How do I use an an XSLT stylesheet to transform info being received from 3rd party WS

[lahatfield]

I am connecting to a 3rd party web service which has function built in such as CreateIndividual, UpdateIndividual, SearchforIndividual. When calling any function on the web service I have an overide on the ProcessMessage void of the SoapExtension so that I can include my security token. This all works great except that when I search for an individual and return the object to my code it fails saying there is an error in the XML, obviously the first people I went to were the people who wrote the service but they cannot make any changes to it so have suggested I use XSLT to transform the xml into a simpler format, which they have provided.

That is all great but HOW do I actually slot it in as I am calling "Built in" functions of their webservice to do what I need to do.....would i need to build up my own Soap Message and parse that to the webservice so that I am getting the soap message straight back to my app. instead of through their objects?

I really hope that made sense...it made sense in my head.....
