NAME

RDF::Core::Parser - RDF Parser

DESCRIPTION

A module for parsing XML documents containing RDF data. It's based on XML::Parser. Parser goes through XML and calls what is referenced in Assert option for each statement found.

SYNOPSIS

  require RDF::Core::Parser;

  my %options = (Assert => \&handleAssert,
                 BaseURI => "http://www.foo.com/",
                 BNodePrefix => "genid"
                );
  my $parser = new RDF::Core::Parser(%options);
  $parser->parseFile('./rdfFile.xml');
  #or
  $parser->parse($rdfString);
