XPath::Node(3) User Contributed Perl Documentation XPath::Node(3)
NAME
XML::XPath::Node - internal representation of a node
API
The Node API aims to emulate DOM to some extent, however the API isn't quite compatible with DOM. This is to ease transition from XML::DOM
programming to XML::XPath. Compatibility with DOM may arise once XML::DOM gets namespace support.
new
Creates a new node. See the sub-classes for parameters to pass to new().
getNodeType
Returns one of ELEMENT_NODE, TEXT_NODE, COMMENT_NODE, ATTRIBUTE_NODE, PROCESSING_INSTRUCTION_NODE or NAMESPACE_NODE. UNKNOWN_NODE is
returned if the sub-class doesn't implement getNodeType - but that means something is broken! The constants are exported by default from
XML::XPath::Node. The constants have the same numeric value as the XML::DOM versions.
getParentNode
Returns the parent of this node, or undef if this is the root node. Note that the root node is the root node in terms of XPath - not the
root element node.
to_sax ( $handler | %handlers )
Generates sax calls to the handler or handlers. See the PerlSAX docs for details (not yet implemented correctly).
MORE INFO
See the sub-classes for the meaning of the rest of the API:
o XML::XPath::Node::Element
o XML::XPath::Node::Attribute
o XML::XPath::Node::Namespace
o XML::XPath::Node::Text
o XML::XPath::Node::Comment
o XML::XPath::Node::PI
