fix the attached sample code in main class file

loadXML() method uses 2 arguments only – loadXML($url:Array, $names:Array)

You’ve mixed it up with class constructor arguments –
XMLLoader([$url:Array, $cache:Boolean, $names:Array, $skipErrors:Boolean])

var xl:XMLLoader;
var array:Array;
xl = new XMLLoader();
array = new Array();
xl.addEventListener(Event.COMPLETE, loaded);
xl.addEventListener(ProgressEvent.PROGRESS, loading);

xl.loadXML(["http://flashden.net/feeds/user_item_comments/cg219.atom", "http://feeds2.feedburner.com/kreativeking?format=xml"], ["xml1", "xml2"], false);

function loaded(e:Event):void {
trace(e.target.data["xml1"]);
}

function loading(e:ProgressEvent):void {
trace(e.target.ratioLoaded);
}

I get this error:
xl.loadXML(["http://flashden.net/feeds/user_item_comments/cg219.atom", "http://feeds2.feedburner.com/kreativeking?format=xml"], ["xml1", "xml2"], false);
1137: Incorrect number of arguments. Expected no more than 2.

Is there something I am doing wrong. please let me know.

Thanx
