Demo of node.js SOAP client

index.js

var soap = require("soap");

soap.createClient("http://www.w3schools.com/webservices/tempconvert.asmx?WSDL", function(err, client) {
  if(err) {
    console.error("Can't create client", err);
    return;
  }
  client.CelsiusToFahrenheit({Celsius: "25"}, function(err, result) {
    if(err) {
      console.error("Can't call method", err);
      return;
    }
    
    console.log(result);
  });
});

I get a really nice error stack while parsing my wsdl:

/Users/couto/Development/[redacted]/node_modules/soap/lib/wsdl.js:784
      var base = typeElement.description(definitions, xmlns);
                             ^
TypeError: Cannot call method 'description' of undefined

On the other hand I can parse the same wsdl with soap-attrib, but it then fails to construct the correct request.

I'm currently diffing the two to see if I can fix this, but I'm quite open to ideas since I'm not a SOAP expert, in fact it's my first big adventure with soap services.
