Yes, that's how SOAP works. The WSDL document is an interface definition -
it tells SOAP clients what methods are there to call, how to call them, etc.
The SOAP client is responsible for building a SOAP envelope containing the
appropriate method call, and the SOAP server is responsible for building a
SOAP envelope containing the response of that method call.
Some SOAP services do return XML documents within their SOAP envelopes
(which are themselves XML documents, of course). But you'll always have to
call one of the services described by the WSDL file.
You can certainly use XPath expressions with the contents of the SOAP
envelope you get back, although this is usually not a good idea unless the
SOAP server returns an XML document as its response ("document/literal" vs
RPC-encoded SOAP services).

XPath provides the name() function which can be used to find nodes without
using the namespace prefix; I don't know if the specific classes in question
support that, though.
