virtual void | normalize ()=0
| Puts all `DOMText` nodes in the full depth of the sub-tree underneath this `DOMNode`, including attribute nodes, into a "normal" form where only markup (e.g., tags, comments, processing instructions, CDATA sections, and entity references) separates `DOMText` nodes, i.e., there are neither adjacent `DOMText` nodes nor empty `DOMText` nodes.

| Compares the reference node, i.e.
virtual const XMLCh * | getTextContent () const =0
| WARNING: This method is known to be buggy and does not produce accurate results under a variety of conditions.
virtual void | setTextContent (const XMLCh *textContent)=0
| This attribute removes any possible children this node may have and, if the new string is not empty or null, replaced by a single `DOMText` node containing the string this attribute is set to.
virtual const XMLCh * | lookupPrefix (const XMLCh *namespaceURI) const =0
| Look up the prefix associated to the given namespace URI, starting from this node.
virtual bool | isDefaultNamespace (const XMLCh *namespaceURI) const =0

## Detailed Description

The `DOMXPathNamespace` interface is returned by `DOMXPathResult` interfaces to represent the XPath namespace node type that DOM lacks.

There is no public constructor for this node type. Attempts to place it into a hierarchy or a NamedNodeMap result in a DOMException with the code HIERARCHY_REQUEST_ERR. This node is read only, so methods or setting of attributes that would mutate the node result in a `DOMException` with the code NO_MODIFICATION_ALLOWED_ERR. The core specification describes attributes of the `DOMNode` interface that are different for different node types but does not describe XPATH_NAMESPACE_NODE, so here is a description of those attributes for this node type. All attributes of `DOMNode` not described in this section have a null or false value. ownerDocument matches the ownerDocument of the ownerElement even if the element is later adopted. nodeName is always the string "#namespace". prefix is the prefix of the namespace represented by the node. localName is the same as prefix. nodeType is equal to XPATH_NAMESPACE_NODE. namespaceURI is the namespace URI of the namespace represented by the node. nodeValue is the same as namespaceURI. adoptNode, cloneNode, and importNode fail on this node type by raising a DOMException with the code NOT_SUPPORTED_ERR. Note: In future versions of the XPath specification, the definition of a namespace node may be changed incompatibly, in which case incompatible changes to field values may be required to implement versions beyond XPath 1.0.

## Constructor & Destructor Documentation

## DOMXPathNamespace()

## ~DOMXPathNamespace()

Destructor.

## Member Function Documentation

## getOwnerElement()

virtual DOMElement * DOMXPathNamespace::getOwnerElement | ( |  | ) | const

pure virtual

The `DOMElement` on which the namespace was in scope when it was requested.

This does not change on a returned namespace node even if the document changes such that the namespace goes out of scope on that element and this node is no longer found there by XPath.
