RDF::Core::Parser - RDF Parser
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. CAUTION: If you parse more documents into one model, you need to set distinct BNodePrefix (see below) for each document. This way you avoid mixing anonymous resources from distinct documents together.
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);
Available options are
A reference to a subroutine, that is called for every assertion that parser generates.
A base URI of parsed document. It will be used to resolve relative URI references.
Blank node identifier is generated as "_:" concatenated with BNodePrefix value concatenated with counter number. Default BnodePrefix is "a".
Assert handler is called with key value pairs in a parameters array.
subject_ns, subject_name, subject_uri
namespace, local value and URI of subject
predicate_ns, predicate_name, predicate_uri
namespace, local value and URI of predicate
object_ns, object_name, object_uri
