Yep. If you've got any control over the original XML then it might be
worth considering making it "coincidentally" RDF/XML, see:
http://www.xml.com/lpt/a/2002/10/30/rdf-friendly.html

Yep. The n3/cwm tutorial is pretty good on this:
http://www.w3.org/2000/10/swap/doc/
You may be able to do the logic using *standard* RDFS/OWL inference -
cwm, Euler, Jena, Pellet, one of the DL reasoners.

Depending on what you're trying to do SPARQL may be an option here
too, using CONSTRUCT.
A twisty possibility might also be to follow the route -

[RDF] SPARQL -> xml results -> xslt/xquery -> RDF/XML

I'm only guessing, but I think this would probably be straightforward
for simple transformations/mappings but would probably get hard to
control for anything beyond those.

Yep. This works wonders ;-)
