ok, this is a doublepost from the "for beginners" .. I was suggested to try here ...
this is what puzzels me for now.
I am going to create an xml document with a dtd. and this is what I have to record.
Olympic Atlanta 1996
Results sprint 100m
person: Donovan Bailey (Canada) time: 09.84
person: Michael March (USA) time: 10.00
results sprint 200m
....
Next olympic...
What I see here is that I can create one record of persons (name, country ++ ), and one record (game, type, results ). But wether I make an xml doc based on (game, type) and record athletes and their results .... or based on (name, country ++ ) and record game, type, results.

if there is a better way to avoid re-typing the same info over and over again, tell me about it. Now I have to choose to retype each athletes, or each game ...
