A scan through the soap4r code finds no matches on WSDL. I'm wondering if a
method  could be added to driver.rb for reading a WSDL source (local file,
http, ftp,  whatever). The driver would parse each WSDL method definition,
calling addMethodWithSOAPAction as it goes.

Of course, the devil is in the details:  What XML parser to use, how good
is the namespace support, how tedious is WSDL-method extraction, handling
of the WSDL 'import' element, and so.

But if the same information you pass to addMethodWithSOAPAction is in a
WSDL file, then it's certainly doable.
