over
=item $p->parse( $string )
Parse $string as the next chunk of the HTML document. Handlers invoked should
not attempt to modify the $string in-place until $p->parse returns.
If an invoked event handler aborts parsing by calling $p->eof, then $p->parse()
will return a FALSE value. Otherwise the return value is a reference to the
parser object ($p).
=item $p->parse( $code_ref )
If a code reference is passed as the argument to be parsed, then the
chunks to be parsed are obtained by invoking this function repeatedly.
Parsing continues until the function returns an empty (or undefined)
result. When this happens $p->eof is automatically signaled.
Parsing will also abort if one of the event handlers calls $p->eof.
The effect of this is the same as:
while (1) {
my $chunk = &$code_ref();
if (!defined($chunk) || !length($chunk)) {
$p->eof;
return $p;
}
$p->parse($chunk) || return undef;
}
But it is more efficient as this loop runs internally in XS code.
=item $p->parse_file( $file )
Parse text directly from a file. The $file argument can be a
filename, an open file handle, or a reference to an open file
handle.
If $file contains a filename and the file can't be opened, then the
method returns an undefined value and $! tells why it failed.
Otherwise the return value is a reference to the parser object.
If a file handle is passed as the $file argument, then the file will
normally be read until EOF, but not closed.
If an invoked event handler aborts parsing by calling $p->eof,
then $p->parse_file() may not have read the entire file.
On systems with multi-byte line terminators, the values passed for the
offset and length argspecs may be too low if parse_file() is called on
a file handle that is not in binary mode.
If a filename is passed in, then parse_file() will open the file in
binary mode.
=item $p->eof
Signals the end of the HTML document. Calling the $p->eof method
outside a handler callback will flush any remaining buffered text
(which triggers the C<text> event if there is any remaining text).
Calling $p->eof inside a handler will terminate parsing at that point
and cause $p->parse to return a FALSE value. This also terminates
parsing by $p->parse_file().
After $p->eof has been called, the parse() and parse_file() methods
can be invoked to feed new documents with the parser object.
The return value from eof() is a reference to the parser object.
=back
Most parser options are controlled by boolean attributes.
Each boolean attribute is enabled by calling the corresponding method
with a TRUE argument and disabled with a FALSE argument. The
attribute value is left unchanged if no argument is given. The return
value from each method is the old attribute value.
Methods that can be used to get and/or set parser options are:
=over
=item $p->attr_encoded
=item $p->attr_encoded( $bool )
By default, the C<attr> and C<@attr> argspecs will have general
entities for attribute values decoded. Enabling this attribute leaves
entities alone.
=item $p->backquote
=item $p->backquote( $bool )
By default, only ' and " are recognized as quote characters around
attribute values. MSIE also recognizes backquotes for some reason.
Enabling this attribute provides compatibility with this behaviour.
=item $p->boolean_attribute_value( $val )
This method sets the value reported for boolean attributes inside HTML
start tags. By default, the name of the attribute is also used as its
value. This affects the values reported for C<tokens> and C<attr>
argspecs.
=item $p->case_sensitive
=item $p->case_sensitive( $bool )
By default, tag names and attribute names are down-cased. Enabling this
attribute leaves them as found in the HTML source document.
=item $p->closing_plaintext
=item $p->closing_plaintext( $bool )
By default, C<plaintext> element can never be closed. Everything up to
the end of the document is parsed in CDATA mode. This historical
behaviour is what at least MSIE does. Enabling this attribute makes
closing C< </plaintext> > tag effective and the parsing process will resume
after seeing this tag. This emulates early gecko-based browsers.
=item $p->empty_element_tags
=item $p->empty_element_tags( $bool )
By default, empty element tags are not recognized as such and the "/"
before ">" is just treated like a normal name character (unless
C<strict_names> is enabled). Enabling this attribute make
C<HTML::Parser> recognize these tags.
Empty element tags look like start tags, but end with the character
sequence "/>" instead of ">". When recognized by C<HTML::Parser> they
cause an artificial end event in addition to the start event. The
C<text> for the artificial end event will be empty and the C<tokenpos>
array will be undefined even though the token array will have one
element containing the tag name.
=item $p->marked_sections
=item $p->marked_sections( $bool )
By default, section markings like <![CDATA[...]]]]><![CDATA[> are treated like
ordinary text. When this attribute is enabled section markings are
honoured.
There are currently no events associated with the marked section
markup, but the text can be returned as C<skipped_text>.
=item $p->strict_comment
=item $p->strict_comment( $bool )
By default, comments are terminated by the first occurrence of "-->".
This is the behaviour of most popular browsers (like Mozilla, Opera and
MSIE), but it is not correct according to the official HTML
standard. Officially, you need an even number of "--" tokens before
the closing ">" is recognized and there may not be anything but
whitespace between an even and an odd "--".
The official behaviour is enabled by enabling this attribute.
Enabling of 'strict_comment' also disables recognizing these forms as
comments:
</ comment>
<! comment>
=item $p->strict_end
=item $p->strict_end( $bool )
By default, attributes and other junk are allowed to be present on end tags in a
manner that emulates MSIE's behaviour.
