Need a scrip to help fill complex XML

We've developed a game and need an easier way to input new equations.
www.kategeronimo.com/newPortfolio/FebUpdates/QE/QEPreloader4.html

Thus, we are looking for quick script that will output an XML file, to allow non-IT trained person to create more variations on our questions. The sample XML structure is below.

Please PM with your suggestion and price.


Thanks
