Dear Monks,

I have a daily log file with tens of millions of records like: 
======================================================================
Record: 9868943   Version:  2   Timestamp: Sat Feb 18 22:33:43 2006
Primary (Reporting) ID: 240  Level: 2 Group: 1  Reg: no  Event:  51748
Keep: 1  ID-Node: 0x2017  Inverse: 25
Secondary ID:
Keep: 1   ID:  68   Inverse: 23   
Keep: 1   ID: 240   Inverse: 27   
Keep: 1   ID: 368   Inverse: 30   
======================================================================
Record: 9868944   Version:  2   Timestamp: Sat Feb 18 22:33:44 2006
Primary (Reporting) ID: 67  Level: 9 Group: 0  Reg: no  Event:  51749
Keep: 1  ID-Node: 0xA087  Inverse: 55
Secondary ID:
Keep: 1   ID:  62   Inverse: 73

I need to get the "Primary (Reporting) ID", "Level", "Group", "ID-Node", and "Inverse" values. I also need to get n-to-4 of the "Secondary ID" fields stripped out of each record which I will then insert into a DB.

I thought about using a regexp to replace all spaces with a comma and the "===" lines with a "\n" and write it to a temp file.

Then I'd iterate line by line over the temp file splitting the CSV string into an array and then get my data elements like that. Similar to what I saw at Parsing multi-line records

Does that sound like a good start or should I be trying another method?