The official behaviour is enabled with this attribute. If enabled,
only whitespace is allowed between the tagname and the final ">".
=item $p->strict_names
=item $p->strict_names( $bool )
By default, almost anything is allowed in tag and attribute names.
This is the behaviour of most popular browsers and allows us to parse
some broken tags with invalid attribute values like:
<IMG SRC=newprevlstGr.gif ALT=[PREV LIST] BORDER=0>
By default, "LIST]" is parsed as a boolean attribute, not as
part of the ALT value as was clearly intended. This is also what
Mozilla sees.
The official behaviour is enabled by enabling this attribute. If
enabled, it will cause the tag above to be reported as text
since "LIST]" is not a legal attribute name.
=item $p->unbroken_text
=item $p->unbroken_text( $bool )
By default, blocks of text are given to the text handler as soon as
possible (but the parser takes care always to break text at a
boundary between whitespace and non-whitespace so single words and
entities can always be decoded safely). This might create breaks that
make it hard to do transformations on the text. When this attribute is
enabled, blocks of text are always reported in one piece. This will
delay the text event until the following (non-text) event has been
recognized by the parser.
Note that the C<offset> argspec will give you the offset of the first
segment of text and C<length> is the combined length of the segments.
Since there might be ignored tags in between, these numbers can't be
used to directly index in the original document file.
=item $p->utf8_mode
=item $p->utf8_mode( $bool )
Enable this option when parsing raw undecoded UTF-8. This tells the
parser that the entities expanded for strings reported by C<attr>,
C<@attr> and C<dtext> should be expanded as decoded UTF-8 so they end
up compatible with the surrounding text.
If C<utf8_mode> is enabled then it is an error to pass strings
containing characters with code above 255 to the parse() method, and
the parse() method will croak if you try.
Example: The Unicode character "\x{2665}" is "\xE2\x99\xA5" when UTF-8
encoded. The character can also be represented by the entity
"♥" or "♥". If we feed the parser:
$p->parse("\xE2\x99\xA5♥");
then C<dtext> will be reported as "\xE2\x99\xA5\x{2665}" without
C<utf8_mode> enabled, but as "\xE2\x99\xA5\xE2\x99\xA5" when enabled.
The later string is what you want.
This option is only available with perl-5.8 or better.
=item $p->xml_mode
=item $p->xml_mode( $bool )
Enabling this attribute changes the parser to allow some XML
constructs. This enables the behaviour controlled by individually by
the C<case_sensitive>, C<empty_element_tags>, C<strict_names> and
C<xml_pic> attributes and also suppresses special treatment of
elements that are parsed as CDATA for HTML.
=item $p->xml_pic
=item $p->xml_pic( $bool )
By default, I<processing instructions> are terminated by ">". When
this attribute is enabled, processing instructions are terminated by
"?>" instead.
=back
As markup and text is recognized, handlers are invoked. The following
method is used to set up handlers for different events:
=over
=item $p->handler( event => \&subroutine, $argspec )
=item $p->handler( event => $method_name, $argspec )
=item $p->handler( event => \@accum, $argspec )
=item $p->handler( event => "" );
=item $p->handler( event => undef );
=item $p->handler( event );
This method assigns a subroutine, method, or array to handle an event.
Event is one of C<text>, C<start>, C<end>, C<declaration>, C<comment>,
C<process>, C<start_document>, C<end_document> or C<default>.
The C<\&subroutine> is a reference to a subroutine which is called to handle
the event.
The C<$method_name> is the name of a method of $p which is called to handle
the event.
The C<@accum> is an array that will hold the event information as
sub-arrays.
If the second argument is "", the event is ignored.
If it is undef, the default handler is invoked for the event.
The C<$argspec> is a string that describes the information to be reported
for the event. Any requested information that does not apply to a
specific event is passed as C<undef>. If argspec is omitted, then it
is left unchanged.
The return value from $p->handler is the old callback routine or a
reference to the accumulator array.
Any return values from handler callback routines/methods are always
ignored. A handler callback can request parsing to be aborted by
invoking the $p->eof method. A handler callback is not allowed to
invoke the $p->parse() or $p->parse_file() method. An exception will
be raised if it tries.
Examples:
$p->handler(start => "start", 'self, attr, attrseq, text' );
This causes the "start" method of object C<$p> to be called for 'start' events.
The callback signature is C<< $p->start(\%attr, \@attr_seq, $text) >>.
$p->handler(start => \&start, 'attr, attrseq, text' );
This causes subroutine start() to be called for 'start' events.
The callback signature is start(\%attr, \@attr_seq, $text).
$p->handler(start => \@accum, '"S", attr, attrseq, text' );
This causes 'start' event information to be saved in @accum.
The array elements will be ['S', \%attr, \@attr_seq, $text].
