public class EmbeddedXMLPipe
extends AbstractXMLPipe

This class implements a ContentHandler for embedding a full SAX event stream into an existing stream of SAX events. An instance of this class will pass unmodified all the SAX events to the linked ContentHandler, but it will ignore the startDocument/endDocument and startDTD/endDTD events, as well as all comment events within the DTD.
