NAME
    XML::LibXML::RelaxNG - RelaxNG Schema Validation

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

      $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.

METHODS
    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 one 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 one to parse the schema from a pre-parsed 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 one to validate a (parsed) document against the given RelaxNG schema.
        The argument of this function should be an 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.