$p->handler(start => "");
This causes 'start' events to be ignored. It also suppresses
invocations of any default handler for start events. It is in most
cases equivalent to $p->handler(start => sub {}), but is more
efficient. It is different from the empty-sub-handler in that
C<skipped_text> is not reset by it.
$p->handler(start => undef);
This causes no handler to be associated with start events.
If there is a default handler it will be invoked.
=back
Filters based on tags can be set up to limit the number of events
reported. The main bottleneck during parsing is often the huge number
of callbacks made from the parser. Applying filters can improve
performance significantly.
The following methods control filters:
=over
=item $p->ignore_elements( @tags )
Both the C<start> event and the C<end> event as well as any events that
would be reported in between are suppressed. The ignored elements can
contain nested occurrences of itself. Example:
$p->ignore_elements(qw(script style));
The C<script> and C<style> tags will always nest properly since their
content is parsed in CDATA mode. For most other tags
C<ignore_elements> must be used with caution since HTML is often not
I<well formed>.
=item $p->ignore_tags( @tags )
Any C<start> and C<end> events involving any of the tags given are
suppressed. To reset the filter (i.e. don't suppress any C<start> and
C<end> events), call C<ignore_tags> without an argument.
=item $p->report_tags( @tags )
Any C<start> and C<end> events involving any of the tags I<not> given
are suppressed. To reset the filter (i.e. report all C<start> and
C<end> events), call C<report_tags> without an argument.
=back
Internally, the system has two filter lists, one for C<report_tags>
and one for C<ignore_tags>, and both filters are applied. This
effectively gives C<ignore_tags> precedence over C<report_tags>.
Examples:
$p->ignore_tags(qw(style));
$p->report_tags(qw(script style));
results in only C<script> events being reported.
=head2 Argspec
Argspec is a string containing a comma-separated list that describes
the information reported by the event. The following argspec
identifier names can be used:
=over
=item C<attr>
Attr causes a reference to a hash of attribute name/value pairs to be
passed.
Boolean attributes' values are either the value set by
$p->boolean_attribute_value, or the attribute name if no value has been
set by $p->boolean_attribute_value.
This passes undef except for C<start> events.
Unless C<xml_mode> or C<case_sensitive> is enabled, the attribute
names are forced to lower case.
General entities are decoded in the attribute values and
one layer of matching quotes enclosing the attribute values is removed.
The Unicode character set is assumed for entity decoding.
=item C<@attr>
Basically the same as C<attr>, but keys and values are passed as
individual arguments and the original sequence of the attributes is
kept. The parameters passed will be the same as the @attr calculated
here:
@attr = map { $_ => $attr->{$_} } @$attrseq;
assuming $attr and $attrseq here are the hash and array passed as the
result of C<attr> and C<attrseq> argspecs.
This passes no values for events besides C<start>.
=item C<attrseq>
Attrseq causes a reference to an array of attribute names to be
passed. This can be useful if you want to walk the C<attr> hash in
the original sequence.
This passes undef except for C<start> events.
Unless C<xml_mode> or C<case_sensitive> is enabled, the attribute
names are forced to lower case.
=item C<column>
Column causes the column number of the start of the event to be passed.
The first column on a line is 0.
=item C<dtext>
Dtext causes the decoded text to be passed. General entities are
automatically decoded unless the event was inside a CDATA section or
was between literal start and end tags (C<script>, C<style>,
C<xmp>, C<iframe>, C<title>, C<textarea> and C<plaintext>).
The Unicode character set is assumed for entity decoding. With Perl
version 5.6 or earlier only the Latin-1 range is supported, and
entities for characters outside the range 0..255 are left unchanged.
This passes undef except for C<text> events.
=item C<event>
Event causes the event name to be passed.
The event name is one of C<text>, C<start>, C<end>, C<declaration>,
C<comment>, C<process>, C<start_document> or C<end_document>.
=item C<is_cdata>
Is_cdata causes a TRUE value to be passed if the event is inside a CDATA
section or between literal start and end tags (C<script>,
C<style>, C<xmp>, C<iframe>, C<title>, C<textarea> and C<plaintext>).
if the flag is FALSE for a text event, then you should normally
either use C<dtext> or decode the entities yourself before the text is
processed further.
=item C<length>
Length causes the number of bytes of the source text of the event to
be passed.
=item C<line>
Line causes the line number of the start of the event to be passed.
The first line in the document is 1. Line counting doesn't start
until at least one handler requests this value to be reported.
=item C<offset>
Offset causes the byte position in the HTML document of the start of
the event to be passed. The first byte in the document has offset 0.
=item C<offset_end>
Offset_end causes the byte position in the HTML document of the end of
the event to be passed. This is the same as C<offset> + C<length>.
=item C<self>
Self causes the current object to be passed to the handler. If the
handler is a method, this must be the first element in the argspec.
An alternative to passing self as an argspec is to register closures
that capture $self by themselves as handlers. Unfortunately this
creates circular references which prevent the HTML::Parser object
from being garbage collected. Using the C<self> argspec avoids this
problem.
