Interface XPathNamespace

All Superinterfaces:
Node

public interface XPathNamespace
extends Node

DOM Level 3 WD Experimental: The DOM Level 3 specification is at the stage of Working Draft, which represents work in progress and thus may be updated, replaced, or obsoleted by other documents at any time.

The XPathNamespace interface is returned by XPathResult 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 Node interface that are different for different node node types but does not describe XPATH_NAMESPACE_NODE, so here is a description of those attributes for this node type. All attributes of Node 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.

prefix is the prefix of the namespace represented by the node.

nodeName is the same as prefix.

nodeType is equal to XPATH_NAMESPACE_NODE.

namespaceURI is the namespace URI of the namespace represented by the node.

adoptNode, cloneNode, and importNode fail on this node type by raising a DOMException with the code NOT_SUPPORTED_ERR. importNode should also fail on XPathNamespace nodes.This was already fixed in the public draft.The Namespace node should be added to DOM Level 3 core and should be available via a read-only NamedNodeMap on element to reduce the confusion of adding a special node type for XPath.No change. There are no known problems with this add-on node type and uses beyond XPath are not anticipated.Node.namespaceValue should be identical to Node.namespaceURI and not null.No change.It is not clear why it should be this way since the infoset does not dictate it.

Method Detail

getOwnerElement

public Element getOwnerElement()
The Element 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.
