[flexcoders] Help sifting through XML (from HTTPService) with a foreach loop [new to Flex]

[Alex]

I have an XML file that looks like this:


<a>
 <b>
   <c>
     <data>1</data>
   </c>
   <c>
     <data>2</data>
   </c>
 </b>
</a>


I'm fetching it with..


        <mx:HTTPService 
            id="ticketDataRequest" 
            url= "{FLEXsys.proxy}"
            useProxy="false" 
            method="POST" 
            resultFormat="object"
            showBusyCursor="true"
            result="ticketDataRequestHandler( ticketDataRequest.lastResult )">
            <mx:request xmlns="">
                <action>ticketData</action>
                <id>{ticketID}</id>
            </mx:request>
        </mx:HTTPService>


In my ticketDataRequestHandler, as exercise, I just want to 'alert'
what's in the data blocks... I've tried:

private function ticketDataRequestHandler(data:Object):void {
    for each (var d:Object in data.a.b..c){
        Alert.show( d.data);            
    }
}

and every permutation thereof - and it just won't work for me..

Help appreciated!
