NAME

XML::LibXML::Schema - XML Schema Validation

SYNOPSIS

$xmlschema = XML::LibXML::Schema->new( location => $filename_or_url );
$xmlschema = XML::LibXML::Schema->new( string => $xmlschemastring );
eval { $xmlschema->validate( $doc ); };

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.

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 document against the given XML Schema. 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.
