@XSGeek - been too long since I got a chance to play with regex.
It's like putting on an old favorite t-shirt.
@XSGeek - and you may need to remove the opening bracket - (copy and paste)
@XSGeek - and if it's in N++ - remove the opening and trailing slashes.
@XSGeek - so... to be clear: try this one
13(:\d\d){2}\s+(INF|DBG)
(removing surrounders, and making an assumption that there may be more than 1 space between TS and tag)
