XML Schema Validation

Synopsis

use XML::LibXML;
$doc = XML::LibXML->new->parse_file($url);

Description
The XML::LibXML::Schema class is a tiny frontend to libxml2's XML Schema implementation. Currently it supports only schema parsing and document validation.

Methods
new 	

$xmlschema = XML::LibXML::Schema->new( location => $filename_or_url );
$xmlschema = XML::LibXML::Schema->new( string => $xmlschemastring );

The constructor of XML::LibXML::Schema may get called with either one of two parameters. The parameter tells the class from which source it should generate a validation schema. It is important, that each schema only have a single source.
The location parameter allows to parse a schema from the filesystem or a URL.
The string parameter will parse the schema from the given XML string.
Note that the constructor will die() if the schema does not meed the constraints of the XML Schema specification.
validate 	

eval { $xmlschema->validate( $doc ); };

This function allows to validate a (parsed) document against the given XML Schema. The argument of this function should be a XML::LibXML DOM Document Class object. If this function succeeds, it will return 0, otherwise it will die() and report the errors found. Because of this validate() should be always evaluated.
