NAME ^

XML::LibXML::RelaxNG - RelaxNG Schema Validation

SYNOPSIS ^

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

DESCRIPTION ^

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

new
  $rngschema = XML::LibXML::RelaxNG->new( location => $filename_or_url );
  $rngschema = XML::LibXML::RelaxNG->new( string => $xmlschemastring );
  $rngschema = XML::LibXML::RelaxNG->new( DOM => $doc );

The constructor of XML::LibXML::RelaxNG may get called with either one of three 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.

The DOM parameter allows to parse the schema from a preparsed XML::LibXML::Document.

Note that the constructor will die() if the schema does not meed the constraints of the RelaxNG specification.

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

This function allows to validate a document against the given RelaxNG 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.