=item C<skipped_text>
Skipped_text returns the concatenated text of all the events that have
been skipped since the last time an event was reported. Events might
be skipped because no handler is registered for them or because some
filter applies. Skipped text also includes marked section markup,
since there are no events that can catch it.
If an C<"">-handler is registered for an event, then the text for this
event is not included in C<skipped_text>. Skipped text both before
and after the C<"">-event is included in the next reported
C<skipped_text>.
=item C<tag>
Same as C<tagname>, but prefixed with "/" if it belongs to an C<end>
event and "!" for a declaration. The C<tag> does not have any prefix
for C<start> events, and is in this case identical to C<tagname>.
=item C<tagname>
This is the element name (or I<generic identifier> in SGML jargon) for
start and end tags. Since HTML is case insensitive, this name is
forced to lower case to ease string matching.
Since XML is case sensitive, the tagname case is not changed when
C<xml_mode> is enabled. The same happens if the C<case_sensitive> attribute
is set.
The declaration type of declaration elements is also passed as a tagname,
even if that is a bit strange.
In fact, in the current implementation tagname is
identical to C<token0> except that the name may be forced to lower case.
=item C<token0>
Token0 causes the original text of the first token string to be
passed. This should always be the same as $tokens->[0].
For C<declaration> events, this is the declaration type.
For C<start> and C<end> events, this is the tag name.
For C<process> and non-strict C<comment> events, this is everything
inside the tag.
This passes undef if there are no tokens in the event.
=item C<tokenpos>
Tokenpos causes a reference to an array of token positions to be
passed. For each string that appears in C<tokens>, this array
contains two numbers. The first number is the offset of the start of
the token in the original C<text> and the second number is the length
of the token.
Boolean attributes in a C<start> event will have (0,0) for the
attribute value offset and length.
This passes undef if there are no tokens in the event (e.g., C<text>)
and for artificial C<end> events triggered by empty element tags.
If you are using these offsets and lengths to modify C<text>, you
should either work from right to left, or be very careful to calculate
the changes to the offsets.
=item C<tokens>
Tokens causes a reference to an array of token strings to be passed.
The strings are exactly as they were found in the original text,
no decoding or case changes are applied.
For C<declaration> events, the array contains each word, comment, and
delimited string starting with the declaration type.
For C<comment> events, this contains each sub-comment. If
$p->strict_comments is disabled, there will be only one sub-comment.
For C<start> events, this contains the original tag name followed by
the attribute name/value pairs. The values of boolean attributes will
be either the value set by $p->boolean_attribute_value, or the
attribute name if no value has been set by
$p->boolean_attribute_value.
For C<end> events, this contains the original tag name (always one token).
For C<process> events, this contains the process instructions (always one
token).
This passes C<undef> for C<text> events.
=item C<text>
Text causes the source text (including markup element delimiters) to be
passed.
=item C<undef>
Pass an undefined value. Useful as padding where the same handler
routine is registered for multiple events.
=item C<'...'>
A literal string of 0 to 255 characters enclosed
in single (') or double (") quotes is passed as entered.
=back
The whole argspec string can be wrapped up in C<'@{...}'> to signal
that the resulting event array should be flattened. This only makes a
difference if an array reference is used as the handler target.
Consider this example:
$p->handler(text => [], 'text');
$p->handler(text => [], '@{text}']);
With two text events; C<"foo">, C<"bar">; then the first example will end
up with [["foo"], ["bar"]] and the second with ["foo", "bar"] in
the handler target array.
=head2 Events
Handlers for the following events can be registered:
=over
=item C<comment>
This event is triggered when a markup comment is recognized.
Example:
<!-- This is a comment -- -- So is this -->
=item C<declaration>
This event is triggered when a I<markup declaration> is recognized.
For typical HTML documents, the only declaration you are
likely to find is <!DOCTYPE ...>.
Example:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
DTDs inside <!DOCTYPE ...> will confuse HTML::Parser.
=item C<default>
This event is triggered for events that do not have a specific
handler. You can set up a handler for this event to catch stuff you
did not want to catch explicitly.
=item C<end>
This event is triggered when an end tag is recognized.
Example:
</A>
=item C<end_document>
This event is triggered when $p->eof is called and after any remaining
text is flushed. There is no document text associated with this event.
=item C<process>
This event is triggered when a processing instructions markup is
recognized.
The format and content of processing instructions are system and
application dependent.
Examples:
<? HTML processing instructions >
<? XML processing instructions ?>
=item C<start>
This event is triggered when a start tag is recognized.
Example:
<A HREF="http://www.perl.com/">
=item C<start_document>
This event is triggered before any other events for a new document. A
handler for it can be used to initialize stuff. There is no document
text associated with this event.
=item C<text>
This event is triggered when plain text (characters) is recognized.
The text may contain multiple lines. A sequence of text may be broken
between several text events unless $p->unbroken_text is enabled.
The parser will make sure that it does not break a word or a sequence
of whitespace between two text events.
=back
=head2 Unicode
C<HTML::Parser> can parse Unicode strings when running under
perl-5.8 or better. If Unicode is passed to $p->parse() then chunks
of Unicode will be reported to the handlers. The offset and length
argspecs will also report their position in terms of characters.
