Hi All,

I need to create log files (data) mining tool.
Are there any Python classes/modules/functions that are usually used in these cases, apart from "playing" with regular expressions ?

The logs comprise of lines like so:

Jul 31 09:53:13 iSW-00-091 kernel: T3=0x3a52b1e:3:0x8:fcs:FcsGetVpdListCompletion[669] FCS Get VPD List: lport 3,  rport 10c00,  LunIdx 1 Unknown Cmpl [ 0 0 88 ]

And I need to be able to zero in on lines like:

Jul 31 09:56:13 ssp8400 kernel: Dump for [IB_FCP SEST]  xxx=0x1592
And then go forward/backwards in the log and get data related to the error message.

Thanks,
Ron.
