Here is what i suggest, it is a two step solurion
ther regex is
^user:\x20([^\r\n]+)\r\ndate:\x20([^\r\n]+)\r\ntime:\x20([^\r\n]+)\r\n
((Player:\x20([^\r\n]+)\r\n)*)
sorry if the above gets broken into multiple lines :) it is not me!
apply it and collect $1,$2,$3,$4 variables
and here comes the 2nd step: delete all occurencies of "player: " and
line breaks as well from the 4th variable
And you are ready!
