public final class DOM2Helper
extends java.lang.Object

This class provides a DOM level 2 "helper", which provides services currently not provided be the DOM standard. This class is a copy of the one in org.apache.xml.utils. It exists to cut the serializers dependancy on that package. The differences from the original class are: it doesn't extend DOMHelper, not depricated, dropped method isNodeAfter(Node node1, Node node2) dropped method parse(InputSource) dropped method supportSAX() dropped method setDocument(doc) dropped method checkNode(Node) dropped method getDocument() dropped method getElementByID(String id, Document doc) dropped method getParentOfNode(Node node) dropped field Document m_doc; made class non-public This class is not a public API, it is only public because it is used in org.apache.xml.serializer.

Method Detail

getLocalNameOfNode

public java.lang.String getLocalNameOfNode(org.w3c.dom.Node n)

Returns the local name of the given node, as defined by the XML Namespaces specification. This is prepared to handle documents built using DOM Level 1 methods by falling back upon explicitly parsing the node name.

Parameters:

n - Node to be examined

Returns:

String containing the local name, or null if the node was not assigned a Namespace.

getLocalNameOfNodeFallback

private java.lang.String getLocalNameOfNodeFallback(org.w3c.dom.Node n)

Returns the local name of the given node. If the node's name begins with a namespace prefix, this is the part after the colon; otherwise it's the full node name. This method is copied from org.apache.xml.utils.DOMHelper

Parameters:

n - the node to be examined.

Returns:

String containing the Local Name

getNamespaceOfNode

public java.lang.String getNamespaceOfNode(org.w3c.dom.Node n)

Returns the Namespace Name (Namespace URI) for the given node. In a Level 2 DOM, you can ask the node itself. Note, however, that doing so conflicts with our decision in getLocalNameOfNode not to trust the that the DOM was indeed created using the Level 2 methods. If Level 1 methods were used, these two functions will disagree with each other.

TODO: Reconcile with getLocalNameOfNode.

Parameters:

n - Node to be examined

Returns:

String containing the Namespace URI bound to this DOM node at the time the Node was created.
