ActionScript 2.0 :: Convert SETTINGS To XML And Update?

I have a SETTINGS.as file that looks like the following:

Code:

function SETTINGS()
{
this.version = "1.00.01 Build QA-01"

My project is to read this class into an XML file. The values in this SETTINGS file can change at any time. I guess my first question is how to do that, how do you read an ActionScript 2.0 class into an XML file? My 2nd problem is how do you take the XML file and update it in the SETTINGS file via XML?? Like say the serverName changes from STARK to WAYNE, how do you change this in XML?
