ActionScript 2.0 :: Load Data From Mysql To Xml To Flash Using Php?

I am trying to load data from mysql to xml to flash using actionscript and php. Im doing something wrong but not sure what.Basically, my php file (latestnews.php) looks like this

Code:
<?php

header("Content-type: text/xml");

$host = "host";
$user = "user";
$pass = "password";[code].......

this is placed in the same frame number as the dynamic text fields but on a seperate layer. The dynamic text fields are:

Title_txt
Comments_txt
Date_txt

There is no output error but nothing is showing up. The file is using actionscript 2.0 and wondering if the actionscript i am using is write for that format?
