Transforming the whole soap response

In a test web service client I've written recently I transform the
SOAP response XML using XSLT.  I'm not extracting the soap body, I'm
transforming the whole lot.

The XML returned in the response is reasonably complex, and the target
is HTML so it seems natural to use XSLT.  Not being familiar with SOAP
I'm just looking for confirmation that this is ok.  Has anyone written
a system where the entire response is transformed, is there anything
to look out for?

cheers
