Extracting arrays from http.reponseText

I am completely new to this so please bear with me here. My project involves a webpage executing php scripts via an xmlhttprequest which queries a database and returns data to the webpage. This code below is working to a degree in IE7. As I have not yet parsed http.responseText, I am getting all the code in parts.php in the alert. My php script query creates two php arrays, one a single array and a two-dimensional array such as array[][]. My first question is how can I extract these arrays from http.responseText so I can display them. My 2nd is, stepping through the code in tomcat v5.0.28, the script executes the first alert showing http.readyState = 1, but then stops/fails even with the firewall disabled. Looking at the code below, can anyone suggest a possible reason why? Any help appreciated.
