I think Stefano is on the right track with this dynamic PI pattern ... but
since I never used C1 I've only got a theoretical notion of the C1
"reactor". But I've used a similar pattern in C2, I think. You can use a
pipeline (or a small number of pipelines) containing an XSLT transformer
followed by an include transformer. The XSLT transform can make your
decision, and insert elements like this:
<xi:include href="cocoon://{$result-of-some-complex-functional-logic}"/>
Then the include transformer resolves the url and recursively calls the
sitemap. The URL could resolve to a database query result, or an error 500
page. This gives you quite a functional "style" where you need it. One issue
I'm aware of here is the "cacheability" of the include transformer, but this
may not be an issue which your search results anyway.
