Thanks, Matthew! (and everyone).

This Ruby 5-liner (example) is exactly what I wanted:

require 'soap/wsdlDriver'
wsdl_url = 'http://www.weather.gov/forecasts/xml/DWMLgen/wsdl/ndfdXML.wsdl'
proxy = SOAP::WSDLDriverFactory.new(wsdl_url).create_rpc_driver
obj = proxy.LatLonListCityNames("1234")
print obj

Followup questions:

 % What's the best mailing list for SOAP/etc newbies?

 % http://www.programmableweb.com/apis lists many services that use
 REST + other non-SOAP protocols? I assume similar Ruby
 classes/modules exist for those?

 % Is there a Ruby "metaclass" that recognizes whether something is
 SOAP/REST/etc, and adapts accordingly?

 % It seems "easy" to create a dynamic GUI for SOAP for a given
 endpoint. First, a pulldown list of all methods available from an
 endpoint. When you choose a method, you'd get fields for the
 arguments, matching the argument type (eg, pulldown for list,
 etc). Has anyone done this? Couldn't use static HTML (since the
 arguments depend on the method), but DHTML might work (though I'd
 prefer standalone Java or something).

 % One ugliness w/ the code above. "obj" is just an ugly XML string
 (which is what the API promises, so I can't complain too
 much). However, this string is really in "DWML" format described at:

http://www.weather.gov/forecasts/xml/DWMLgen/schema/DWML.xsd

How do I really ruby "parse this string per the URL above + return an
object"?

 % I want to try SOAP stuff myself, with a twist. Let's say I want to
 return something that includes a city as part of the return
 value. Instead of returning the city name/etc, I want to return a
 geonames id and tell the client "fetch more info for the city from
 geonames". Can I do that? Is that a "mash up"?
