All Implemented Interfaces:
Constants, ContentHandler, LexicalHandler, StxEmitter

public class DOMEmitter
extends StxEmitterBase

This class implements the common interface StxEmitter. Is is designed for using DOMResult. So it generates a DOM-tree, which can be exported with the method getDOMTree().
