Question

ie.

a b i u ol ul li

tag does not match but

br

and any other tag matches.

Thanks in advance.

The regex i got atm is

/<([a-zA-Z]{2,})\b[^>]*>/g

which does not satisfy not matching ul and ol

Answer 1

This is probably what you want (it will only match open tag, by the way, since I mimic what you have):

/<\s*(?![uo]l\b)([a-zA-Z]{2,})\s*>/g

I allow optional space after < and before >.

I use negative look ahead (?![uo]l\b) to check the tag is not either ul or ol. I throw in a word boundary check \b to make sure it is not part of some user-defined tag.

I assume the tag name contains only English alphabet. You can modify the regex if this assumption does not hold.
