Parse SOAP over HTTP - which library ?

I have a need simply to handle/parse some SOAP messages
over HTTP protocol in a larger C++ program.  Specifically,
I need to strip off HTTP and SOAP protocol, and extract the
inside XML data for further processing.  I don`t need it to do
anything with the web service methods.

    Which C++ library would you recommend for doing this very quickly
(e.g., gSOAP, Simple SOAP, etc.) ?
Is there an example that would jump start this effort?

                              Thanks, Alan
