Loading SWF giving Instance name as TimeLine

Question

I'm Loading swf into a movieclip name main_mc. After
successfully loading it into main_mc. I had written a function to
get all children present in that movieclip(main_mc). It is getting
Children present in that, but every time it give [Object
MainTimeLine] as instance3 or sometime instance10. How can i
control instance name of maintimeline as it is randomly getting its
name.... I'm attaching code use in getting child and loading it...
Plz check if their any problem in code.
quote:
Clip=new Loader();
var urlRequest:URLRequest=new URLRequest("test.swf");
Clip.contentLoaderInfo.addEventListener(Event.COMPLETE,LoadingDone);
Clip.load(urlRequest);
private function LoadingDone(event:Event):void {
var _mc:MovieClip=event.target.content as MovieClip;
main_mc.addChildAt(_mc,0);
//if i trace the name of _mc movieclip... it will instance4
or instance10 randomly
trace(_mc.name);
showChildren(stage,0);
function showChildren(dispObj, indentLevel:Number):void {
for (var i:uint = 0; i < dispObj.numChildren; i++) {
var obj:DisplayObject = dispObj.getChildAt(i);
if (obj is DisplayObjectContainer) {
trace(padIndent(indentLevel), obj.name, obj);
showChildren(obj, indentLevel + 1);
} else {
trace(padIndent(indentLevel) + obj);
function padIndent(indents:int):String {
var indent:String = "";
for (var i:uint = 0; i < indents; i++) {
indent += " ";
return indent;
when loading is done suppose test.swf has one_mc movieclip
Children traced are like that...
quote:
main_mc [object MovieClip]
instance3 [object MainTimeline]
one_mc [object MovieClip]
[object Shape]
Can we solve this problem...

Answer 1

you can't control the instance name of a main timeline. but
if you name everything else, the main timeline will be the only
object whose instance name starts with "instance".
