RDF::Core::Parser

RDF::Core::Parser - RDF Parser


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. 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.


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);

Interface

  • new(%options)
  • Available options are
    • Assert
    • A reference to a subroutine, that is called for every assertion that parser generates.

    • BaseURI
    • A base URI of parsed document. It will be used to resolve relative URI references.

    • BNodePrefix
    • Blank node identifier is generated as ``_:'' concatenated with BNodePrefix value concatenated with counter number. Default BnodePrefix is ``a''.

    • InlineURI
    • Deprecated.

  • parse($string)
  • parseFile($fileName)

Assert handler

Assert handler is called with key value pairs in a parameters array.

Keys are:
