WSDL imported, but no operations shown under the interfaces

I need to get the valid XML requests for the operations that are available in te WSDL (since the party providing the webservice does not want to help, probably does not even know how), but SoapUI does not show them, even though every tutorial/documentation/whatever shows that it should.

I import the WSDL, I get two interfaces, but nothing under those.

If I open the interface viewer, then still, if I find the correct operation (under WSDL Content), there is no way to get any XML I can use as the request.

How do I get the exact XML I need to use as a request for one such operation described in the WSDL?
