SOAP is a bit of a PITA.

But here is what I did a little while back using luasoap-1.0b:

> require "soap.http"
> ns, meth, ent = soap.http.call("http://api.google.com/search/beta2";, "urn:GoogleSearch", "doGoogleSearch",

attr    table: 0045A4C8

Essentially, the result of the SOAP request is a LOM tree, that you'll
have to decode yourself.  Not hard, just tedious.

Anyone out there working on a WSDL to Lua stub generator?
