Question

I’m having an issue with my regex matching a string which I do not want it to match. I can’t seem to find the correct syntax for the expression. Here is an example:

String:

ABC098765432109,~~Z 10Y-123~This is a test^ABC-DE-_F

Regex:

m/^.\*?,\d\*[\~]{2}\w\s\d\*\w-\d\*~.\*?\^.\*?-.\*?-.\*?_\w$/

---

The ,\d* portion I thought would eliminate the string which has no digits directly after the comma.

Any suggestions on getting this to work?

Answer 1

"*" means “zero or more”. You may want "+", which means “one or more”. So,

m/^.*?,\d+[\~]{2}\w\s\d*\w-\d*~.*?\^.*?-.*?-.*?_\w$/

does not match

",~~Z 10Y-123~This is a test^ABC-DE-_F"
