Class DOMStreamReader

java.lang.Object
  extended by com.sun.xml.ws.streaming.DOMStreamReader
All Implemented Interfaces:
NamespaceContext, javax.xml.stream.XMLStreamConstants, javax.xml.stream.XMLStreamReader

public final class DOMStreamReader
extends Object
implements javax.xml.stream.XMLStreamReader, NamespaceContext

Create an XMLStreamReader on top of a DOM tree.

Since various libraries as well as users often create "incorrect" DOM node, this class spends a lot of efforts making sure that broken DOM trees are nevertheless interpreted correctly.

For example, if a DOM level 1 tree is passed, each method will attempt to return the correct value by using Node.getNodeName().

Similarly, if DOM is missing explicit namespace declarations, this class attempts to emulate necessary declarations.
