RdfXmlParser
in package
implements ParserInterface, QuadIteratorInterface uses CreateBlankNodeTrait, TmpStreamParserTrait

Streaming RDF-XML parser. Fast and with low memory footprint.

Known deviations from the RDF-XML specification:

  • Doesn't resolve "/.." in relative IRIs.
  • Doesn't support rdf:Seq shorthand syntax
  • Doesn't support rdf:Collection shorthand syntax

Methods

parseStream()

public parseStream(resource|StreamInterface $input[, string $baseUri = '' ]) : QuadIteratorInterface
Parameters
$input : resource|StreamInterface
$baseUri : string = ''

allows to specify the base URI of the parsed document so a parser can correctly determine which blank nodes belong to the same document (see also the BLANK_NODES_PRESERVE constant)

QuadIteratorInterface
