Re: How to incrementally add to a result document?

Roger,

Yes, what Martin said.

If you don't like separate modes because you want your tracing logic
coupled closely to your transformation logic, the classic 'XSLT approach'
would be to build a unified tree in one pass, then post-process that tree
twice, once for main outputs (filtering out the logs) and a separate time
for the trace log (filtering everything else).

Indeed you might find with the second pass to extract the trace log, you
can also enhance it usefully.

More generally, to make XSLT work you need to adopt a 'pipelining'
mentality, by which I mean an idea of separate discrete steps achieving
discrete aims, working in combination - for example in this case,
generating the logged information is actually separate from writing it to a
file.

Good luck, Wendell
