XML::LibXML::RelaxNG3pm

Usage

  use XML::LibXML;
  $doc = XML::LibXML->new->parse_file($url);
  $rngschema = XML::LibXML::RelaxNG->new( location => $filename_or_url, no_network => 1 );
  $rngschema = XML::LibXML::RelaxNG->new( string => $xmlschemastring, no_network => 1 );
  $rngschema = XML::LibXML::RelaxNG->new( DOM => $doc, no_network => 1 );
  eval { $rngschema->validate( $doc ); };

Overview

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, no_network => 1 );
  $rngschema = XML::LibXML::RelaxNG->new( string => $xmlschemastring, no_network => 1 );
  $rngschema = XML::LibXML::RelaxNG->new( DOM => $doc, no_network => 1 );

The constructor of XML::LibXML::RelaxNG needs to be called with list of parameters. At least location, string or DOM parameter is required to specify source of schema. Optional parameter no_network set to 1 cause that parser would not access network and optional parameter recover set 1 cause that parser would not call die() on errors.

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 (non-HTTPS) 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.
