Parse Data from a log

[KrazyFire]

I have a big Log from a game server and i want to get some Data like on the lines with AdminMsg: on them as it says players name and IP Address where i would put this class in my admin control panel which im making. I built only that start where it opens the log file which does at the start with no errors but i dont know much how i can these all the AdminMsg: .. here is a snipet of a chatlog

[7/12/2010 15:42:34]: AdminMsg: [b]|Ro!!a[\b] connected (93.141.2.195).

What have you tried so far, its all good and all giving us a chat log but its a little pointless in us just giving code out that will solve the issue.
