You can use the URLLoader class to load XML data from a URL. To use the following code in
your applications, replace the
var myXML:XML = new XML();
var XML_URL:String = "http://www.example.com/Sample3.xml";
var myXMLURL:URLRequest = new URLRequest(XML_URL);
var myLoader:URLLoader = new URLLoader(myXMLURL);
myLoader.addEventListener("complete", xmlLoaded);
function xmlLoaded(evtObj:Event):void
