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.

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.

Method Details
