Loading external SWF?

1

i’m learning AS3.0 just 2 days. i create a XML menu in AS3.0 /with tutorial/.

my problem is loading external SWFs in AS 3.0, SWFs layered each other? i mean first one remove the previous one and load other one? and here is my code.


var xmlPath:String = "xml/mXML.xml";
var settingsXML:XML;

var loader = new URLLoader();
loader.load(new URLRequest(xmlPath));
loader.addEventListener(Event.COMPLETE, xmlLoaded);

function xmlLoaded(e:Event):void {
	if ((e.target as URLLoader) != null ) {
		settingsXML = new XML(loader.data);
		settingsXML.ignoreWhitespace = true;
		createMenu();
	}
}
function createMenu():void {
	var i:uint = 0;
	var dX:uint = 0;

	for each (var link:XML in settingsXML.links.link) {
		var mc:menuItem = new menuItem();
		mc.menuLabel.text = link.@nama;
		mc.swfLink = link.@link;
		mc.id = link.@id;

		mc.menuLabel.autoSize = TextFieldAutoSize.LEFT;

		mc.x = dX;
		dX = mc.x + mc.width + 10;

		mc.buttonMode = true;
		mc.mouseChildren = false;

		mc.addEventListener(MouseEvent.MOUSE_UP, mouseUpHandler);

		addChild(mc);
		i++;
	}
}

function mouseUpHandler(e:Event):void {
	loadSWF(e);
}

function loadSWF(targetSWF):void {
	var request:URLRequest = new URLRequest(targetSWF.target.swfLink);
	var loader:Loader = new Loader();

	loader.load(request);

	loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, contentLoading);
	loader.contentLoaderInfo.addEventListener(Event.COMPLETE, contentLoaded);

	function contentLoading(targetSWF:ProgressEvent):void {
		trace(" bytesLoaded: " + targetSWF.bytesLoaded + " bytesTotal: " + targetSWF.bytesTotal);
	}
	function contentLoaded(targetSWF:Event):void {
		addChild(loader);
	}
}
