XML::LibXML::RelaxNG(3)
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.
