[flexcoders] can't get XML working -- please help

[vetricom vetricom]

Hello,
I am trying to use XML object that I want to create and pass around and parse 
it at the receiving end and I can't get this simple code working. Any help is 
greatly appreciated.

Here is the code. It says "xmlVar.MyEvent.x" can't be resolved. I tried the 
lower case as well? but if I dump the xmlVar, it does display the xml tree 
correctly. I just can't seem to access the nodes.what is wrong with this code? 

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"; layout="absolute"
        creationComplete="initApp()">

        <mx:Script>
                <![CDATA[
                        
                        public function initApp():void {
                                trace("initApp");
                                var xmlVar:XML =
                                        <MyEvent>
                                                <x>10</x>
                                                <y>20</y>       
                                        </MyEvent>

                                trace(xmlVar.MyEvent.x);                
                        }
                ]]>
        </mx:Script>
        
</mx:Application>
