That sounds like FCP 3.x. If you have it installed or installable, load the project and see if you can export the XML for it. If it's available that early, use the highest version number possible.
I believe such files will parse into FCPX with help from the utility
SEND TO X (formerly 7 To X) from Intelligent Assistance, which brings home the bacon for 10 bucks.
Not sure if XML export is even available in FCE; it was a pretty stripped down version.
HTH
Best, as always.
