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 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.
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.
