ActionScript 3.0 :: XML String Into Different Pages

I have some flash code and an XML file that creates dynamic buttons that allow you to cycle through the XML file. Im trying to integrate this code into my .FLA but I want to get rid of the code that tells it to rely on the dynamic buttons, and instead, use my non-dynamic navigation I already have built to load the specific part of the XML depending on which page you click in my nav.

I just don't know what to strip - and what to add to the code to make it work.

My .FLA is setup in that each "page" is on a different layer on frame 1, so it uses actionscript to fade in and out of each "page".

Heres a link to the working example of the XML I found: [URL]

Heres my actual site to give you a better idea of what i want to integrate in: [URL]

Heres the XML code, file called products.xml:

Code:
<?xml version="1.0" encoding="UTF-8"?>
<products>
<product id="42">
