## 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 incomatibly, in which case incompatible changes to field values may be required to implement versions beyond XPath 1.0.

Since:
  DOM Level 3

## Member Enumeration Documentation

enum DOMXPathNamespace::XPathNodeType

Enumerator:

  XPATH_NAMESPACE_NODE |

## Constructor & Destructor Documentation

DOMXPathNamespace::DOMXPathNamespace | ( |  | ) | `[protected]`

virtual DOMXPathNamespace::~DOMXPathNamespace | ( |  | ) | `[virtual]`

Destructor.

## Member Function Documentation

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.

Since:
  DOM Level 3
