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:

        *   $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:

        *   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.
