Playtesting data & xml

I'm in the playtesting phase of my game in AS3, and I know I would benefit greatly from being able to track statistics like average player deaths, time to finish levels, and common locations where players die. It seemed like maybe xml was the best way to track this information, but I looked into it and frankly I'm completely lost. I don't need to worry about people hacking the data or more than ~50 users, and any tutorial I've been able to find on the subject goes into WAY too much complex detail that keep derailing me.

Can anyone give me a simple example I could use or point me in the right direction?
Thanks
