WebService response object in XML - parsing attributes

Question

Hi- new to Flex and I'm trying to parse out the attributes of the response object. I can get the entire object and see that its working, but I cant get just a single attribute. It pulls weather info for world cities. For example, I just want the location name and temperature.
Any advice on this? Thanks!

Answer 1

The WSDL says GetWeatherResponse is a string, and it appears to be a string of XML, so set <mx:operation resultFormat="object"> as this will unwrap the SOAP response value and leave a string typed value intact. You can then create a new ActionScript 3.0 E4X-based XML instance from the unwrapped string:
    var myXML:XML = new XML(event.result.toString());
You can then travese the XML document using E4X syntax, a simple example is included below:
    trace(myXML..Location);
    trace(myXML..Temperature);
