Reg Expression query

[UKSTU]

Hi

I'm trying to ignore a number sequence when compelting a text compare. (See attached jpg). I believe i have the reg expression detailed correctly, but for some reason Beyond Compare is not ignoring the difference as i would expect.

Could you advise if I am not detailing the rule correctly.

I'm tring to detail a rule to ignore;

Extract 1 001496906564311618588
Extract 2 001531417563311618588

001/d{18}


The numbers will continue to change throughout the file, so i was basing the exception on the three digits at the start of the string 001.

Many thanks,
Stu

Hello,

That's very close. You just need to use \ instead of /.
001\d{18}

Then in the Session Settings, Importance tab, make sure that "Exclude CUNI Number" is unchecked. Then optionally change "Use for this view only" to "Also update session defaults" to apply for future comparisons.
