XML-Struct - Represent XML as data structure preserving element order
SYNOPSIS
use XML::Struct qw(readXML writeXML simpleXML removeXMLAttr);
my $xml = readXML( "input.xml" );
# [ root => { xmlns => 'http://example.org/' }, [ '!', [ x => {}, [42] ] ] ]
my $doc = writeXML( $xml );
#
# !42
my $simple = simpleXML( $xml, root => 'record' );
# { record => { xmlns => 'http://example.org/', x => 42 } }
my $xml2 = removeXMLAttr($xml);
# [ root => [ '!', [ x => [42] ] ] ]
DESCRIPTION
XML::Struct implements a mapping between XML and Perl data structures.
By default, the mapping preserves element order, so it also suits for
"document-oriented" XML. In short, an XML element is represented as
array reference with three parts:
[ $name => \%attributes, \@children ]
This data structure corresponds to the abstract data model of MicroXML
, a simplified subset of XML.
If your XML documents don't contain relevant attributes, you can also
choose to map to this format:
[ $name => \@children ]
Both parsing (with XML::Struct::Reader or function readXML) and
serializing (with XML::Struct::Writer or function writeXML) are fully
based on XML::LibXML, so performance is better than XML::Simple and
similar to XML::LibXML::Simple.
MODULES
XML::Struct::Reader
Parse XML as stream into XML data structures.
XML::Struct::Writer
Write XML data structures to XML streams for serializing, SAX
processing, or creating a DOM object.
XML::Struct::Writer::Stream
Simplified SAX handler for XML serialization.
XML::Struct::Simple
Transform XML data structure into simple form.
FUNCTIONS
The following functions are exported on request:
readXML( $source [, %options ] )
Read an XML document with XML::Struct::Reader. The type of source
(string, filename, URL, IO Handle...) is detected automatically.
Options not known to XML::Struct::Reader are passed to
XML::LibXML::Reader.
writeXML( $xml [, %options ] )
Write an XML document/element with XML::Struct::Writer.
simpleXML( $element [, %options ] )
Transform an XML document/element into simple key-value format as known
from XML::Simple. See XML::Struct::Simple for configuration options.
removeXMLAttr( $element )
Transform XML structure with attributes to XML structure without
attributes. The function does not modify the passed element but creates
a modified copy.
EXAMPLE
To give an example, with XML::Struct::Reader, this XML document:
text
text
is transformed to this structure:
[
"root", { }, [
[ "foo", { }, "text" ],
[ "bar", { key => "value" }, [
"text",
[ "doz", { }, [ ] ]
]
]
]
This module also supports a simple key-value (aka "data-oriented")
format, as used by XML::Simple. With option simple (or function
simpleXML) the document given above would be transformed to this
structure:
{
foo => "text",
bar => {
key => "value",
doz => {}
}
}
SEE ALSO
This module was first created to be used in Catmandu::XML and turned
out to also become a replacement for XML::Simple. See the former for
more XML processing.
XML::Twig is another popular and powerfull module for stream-based
processing of XML documents.
See XML::Smart, XML::Hash::LX, XML::Parser::Style::ETree, XML::Fast,
and XML::Structured for different representations of XML data as data
structures (feel free to implement converters from/to XML::Struct).
XML::GenericJSON seems to be an outdated and incomplete attempt to
capture more parts of XML Infoset in another data structure.
See JSONx for a kind of reverse direction (JSON in XML).

