Parsing entries in a log file

Scripting Forums AppleScript | Mac OS X
#1

Hey Forum.

I need some help figuring this out. In my AppleScript application, I’ve integrated a logging component to log of all the files it has processed. The information written to a .txt file and each line contains a timestamp followed by a ‘tab’ and the file name. When the application begins working on a new batch of files, there’s an entry indicating a new batch has started. A sample log file follows below:

After the batch of files runs, I want to read the log and only pull the entries for the latest batch, then include that in an e-mail.
I’ve got to the point where I can read the log file and pull the entire contents of it into an AppleScript var as a list. The e-mail component is all set up and waiting to plug in a variable that contains the parsed list.

An example of how the entries from the last batch of the log should look – omitting the “Processing Start for Batch” message.

But I’m stuck on how to parse the list for just the last entries for last batch of files processed.

Any advise would be appreciated.

Thanks,
-Andrew
