A qouestion about procedure

1

I have this code for setting up my navigation. It works absolutely fine like it is, but I want to be able to change my arrays from OUTSIDE flash. Is it possible for me with this code to make it with XML or is it built in a way that makes that hard? I’m not an expert but think this is a good way for me to understand the whole deal with XML and arrays and such. What do you say, is it worth the while to try to implement XML and can someone just get me started on this? Thanks.