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.
Copyright (C) 19yy
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
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.

my $xml = readXML( "input.xml" );
# [ root => { xmlns => 'http://example.org/' }, [ '!', [ x => {}, [42] ] ] ]

# [ root => [ '!', [ x => [42] ] ] ]
=head1 DESCRIPTION
L implements a mapping between XML and Perl data structures. By
default, the mapping preserves element order, so it also suits for
"document-oriented" XML. In short, an XML element is represented as array
reference with three parts:
[ $name => \%attributes, \@children ]
This data structure corresponds to the abstract data model of
L, a simplified subset of XML.
If your XML documents don't contain relevant attributes, you can also choose
to map to this format:
[ $name => \@children ]
Both parsing (with L or function C) and
serializing (with L or function C) are fully
based on L, so performance is better than L and
similar to L.
=head1 MODULES
=over
=item L
Parse XML as stream into XML data structures.
=item L
Write XML data structures to XML streams for serializing, SAX processing, or
creating a DOM object.
=item L
Simplified SAX handler for XML serialization.
=item L
Transform XML data structure into simple form.
=back
=head1 FUNCTIONS
The following functions are exported on request:
=head2 readXML( $source [, %options ] )
Read an XML document with L. The type of source (string,
filename, URL, IO Handle...) is detected automatically. Options not known to
XML::Struct::Reader are passed to L.
=head2 writeXML( $xml [, %options ] )
Write an XML document/element with L.
=head2 simpleXML( $element [, %options ] )
Transform an XML document/element into simple key-value format as known from
L. See L for configuration options.
=head2 removeXMLAttr( $element )
Transform XML structure with attributes to XML structure without attributes.
The function does not modify the passed element but creates a modified copy.
=head1 EXAMPLE
To give an example, with L, this XML document:
text
text
is transformed to this structure:
[
"root", { }, [
[ "foo", { }, "text" ],
[ "bar", { key => "value" }, [
"text",
[ "doz", { }, [ ] ]
]
]
]
This module also supports a simple key-value (aka "data-oriented") format, as
used by L. With option C (or function C) the
document given above would be transformed to this structure:
{
foo => "text",
bar => {
key => "value",
doz => {}
}
}
=head1 SEE ALSO
This module was first created to be used in L and turned out to
also become a replacement for L. See the former for more XML
processing.
L is another popular and powerfull module for stream-based
processing of XML documents.
See L, L, L,
L, and L for different representations of XML data
as data structures (feel free to implement converters from/to XML::Struct).
L seems to be an outdated and incomplete attempt to capture
more parts of XML Infoset in another data structure.
See JSONx for a kind of reverse direction (JSON in XML).

XML::Struct::Simple - Transform MicroXML data structures into simple (unordered) form
=head1 SYNOPSIS
my $micro = [
root => { xmlns => 'http://example.org/' },
[ '!', [ x => {}, [42] ] ]
];
my $converter = XML::Struct::Simple->new( root => 'record' );
my $simple = $converter->transform( $micro );
# { record => { xmlns => 'http://example.org/', x => 42 } }
=head1 DESCRIPTION
This module implements a transformation from structured XML (MicroXML) to
simple key-value format (SimpleXML) as known from L: Attributes
and child elements are treated as hash keys with their content as value. Text
elements without attributes are converted to text and empty elements without
attributes are converted to empty hashes.
L can export the function C for easy use. Function
C and L apply transformation to SimpleXML with
option C.
=head1 METHODS
=head2 transform( $element )
Transform XML given as array reference (MicroXML) to XML as hash reference
(SimpleXML) as configured.
=head2 transform_content( $element [, $depth ] )
Transform child nodes and attributes of an XML element given as array reference
at a given depth (C<0> by default). Returns a hash reference, a scalar, or the
element unmodified.
=head1 CONFIGURATION
=over
=item root
Keep the root element instead of removing. This corresponds to option
C in L. In addition a non-numeric value can be used to
override the name of the root element. Disabled by default.
=item attributes
Include XML attributes. Enabled by default. The special value C is
equivalent to false. Corresponds to option C in L.
=item content
Name of a field to put text content in. Set to "C by default.
Corresponds to option C in L.
=item depth
Only transform up to a given depth. Set to a negative value by default for
unlimited depth. Elements below depth are not cloned but copied by reference.
Depth 0 will return the element unmodified.
=back
Option C, C, and other fetures of L not
supported. Options C and C supported in
L are not supported yet.
=head2 FUNCTIONS
=head2 removeXMLAttr( $element )
Recursively remove XML attributes from XML given as array reference (MicroXML).
This function is deprecated.

