title: Check if binding is soap protocol
body: <p>I want to check, what protocol a binding of a webservice uses. 
  For example:
  <a href="http://www.webservicex.com/globalweather.asmx?WSDL" rel="nofollow">http://www.webservicex.com/globalweather.asmx?WSDL</a></p>
  
  <p>Here we have 4 different bindings. I just want to get the soap binding on runtime.
  My groovy code so far:</p>
  
  <pre><code> Wsdl wsdl = Wsdl.parse(url)
   SoapBuilder builder = wsdl.binding().localPart(wsdl.getBindings().first().localPart).find()
  </code></pre>
  
  <p>How can I determine, which Protocol a binding uses?</p>
