This may be overkill for your purposes, but you may want to look at a
pipelining solutions such as Cocoon (or similar).  With such tools, an
input configuration XML can drive one XSLT which then in turn goes off
and grabs the appropriate data and/or runs the appropriate XSLT to do
the actual work.

In our case, we're completely meta data driven and as such we use
Cocoon to do things like building dynamic XSLT (ie, using another
configured XSLT) which are then used to transform other XML (or
validate responses via Schematron in our case).

In your case, simply placing the SITE/MODULE/VIEW definitions in
appropriate directories and subdirectories and using successive XSLT
to grab each in turn based on directory path parameters built in, or
passed from, the previous transform should work without all the Cocoon
machinery if the specific transforms are static and only the input
