ActionScript How to access child Sprites - actionscript-3

Question

I have the following problem. Would appreciate if someone takes the pains to answer it.
Problem Description: I have a top level Sprite "TopLevel",
there is a Sprite under it "allRoutes",
there is child Sprite under it "Routes" and
there is another child under it "Route".
I want to access each level in a loop. I have tried doing it in ActionScript but not with success.
Here is the probable code (it is not compiled successfully):
package
{
import flash.display.Sprite;
public class TopLevel extends Sprite {
public function TopLevel() {
var allRoutes:Sprite = new Sprite();
for (i = 0; i < 3; i++) {
var routes:Sprite = new Sprite();
for (j = 0; j < 4; j++) {
var route:Sprite = new Sprite();
route.name = "Route:" + i + ", " j;
routes.addChild(route);
}
routes.name = "Routes:" + i;
allRoutes.name = "AllRoutes";
allRoutes.addChild(routes);
}
addChild(allRoutes);
trace (allRoutes.name);
for (i = 0; i < allRoutes.numChildren; i++) {
trace(allRoutes.getChildAt(i).name);
for (j = 0; j < allRoutes.getChildAt(i).numChildren; j++) {
trace(allRoutes.getChildAt(i).getChildAt(j).name);
}
}
}
}
}
I am expecting the following result:
AllRoutes
Routes-1
Route-1, 1
Route-1, 2
Route-1, 3
Route-1, 4
Routes-2
Route-2, 1
Route-2, 2
Route-2, 3
Route-2, 4
so on..
Hope you get the picture.
Thank you very much in advance.
thanks and regards

Globally your code is fine, except some little things :
You forgot to declare i and j variables :
var i:int, j:int;
You forgot the concatenation operator before j in this line :
route.name = "Route:" + i + ", " + j;
If your are compiling with the strict mode, these instructions will fire errors :
allRoutes.getChildAt(i).numChildren
and
allRoutes.getChildAt(i).getChildAt(j).name
which can be in that case :
for (j = 0; j < Sprite(allRoutes.getChildAt(i)).numChildren; j++)
{
trace(Sprite(allRoutes.getChildAt(i)).getChildAt(j).name);
}
...
And as your for loops are starting by 0, you will get something like this :
AllRoutes
Routes:0
Route:0, 0
Route:0, 1
Route:0, 2
Route:0, 3
Routes:1
Route:1, 0
Route:1, 1
...
Hope that can help.
