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 );
# <?xml version="1.0" encoding="UTF-8"?>
# <root xmlns="http://example.org/">!<x>42</x></root>
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 <http://www.w3.org/community/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:
<root> <foo>text</foo> <bar key="value"> text <doz/> </bar> </root>
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 => {} } }
