=head1 NAME
XML::LibXML::Schema - XML Schema Validation
=head1 SYNOPSIS
use XML::LibXML;
$doc = XML::LibXML->new->parse_file($url);
$xmlschema = XML::LibXML::Schema->new( location => $filename_or_url );
$xmlschema = XML::LibXML::Schema->new( string => $xmlschemastring );
eval { $xmlschema->validate( $doc ); };
=head1 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. As of 2.6.32, libxml2 only supports decimal types up to 24 digits
(the standard requires at least 18).
=head1 METHODS
=over 4
=item 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.
=item 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 L<<<<<< XML::LibXML::Document >>>>>> 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.