=head1 NAME
XML::Struct::Reader - Read XML streams into XML data structures
=head1 SYNOPSIS
my $reader = XML::Struct::Reader->new( from => "file.xml" );
my $data = $reader->read;
=head1 DESCRIPTION
This module reads an XML stream (via L) into
L/MicroXML data structures.
=head1 METHODS
=head2 read = readNext ( [ $stream ] [, $path ] )
Read the next XML element from a stream. If no path option is specified, the
reader's path option is used ("C<*>" by default, first matching the root, then
every other element).
=head2 readDocument( [ $stream ] [, $path ] )
Read an entire XML document. In contrast to C/C, this method
always reads the entire stream. The return value is the first element (that is
the root element by default) in scalar context and a list of elements in array
context. Multiple elements can be returned for instance when a path was
specified to select document fragments.
=head2 readElement( [ $stream ] )
Read an XML element from a stream and return it as array reference with element name,
attributes, and child elements. In contrast to method C, this method expects
the stream to be at an element node (C<< $stream->nodeType == 1 >>) or bad things
might happed.
=head2 readAttributes( [ $stream ] )
Read all XML attributes from a stream and return a (possibly empty) hash
reference.
=head2 readContent( [ $stream ] )
Read all child elements of an XML element and return the result as (possibly
empty) array reference. Significant whitespace is only included if option
C is enabled.
=head1 CONFIGURATION
=over
=item from
A source to read from. Possible values include a string or string reference
with XML data, a filename, an URL, a file handle, instances of
L or L, and a hash reference with
options passed to L.
=item stream
A L to read from. If no stream has been defined, one must
pass a stream parameter to the C methods. Setting a source with option
C automatically sets a stream.
=item attributes
Include attributes (enabled by default). If disabled, the representation of
an XML element will be
[ $name => \@children ]
instead of
[ $name => \%attributes, \@children ]
=item path
Optional path expression to be used as default value when calling C.
Pathes must either be absolute (starting with "C") or consist of a single
element name. The special name "C<*>" matches all element names.
A path is a very reduced form of an XPath expressions (no axes, no "C<..>", no
node tests, C only at the start...). Namespaces are not supported yet.
=item whitespace
Include ignorable whitespace as text elements (disabled by default)
=item ns
Define how XML namespaces should be processed. By default (value 'C'),
this document:
is transformed to this structure, keeping namespace prefixes and declarations
as unprocessed element names and attributes:
[ 'doc', {}, [
[
'x:foo', {
'bar' => 'doz',
'xmlns:x' => 'http://example.org/'
}
]
]
Setting this option to 'C' will remove all namespace prefixes and
namespace declaration attributes, so the result would be:
[ 'doc', {}, [
[
'foo', {
'bar' => 'doz'
}
]
]
Setting this option to 'C' results in an error when namespace
prefixes or declarations are read.
Expanding namespace URIs ('C) is not supported yet.
=item simple
Convert XML to simple key-value structure (SimpleXML) with
L.
=item depth
Only transform to a given depth, starting at C<0> for the root node. Negative
values, non-numeric values or C are ignored (unlimited depth as
default).
XML elements below the depth are converted to SimpleXML by default or to
MicroXML if option C is enabled. This can be configured with option
C.
This option is useful for instance to access document-oriented XML embedded in
data oriented XML.
=item deep
How to transform elements below given C. This option is experimental.
=item root
Include root element when converting to SimpleXML. Disabled by default.
=item content
Name of text content when converting to SimpleXML.

