Class DocumentHandlerProxy

java.lang.Object

com.icl.saxon.output.Emitter

com.icl.saxon.output.DocumentHandlerProxy

All Implemented Interfaces:

javax.xml.transform.Result

public class DocumentHandlerProxy
extends Emitter

A DocumentHandlerProxy is an Emitter that filters data before passing it to an underlying SAX DocumentHandler. Note that in general the output passed to an Emitter corresponds to an External General Parsed Entity. A SAX DocumentHandler only expects to deal with well-formed XML documents, so we only pass it the contents of the first element encountered.
