Finding&loading all possible id's?

Hi im not much of an action scripter or flash developer

And i dont really know the term i am looking for

Exanple

bla.php?id=0

What i am trying to do is load All possible Id’s of a url(in xml format) to a List

var Loader:URLRequest = new URLRequest("http://website.com/bla.php?id=");

i can load a single id by just doing

var Loader:URLRequest = new URLRequest("http://website.com/bla.php?id=14484");

But this isnt what i want to do

How would i got about requesting/finding all possible ids and then display said id’s or a certain part of each id to the list?

i dont really know how to explain it but i hope this helps and i hope some one can help

Thanks
