title: How to refer to Object attribute without knowing exact name?
body: <p>I'm actually working with SOAP at the moment, and annoyingly the response name varies depending on the method I call.  For example, one method will respond with..</p>
  
  <p>$response->SendOrderResult</p>
  
  <p>whilst another responds with </p>
  
  <p>$response->GetOrdersStateResult</p>
  
  <p>Is there a way of referring to the value without knowing the name?  ie something like $response->*Result</p>
