In Java, I currently use a special reader that adds an additional root
element to the stream (see below). My life would become much easier if I
could tell the parser that it is reading a fragment (without root
element) only...

Vector streams = new Vector ();

streams.add (new ByteArrayInputStream ("<root>".getBytes ()));
streams.add (new FileInputStream (new File (path, "changes.log")));
streams.add (new ByteArrayInputStream ("</root>".getBytes ()));
parser.parse (new InputSource
              (new SequenceInputStream (streams.elements ())));

I have another fragment-related problem:

Imagine I have an xml parser for a particular type of content. Now, I
want to send this type of content, and for sending it is included in a
kind of "xml envelope". 


Currently, the envelope handler delegates all content related events to
the content handler.  

It would be much nicer if I could switch the DocumentHandler by calling
"setDocumentHandler", and the documentHandler would switch back
automatically when back at the corresponding nesting level.  However,
the suggested semantics requires maintenance of a stack of
DocumentHandlers in the parser.

Best regards
