DOM2Helper

public final class DOM2Helper extends 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 com.sun.org.apache.xml.internal.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 com.sun.org.apache.xml.internal.serializer.

public DOM2Helper()
Construct an instance.

Methods Summary
public java.lang.StringgetLocalNameOfNode(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.
param
n Node to be examined
return
String containing the local name, or null if the node
was not assigned a Namespace.

    String name = n.getLocalName();

    return (null == name) ? getLocalNameOfNodeFallback(n) : name;
  
private java.lang.StringgetLocalNameOfNodeFallback(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 com.sun.org.apache.xml.internal.utils.DOMHelper
param
n the node to be examined.
return
String containing the Local Name

    String qname = n.getNodeName();
    int index = qname.indexOf(':");

    return (index < 0) ? qname : qname.substring(index + 1);
  
public java.lang.StringgetNamespaceOfNode(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.
param
n Node to be examined
return
String containing the Namespace URI bound to this DOM node
at the time the Node was created.
    return n.getNamespaceURI();
