Here's one:

Another approach that might be worth investigating is to load the
RDF/XML into one of the many RDF APIs, run a SPARQL SELECT query
against it, then apply XSLT to the results. Though there's an obvious
increase in the system complexity, it might well make managing the
stuff easier - the query could translate the RDF into a structure
broadly like Prolog, then the XSLT finish up the syntax details.

Note too that there are RDF/XML tools available for Prolog, probably a
parser available. Funnily enough a quick google yielded this old
xml.com article from Bijan Parsia, in which he compares DCGs to XSLT
in ther context of RDF with Prolog:
