[FEEDBACK] Is this script efficient...is there a better way?

[Bob X]

Just a quick test at home. On a 690K file the results were:

RE based script: 0.11
Original script: 0.12

I ran it a couple times and they were always with 1 or 2 ticks of each 
other but the RE one was always the faster.

I will try the same at work with the 30MB files to see if that makes a 
difference as well.
