Interface XPathNamespace

All Superinterfaces:

Node

public interface XPathNamespace
extends Node

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.

See also the Document Object Model (DOM) Level 3 XPath Specification.

Since:

1.4, DOM Level 3

Modifier and Type	Method	Description
Node	appendChild(Node newChild)	Adds the node newChild to the end of the list of children of this node.
Node	cloneNode(boolean deep)	Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes.
short	compareDocumentPosition(Node other)	Compares the reference node, i.e. the node on which this method is being called, with a node, i.e. the one passed as a parameter, with regard to their position in the document and according to the document order.
NamedNodeMap	getAttributes()	A NamedNodeMap containing the attributes of this node (if it is an Element) or null otherwise.
String	getBaseURI()	The absolute base URI of this node or null if the implementation wasn't able to obtain an absolute URI.
NodeList	getChildNodes()	A NodeList that contains all children of this node.
Object	getFeature(String feature, String version)	This method returns a specialized object which implements the specialized APIs of the specified feature and version, as specified in .
Node	getFirstChild()	The first child of this node.
Node	getLastChild()	The last child of this node.
String	getLocalName()	Returns the local part of the qualified name of this node.
String	getNamespaceURI()	The namespace URI of this node, or null if it is unspecified (see ).
Node	getNextSibling()	The node immediately following this node.
String	getNodeName()	The name of this node, depending on its type; see the table above.
short	getNodeType()	A code representing the type of the underlying object, as defined above.
String	getNodeValue()	The value of this node, depending on its type; see the table above.
Document	getOwnerDocument()	The Document object associated with this node.
Node	getParentNode()	The parent of this node.
String	getPrefix()	The namespace prefix of this node, or null if it is unspecified.
Node	getPreviousSibling()	The node immediately preceding this node.
String	getTextContent()	This attribute returns the text content of this node and its descendants.
Object	getUserData(String key)	Retrieves the object associated to a key on a this node.
boolean	hasAttributes()	Returns whether this node (if it is an element) has any attributes.
boolean	hasChildNodes()	Returns whether this node has any children.
Node	insertBefore(Node newChild, Node refChild)	Inserts the node newChild before the existing child node refChild.
boolean	isDefaultNamespace(String namespaceURI)	This method checks if the specified namespaceURI is the default namespace or not.
boolean	isEqualNode(Node arg)	Tests whether two nodes are equal.
boolean	isSameNode(Node other)	Returns whether this node is the same node as the given one.
boolean	isSupported(String feature, String version)	Tests whether the DOM implementation implements a specific feature and that feature is supported by this node, as specified in .
String	lookupNamespaceURI(String prefix)	Look up the namespace URI associated to the given prefix, starting from this node.
String	lookupPrefix(String namespaceURI)	Look up the prefix associated to the given namespace URI, starting from this node.
void	normalize()	Puts all Text nodes in the full depth of the sub-tree underneath this Node, including attribute nodes, into a "normal" form where only structure (e.g., elements, comments, processing instructions, CDATA sections, and entity references) separates Text nodes, i.e., there are neither adjacent Text nodes nor empty Text nodes.
Node	removeChild(Node oldChild)	Removes the child node indicated by oldChild from the list of children, and returns it.
Node	replaceChild(Node newChild, Node oldChild)	Replaces the child node oldChild with newChild in the list of children, and returns the oldChild node.

Field Details

XPATH_NAMESPACE_NODE

static final short XPATH_NAMESPACE_NODE

The node is a Namespace.

Method Details

getOwnerElement

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.