It is safe to parse raw undecoded UTF-8 if you either avoid decoding
entities and make sure to not use I<argspecs> that do, or enable the
C<utf8_mode> for the parser. Parsing of undecoded UTF-8 might be
useful when parsing from a file where you need the reported offsets
and lengths to match the byte offsets in the file.
If a filename is passed to $p->parse_file() then the file will be read
in binary mode. This will be fine if the file contains only ASCII or
Latin-1 characters. If the file contains UTF-8 encoded text then care
must be taken when decoding entities as described in the previous
paragraph, but better is to open the file with the UTF-8 layer so that
it is decoded properly:
open(my $fh, "<:utf8", "index.html") || die "...: $!";
$p->parse_file($fh);
If the file contains text encoded in a charset besides ASCII, Latin-1
or UTF-8 then decoding will always be needed.
=head1 VERSION 2 COMPATIBILITY
When an C<HTML::Parser> object is constructed with no arguments, a set
of handlers is automatically provided that is compatible with the old
HTML::Parser version 2 callback methods.
This is equivalent to the following method calls:
$p->handler(start => "start", "self, tagname, attr, attrseq, text");
$p->handler(end => "end", "self, tagname, text");
$p->handler(text => "text", "self, text, is_cdata");
$p->handler(process => "process", "self, token0, text");
$p->handler(
comment => sub {
my($self, $tokens) = @_;
for (@$tokens) {$self->comment($_);}
},
"self, tokens"
);
$p->handler(
declaration => sub {
my $self = shift;
$self->declaration(substr($_[0], 2, -1));
},
"self, text"
);
Setting up these handlers can also be requested with the "api_version =>
2" constructor option.
=head1 SUBCLASSING
The C<HTML::Parser> class is able to be subclassed. Parser objects are plain
hashes and C<HTML::Parser> reserves only hash keys that start with
"_hparser". The parser state can be set up by invoking the init()
method, which takes the same arguments as new().
=head1 EXAMPLES
The first simple example shows how you might strip out comments from
an HTML document. We achieve this by setting up a comment handler that
does nothing and a default handler that will print out anything else:
use HTML::Parser;
HTML::Parser->new(
default_h => [sub { print shift }, 'text'],
comment_h => [""],
)->parse_file(shift || die) || die $!;
An alternative implementation is:
use HTML::Parser;
HTML::Parser->new(
end_document_h => [sub { print shift }, 'skipped_text'],
comment_h => [""],
)->parse_file(shift || die) || die $!;
This will in most cases be much more efficient since only a single
callback will be made.
The next example prints out the text that is inside the <title>
element of an HTML document. Here we start by setting up a start
handler. When it sees the title start tag it enables a text handler
that prints any text found and an end handler that will terminate
parsing as soon as the title end tag is seen:
use HTML::Parser ();
sub start_handler {
return if shift ne "title";
my $self = shift;
$self->handler(text => sub { print shift }, "dtext");
$self->handler(
end => sub {
shift->eof if shift eq "title";
},
"tagname,self"
);
}
my $p = HTML::Parser->new(api_version => 3);
$p->handler(start => \&start_handler, "tagname,self");
$p->parse_file(shift || die) || die $!;
print "\n";
More examples are found in the F<eg/> directory of the C<HTML-Parser>
distribution: the program C<hrefsub> shows how you can edit all links
found in a document; the program C<htextsub> shows how to edit the text only; the
program C<hstrip> shows how you can strip out certain tags/elements
and/or attributes; and the program C<htext> show how to obtain the
plain text, but not any script/style content.
You can browse the F<eg/> directory online from the I<[Browse]> link on
the http://search.cpan.org/~gaas/HTML-Parser/ page.
=head1 BUGS
The <style> and <script> sections do not end with the first "</", but
need the complete corresponding end tag. The standard behaviour is
not really practical.
When the I<strict_comment> option is enabled, we still recognize
comments where there is something other than whitespace between even
and odd "--" markers.
Once $p->boolean_attribute_value has been set, there is no way to
restore the default behaviour.
There is currently no way to get both quote characters
into the same literal argspec.
Empty tags, e.g. "<>" and "</>", are not recognized. SGML allows them
to repeat the previous start tag or close the previous start tag
respectively.
NET tags, e.g. "code/.../" are not recognized. This is SGML
shorthand for "<code>...</code>".
Incomplete start or end tags, e.g. "<tt<b>...</b</tt>" are not
recognized.
=head1 DIAGNOSTICS
The following messages may be produced by HTML::Parser. The notation
in this listing is the same as used in L<perldiag>:
=over
=item Not a reference to a hash
(F) The object blessed into or subclassed from HTML::Parser is not a
hash as required by the HTML::Parser methods.
=item Bad signature in parser state object at %p
(F) The _hparser_xs_state element does not refer to a valid state structure.
Something must have changed the internal value
stored in this hash element, or the memory has been overwritten.
