- 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.
