I've looked at this as well and have a project (sorry, can't give the source to this one) that does this kind of aggregation. The approach I took was to do that recursive, granular compostion you are referring to within the generator. I basically reached the conclusion that the process needed for that kind of composition wasn't really within the scope of what sitemap (cool as it is) was intended to handle.
I retunr to fully composed result as XML then and use the pipeline features to render it into the final display output. > ---------- > From: Christoph Henrici[SMTP:[EMAIL PROTECTED]] > Reply To: [EMAIL PROTECTED] > Sent: Wednesday, January 09, 2002 3:40 PM > To: [EMAIL PROTECTED]; [EMAIL PROTECTED] > Subject: Understanding cocoon ...... > > I have been studying, testing and playing around with cocoon in the > last few days as a newcomer : i am greatly impressed with what ease with > cocoon "pipelines" arbrary data sources can be "chained" to a result > target: a very powerful paradigm (pipe) applied in a powerful context > (http) by using great technology (xml, xlst).