=item _hparser_xs_state element is not a reference
(F) The _hparser_xs_state element has been destroyed.
=item Can't find '_hparser_xs_state' element in HTML::Parser hash
(F) The _hparser_xs_state element is missing from the parser hash.
It was either deleted, or not created when the object was created.
=item API version %s not supported by HTML::Parser %s
(F) The constructor option 'api_version' with an argument greater than
or equal to 4 is reserved for future extensions.
=item Bad constructor option '%s'
(F) An unknown constructor option key was passed to the new() or
init() methods.
=item Parse loop not allowed
(F) A handler invoked the parse() or parse_file() method.
This is not permitted.
=item marked sections not supported
(F) The $p->marked_sections() method was invoked in a HTML::Parser
module that was compiled without support for marked sections.
=item Unknown boolean attribute (%d)
(F) Something is wrong with the internal logic that set up aliases for
boolean attributes.
=item Only code or array references allowed as handler
(F) The second argument for $p->handler must be either a subroutine
reference, then name of a subroutine or method, or a reference to an
array.
=item No handler for %s events
(F) The first argument to $p->handler must be a valid event name; i.e. one
of "start", "end", "text", "process", "declaration" or "comment".
=item Unrecognized identifier %s in argspec
(F) The identifier is not a known argspec name.
Use one of the names mentioned in the argspec section above.
=item Literal string is longer than 255 chars in argspec
(F) The current implementation limits the length of literals in
an argspec to 255 characters. Make the literal shorter.
=item Backslash reserved for literal string in argspec
(F) The backslash character "\" is not allowed in argspec literals.
It is reserved to permit quoting inside a literal in a later version.
=item Unterminated literal string in argspec
(F) The terminating quote character for a literal was not found.
=item Bad argspec (%s)
(F) Only identifier names, literals, spaces and commas
are allowed in argspecs.
=item Missing comma separator in argspec
(F) Identifiers in an argspec must be separated with ",".
=item Parsing of undecoded UTF-8 will give garbage when decoding entities
(W) The first chunk parsed appears to contain undecoded UTF-8 and one
or more argspecs that decode entities are used for the callback
handlers.
The result of decoding will be a mix of encoded and decoded characters
for any entities that expand to characters with code above 127. This
is not a good thing.
The recommended solution is to apply Encode::decode_utf8() on the data before
feeding it to the $p->parse(). For $p->parse_file() pass a file that has been
opened in ":utf8" mode.
The alternative solution is to enable the C<utf8_mode> and not decode before
passing strings to $p->parse(). The parser can process raw undecoded UTF-8
sanely if the C<utf8_mode> is enabled, or if the C<attr>, C<@attr> or C<dtext>
argspecs are avoided.
=item Parsing string decoded with wrong endian selection
(W) The first character in the document is U+FFFE. This is not a
legal Unicode character but a byte swapped C<BOM>. The result of parsing
will likely be garbage.
=item Parsing of undecoded UTF-32
(W) The parser found the Unicode UTF-32 C<BOM> signature at the start
of the document. The result of parsing will likely be garbage.
=item Parsing of undecoded UTF-16
(W) The parser found the Unicode UTF-16 C<BOM> signature at the start of
the document. The result of parsing will likely be garbage.

=head1 NAME
HTML::PullParser - Alternative HTML::Parser interface
=head1 SYNOPSIS
use HTML::PullParser;
$p = HTML::PullParser->new(file => "index.html",
start => 'event, tagname, @attr',
end => 'event, tagname',
ignore_elements => [qw(script style)],
) || die "Can't open: $!";
while (my $token = $p->get_token) {
#...do something with $token
}
=head1 DESCRIPTION
The HTML::PullParser is an alternative interface to the HTML::Parser class.
It basically turns the HTML::Parser inside out. You associate a file
(or any IO::Handle object or string) with the parser at construction time and
then repeatedly call $parser->get_token to obtain the tags and text
found in the parsed document.
The following methods are provided:
=over 4
=item $p = HTML::PullParser->new( file => $file, %options )
=item $p = HTML::PullParser->new( doc => \$doc, %options )
A C<HTML::PullParser> can be made to parse from either a file or a
literal document based on whether the C<file> or C<doc> option is
passed to the parser's constructor.
The C<file> passed in can either be a file name or a file handle
object. If a file name is passed, and it can't be opened for reading,
then the constructor will return an undefined value and $! will tell
you why it failed. Otherwise the argument is taken to be some object
that the C<HTML::PullParser> can read() from when it needs more data.
The stream will be read() until EOF, but not closed.
A C<doc> can be passed plain or as a reference
to a scalar. If a reference is passed then the value of this scalar
should not be changed before all tokens have been extracted.
Next the information to be returned for the different token types must
be set up. This is done by simply associating an argspec (as defined
in L<HTML::Parser>) with the events you have an interest in. For
instance, if you want C<start> tokens to be reported as the string
C<'S'> followed by the tagname and the attributes you might pass an
C<start>-option like this:
$p = HTML::PullParser->new(
doc => $document_to_parse,
start => '"S", tagname, @attr',
end => '"E", tagname',
);
At last other C<HTML::Parser> options, like C<ignore_tags>, and
C<unbroken_text>, can be passed in. Note that you should not use the
I<event>_h options to set up parser handlers. That would confuse the
inner logic of C<HTML::PullParser>.
