what would be regex for below pattern?

Question

<msg info=access_denied>  

Access_denied can be anything "permit" "Thrashing"

I tried using regex

m/<msg info=([^]*)>/i

It is giving unmatched regex.

What should be actual and correct regex ?

Answer 1

Your negated character class is missing the > character, for anything not >:

m/<msg info=([^>]*)>/i

However, just note that if your data is XML, you should consider using an actual XML Parser to pull that data.

Answer 2

I think you are looking for

/<msg info=([^>]+)/

Assuming the input is as you described (no quotes, etc).
