NAME

       RDF::Query::Node::Literal - RDF Node class for literals

VERSION

       This document describes RDF::Query::Node::Literal version 2.908.

METHODS

       Beyond the methods documented below, this class inherits methods from the RDF::Query::Node and RDF::Trine::Node::Literal classes.

       "datetime"
	   Returns a DateTime object from the literal if the literal value is in W3CDTF format.

       "as_sparql"
	   Returns the SPARQL string for this node.

       "as_hash"
	   Returns the query as a nested set of plain data structures (no objects).

       "is_simple_literal"
	   Returns true if the literal is "simple" -- is a literal without datatype or language.

       "is_numeric_type"
	   Returns true if the literal is a known (xsd) numeric type.

       "numeric_value"
	   Returns the numeric value of the literal (even if the literal isn't a known numeric type.

       "type_list"
	   Returns a two-item list suitable for use as the second and third arguments to RDF::Query::Node::Literal constructor. The two returned
	   values correspond to literal language tag and literal datatype URI, respectively.

NAME

       RDF::Trine::Node::Literal::XML - RDF Node class for XMLLiterals

METHODS

       "new ( $node )"
       "new ( $string [ , $lang, $datatype ] )"
	   Returns a new XML Literal object. This method can be used in two different ways: It can either be passed a string or an XML::LibXML
	   node.

	   In the case of passing a string, this method follows the same API as the RDF::Trine::Node::Literal constructor, but:

	   o   $string must be a well-balanced XML fragment =item * $lang is optional, but if a language code is present it will be used as the
	       value of "xml:lang" attribute(s) on the root XML element(s) of the literal. If the element already has an "xml:lang" attribute it
	       will be overwritten. For the node types that doesn't support adding a language, text and CData, a warning will be issued.  =item *
	       $datatype will be ignored and set to 'http://www.w3.org/1999/02/22-rdf-syntax-ns#XMLLiteral'

	   In the case of using a XML::LibXML node $node, the Node may be one of these types or a subclass thereof:

	   o   XML::LibXML::Document =item * XML::LibXML::DocumentFragment =item * XML::LibXML::Element =item * XML::LibXML::CDATASection =item *
	       XML::LibXML::NodeList =item * XML::LibXML::Text

	   If the string is not a valid XML fragment, and the $node is not of one of the above types, this method throws a RDF::Trine::Error
	   exception.

       "xml_element"
	   Returns the XML::LibXML node for the XML Literal.