=item $token = $p->get_token
This method will return the next I<token> found in the HTML document,
or C<undef> at the end of the document. The token is returned as an
array reference. The content of this array match the argspec set up
during C<HTML::PullParser> construction.
=item $p->unget_token( @tokens )
If you find out you have read too many tokens you can push them back,
so that they are returned again the next time $p->get_token is called.
=back
=head1 EXAMPLES
The 'eg/hform' script shows how we might parse the form section of
HTML::Documents using HTML::PullParser.

HTML::TokeParser - Alternative HTML::Parser interface
=head1 SYNOPSIS
require HTML::TokeParser;
$p = HTML::TokeParser->new("index.html") ||
die "Can't open: $!";
$p->empty_element_tags(1); # configure its behaviour
while (my $token = $p->get_token) {
#...
}
=head1 DESCRIPTION
The C<HTML::TokeParser> is an alternative interface to the
C<HTML::Parser> class. It is an C<HTML::PullParser> subclass with a
predeclared set of token types. If you wish the tokens to be reported
differently you probably want to use the C<HTML::PullParser> directly.
The following methods are available:
=over 4
=item $p = HTML::TokeParser->new( $filename, %opt );
=item $p = HTML::TokeParser->new( $filehandle, %opt );
=item $p = HTML::TokeParser->new( \$document, %opt );
The object constructor argument is either a file name, a file handle
object, or the complete document to be parsed. Extra options can be
provided as key/value pairs and are processed as documented by the base
classes.
If the argument is a plain scalar, then it is taken as the name of a
file to be opened and parsed. If the file can't be opened for
reading, then the constructor will return C<undef> and $! will tell
you why it failed.
If the argument is a reference to a plain scalar, then this scalar is
taken to be the literal document to parse. The value of this
scalar should not be changed before all tokens have been extracted.
Otherwise the argument is taken to be some object that the
C<HTML::TokeParser> can read() from when it needs more data. Typically
it will be a filehandle of some kind. The stream will be read() until
EOF, but not closed.
A newly constructed C<HTML::TokeParser> differ from its base classes
by having the C<unbroken_text> attribute enabled by default. See
L<HTML::Parser> for a description of this and other attributes that
influence how the document is parsed. It is often a good idea to enable
C<empty_element_tags> behaviour.
Note that the parsing result will likely not be valid if raw undecoded
UTF-8 is used as a source. When parsing UTF-8 encoded files turn
on UTF-8 decoding:
open(my $fh, "<:utf8", "index.html") || die "Can't open 'index.html': $!";
my $p = HTML::TokeParser->new( $fh );
# ...
If a $filename is passed to the constructor the file will be opened in
raw mode and the parsing result will only be valid if its content is
Latin-1 or pure ASCII.
If parsing from an UTF-8 encoded string buffer decode it first:
utf8::decode($document);
my $p = HTML::TokeParser->new( \$document );
# ...
=item $p->get_token
This method will return the next I<token> found in the HTML document,
or C<undef> at the end of the document. The token is returned as an
array reference. The first element of the array will be a string
denoting the type of this token: "S" for start tag, "E" for end tag,
"T" for text, "C" for comment, "D" for declaration, and "PI" for
process instructions. The rest of the token array depend on the type
like this:
["S", $tag, $attr, $attrseq, $text]
["E", $tag, $text]
["T", $text, $is_data]
["C", $text]
["D", $text]
["PI", $token0, $text]
where $attr is a hash reference, $attrseq is an array reference and
the rest are plain scalars. The L<HTML::Parser/Argspec> explains the
details.
=item $p->unget_token( @tokens )
If you find you have read too many tokens you can push them back,
so that they are returned the next time $p->get_token is called.
=item $p->get_tag
=item $p->get_tag( @tags )
This method returns the next start or end tag (skipping any other
tokens), or C<undef> if there are no more tags in the document. If
one or more arguments are given, then we skip tokens until one of the
specified tag types is found. For example:
$p->get_tag("font", "/font");
will find the next start or end tag for a font-element.
The tag information is returned as an array reference in the same form
as for $p->get_token above, but the type code (first element) is
missing. A start tag will be returned like this:
[$tag, $attr, $attrseq, $text]
The tagname of end tags are prefixed with "/", i.e. end tag is
returned like this:
["/$tag", $text]
=item $p->get_text
=item $p->get_text( @endtags )
This method returns all text found at the current position. It will
return a zero length string if the next token is not text. Any
entities will be converted to their corresponding character.
If one or more arguments are given, then we return all text occurring
before the first of the specified tags found. For example:
$p->get_text("p", "br");
will return the text up to either a paragraph of line break element.
