XPathNamespace

Class Overview

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.

[Expand] Inherited Methods

From interface org.w3c.dom.Node abstract Node appendChild(Node newChild) Adds the node newChild to the end of the list of children of this node. abstract Node cloneNode(boolean deep) Returns a duplicate of this node, i.e., serves as a generic copy constructor for nodes. abstract short compareDocumentPosition(Node other) Compares the reference node, i.e. abstract NamedNodeMap getAttributes() A NamedNodeMap containing the attributes of this node (if it is an Element) or null otherwise. abstract String getBaseURI() The absolute base URI of this node or null if the implementation wasn't able to obtain an absolute URI. abstract NodeList getChildNodes() A NodeList that contains all children of this node. abstract 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 . abstract Node getFirstChild() The first child of this node. abstract Node getLastChild() The last child of this node. abstract String getLocalName() Returns the local part of the qualified name of this node. abstract String getNamespaceURI() The namespace URI of this node, or null if it is unspecified (see ). abstract Node getNextSibling() The node immediately following this node. abstract String getNodeName() The name of this node, depending on its type; see the table above. abstract short getNodeType() A code representing the type of the underlying object, as defined above. abstract String getNodeValue() The value of this node, depending on its type; see the table above. abstract Document getOwnerDocument() The Document object associated with this node. abstract Node getParentNode() The parent of this node. abstract String getPrefix() The namespace prefix of this node, or null if it is unspecified. abstract Node getPreviousSibling() The node immediately preceding this node. abstract String getTextContent() This attribute returns the text content of this node and its descendants. abstract Object getUserData(String key) Retrieves the object associated to a key on a this node. abstract boolean hasAttributes() Returns whether this node (if it is an element) has any attributes. abstract boolean hasChildNodes() Returns whether this node has any children. abstract Node insertBefore(Node newChild, Node refChild) Inserts the node newChild before the existing child node refChild. abstract boolean isDefaultNamespace(String namespaceURI) This method checks if the specified namespaceURI is the default namespace or not. abstract boolean isEqualNode(Node arg) Tests whether two nodes are equal. abstract boolean isSameNode(Node other) Returns whether this node is the same node as the given one. abstract 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 . abstract String lookupNamespaceURI(String prefix) Look up the namespace URI associated to the given prefix, starting from this node. abstract String lookupPrefix(String namespaceURI) Look up the prefix associated to the given namespace URI, starting from this node. abstract 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. abstract Node removeChild(Node oldChild) Removes the child node indicated by oldChild from the list of children, and returns it. abstract Node replaceChild(Node newChild, Node oldChild) Replaces the child node oldChild with newChild in the list of children, and returns the oldChild node. abstract void setNodeValue(String nodeValue) The value of this node, depending on its type; see the table above. abstract void setPrefix(String prefix) The namespace prefix of this node, or null if it is unspecified. abstract void setTextContent(String textContent) This attribute returns the text content of this node and its descendants. abstract Object setUserData(String key, Object data, UserDataHandler handler) Associate an object to a key on this node.