=head1 NAME
XML::Struct::Writer - Write XML data structures to XML streams
=head1 SYNOPSIS
use XML::Struct::Writer;
# serialize
XML::Struct::Writer->new(
to => \*STDOUT,
attributes => 0,
pretty => 1,
)->write( [
doc => [
[ name => [ "alice" ] ],
[ name => [ "bob" ] ],
]
] );
#
#
# alice
# bob
#
# create DOM
my $xml = XML::Struct::Writer->new->write( [
greet => { }, [
"Hello, ",
[ emph => { color => "blue" } , [ "World" ] ],
"!"
]
] );
$xml->toFile("greet.xml");
#
# Hello, World!
=head1 DESCRIPTION
This module writes an XML document, given as L data structure, as
stream of L. The default handler receives these events with
L to build a DOM tree which can then be used to
serialize the XML document as string. The writer can also be used to directly
serialize XML with L.
L provides the shortcut function C to this module.
XML elements can be passed in any of these forms and its combinations:
# MicroXML:
[ $name => \%attributes, \@children ]
[ $name => \%attributes ]
[ $name ]
# lax MicroXML also:
[ $name => \@children ]
# SimpleXML:
{ $name => \@children, $name => $content, ... }
=head1 CONFIGURATION
A XML::Struct::Writer can be configured with the following options:
=over
=item to
Filename, L, string reference, or other kind of stream to directly
serialize XML to with L. This option is ignored
if C is explicitly set.
=item handler
A SAX handler to send L to. If neither this option nor C is
explicitly set, an instance of L is used to build a
DOM.
=item attributes
Ignore XML attributes if set to false. Set to true by default.
=item xmldecl
Include XML declaration on serialization. Enabled by default.
=item encoding
An encoding (for handlers that support an explicit encoding). Set to UTF-8
by default.
=item version
The XML version. Set to C<1.0> by default.
=item standalone
Add standalone flag in the XML declaration.
=item pretty
Pretty-print XML. Disabled by default.
=back
=head1 METHODS
=head2 write( $root [, $name ] ) == writeDocument( $root [, $name ] )
Write an XML document, given as array reference (lax MicroXML), hash reference
(SimpleXML), or both mixed. If given as hash reference, the name of a root tag
can be chosen or it is set to C. This method is basically equivalent to:
$writer->writeStart;
$writer->writeElement(
$writer->microXML($root, $name // 'root')
);
$writer->writeEnd;
$writer->result if $writer->can('result');
The remaining methods expect XML in MicroXML format only.
=head2 writeElement( $element [, @more_elements ] )
Write one or more XML elements and their child elements to the handler.
=head2 writeStart( [ $root [, $name ] ] )
Call the handler's C and C methods. An optional root
element can be passed, so C<< $writer->writeStart($root) >> is equivalent to:
$writer->writeStart;
$writer->writeStartElement($root);
=head2 writeStartElement( $element )
Directly call the handler's C method.
=head2 writeEndElement( $element )
Directly call the handler's C method.
=head2 writeCharacters( $string )
Directy call the handler's C method.
=head2 writeEnd( [ $root ] )
Directly call the handler's C method. An optional root element
can be passed, so C<< $writer->writeEnd($root) >> is equivalent to:
$writer->writeEndElement($root);
$writer->writeEnd;
=head2 microXML( $element [, $name ] )
Convert an XML element, given as array reference (lax MicroXML) or as hash
reference (SimpleXML) to a list of MicroXML elements and optionally remove
attributes. Does not affect child elements.
=head1 SAX EVENTS
A SAX handler, set with option C, is expected to implement the
following methods (two of them are optional):
=over
=item xml_decl( { Version => $version, Encoding => $encoding } )
Optionally called once at the start of an XML document, if the handler supports
this method.
=item start_document()
Called once at the start of an XML document.
=item start_element( { Name => $name, Attributes => \%attributes } )
Called at the start of an XML element to emit an XML start tag.
=item end_element( { Name => $name } )
Called at the end of an XML element to emit an XML end tag.
=item characters( { Data => $characters } )
Called for character data. Character entities and CDATA section are expanded to
strings.
=item end_document()
Called once at the end of an XML document.
=item result()
Optionally called at the end of C/C to return a value
from this methods. Handlers do not need to implement this method.

=head1 SEE ALSO
Using a streaming SAX handler, such as L,
L, L, and possibly L
should be more performant for serialization. Examples of other modules that
receive SAX events include L, L, and
L,
