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
.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.