The text might span tags that should be I<textified>. This is
controlled by the $p->{textify} attribute, which is a hash that
defines how certain tags can be treated as text. If the name of a
start tag matches a key in this hash then this tag is converted to
text. The hash value is used to specify which tag attribute to obtain
the text from. If this tag attribute is missing, then the upper case
name of the tag enclosed in brackets is returned, e.g. "[IMG]". The
hash value can also be a subroutine reference. In this case the
routine is called with the start tag token content as its argument and
the return value is treated as the text.
The default $p->{textify} value is:
{img => "alt", applet => "alt"}
This means that <IMG> and <APPLET> tags are treated as text, and that
the text to substitute can be found in the ALT attribute.
=item $p->get_trimmed_text
=item $p->get_trimmed_text( @endtags )
Same as $p->get_text above, but will collapse any sequences of white
space to a single space character. Leading and trailing white space is
removed.
=item $p->get_phrase
This will return all text found at the current position ignoring any
phrasal-level tags. Text is extracted until the first non
phrasal-level tag. Textification of tags is the same as for
get_text(). This method will collapse white space in the same way as
get_trimmed_text() does.
The definition of <i>phrasal-level tags</i> is obtained from the
HTML::Tagset module.
=back
=head1 EXAMPLES
This example extracts all links from a document. It will print one
line for each link, containing the URL and the textual description
between the <A>...</A> tags:
use HTML::TokeParser;
$p = HTML::TokeParser->new(shift||"index.html");
while (my $token = $p->get_tag("a")) {
my $url = $token->[1]{href} || "-";
my $text = $p->get_trimmed_text("/a");
print "$url\t$text\n";
}
This example extract the <TITLE> from the document:
use HTML::TokeParser;
$p = HTML::TokeParser->new(shift||"index.html");
if ($p->get_tag("title")) {
my $title = $p->get_trimmed_text;
print "Title: $title\n";
}

=head1 NAME
HTML::HeadParser - Parse <HEAD> section of a HTML document
=head1 SYNOPSIS
require HTML::HeadParser;
$p = HTML::HeadParser->new;
$p->parse($text) and print "not finished";
$p->header('Title') # to access <title>....</title>
$p->header('Content-Base') # to access <base href="http://...">
$p->header('Foo') # to access <meta http-equiv="Foo" content="...">
$p->header('X-Meta-Author') # to access <meta name="author" content="...">
$p->header('X-Meta-Charset') # to access <meta charset="...">
=head1 DESCRIPTION
The C<HTML::HeadParser> is a specialized (and lightweight)
C<HTML::Parser> that will only parse the E<lt>HEAD>...E<lt>/HEAD>
section of an HTML document. The parse() method
will return a FALSE value as soon as some E<lt>BODY> element or body
text are found, and should not be called again after this.
Note that the C<HTML::HeadParser> might get confused if raw undecoded
UTF-8 is passed to the parse() method. Make sure the strings are
properly decoded before passing them on.
The C<HTML::HeadParser> keeps a reference to a header object, and the
parser will update this header object as the various elements of the
E<lt>HEAD> section of the HTML document are recognized. The following
header fields are affected:
=over 4
=item Content-Base:
The I<Content-Base> header is initialized from the E<lt>base
href="..."> element.
=item Title:
The I<Title> header is initialized from the E<lt>title>...E<lt>/title>
element.
=item Isindex:
The I<Isindex> header will be added if there is a E<lt>isindex>
element in the E<lt>head>. The header value is initialized from the
I<prompt> attribute if it is present. If no I<prompt> attribute is
given it will have '?' as the value.
=item X-Meta-Foo:
All E<lt>meta> elements containing a C<name> attribute will result in
headers using the prefix C<X-Meta-> appended with the value of the
C<name> attribute as the name of the header, and the value of the
C<content> attribute as the pushed header value.
E<lt>meta> elements containing a C<http-equiv> attribute will result
in headers as in above, but without the C<X-Meta-> prefix in the
header name.
E<lt>meta> elements containing a C<charset> attribute will result in
an C<X-Meta-Charset> header, using the value of the C<charset>
attribute as the pushed header value.
The ':' character can't be represented in header field names, so
if the meta element contains this char it's substituted with '-'
before forming the field name.

=head1 METHODS
The following methods (in addition to those provided by the
superclass) are available:

=item $hp = HTML::HeadParser->new
=item $hp = HTML::HeadParser->new( $header )
The object constructor. The optional $header argument should be a
reference to an object that implement the header() and push_header()
methods as defined by the C<HTTP::Headers> class. Normally it will be
of some class that is a or delegates to the C<HTTP::Headers> class.
If no $header is given C<HTML::HeadParser> will create an
C<HTTP::Headers> object by itself (initially empty).

14. Proposed Entities
The HTML DTD references the "Added Latin 1" entity set, which only
supplies named entities for a subset of the non-ASCII characters in
[ISO-8859-1], namely the accented characters. The following entities
should be supported so that all ISO 8859-1 characters may only be
referenced symbolically. The names for these entities are taken from
the appendixes of [SGML].
