@Allendar: I think your edit was quite contraproductive, as you changed the OPs input and output representation. — Bergi

var str = '(1)point 1 (2) point2 exception: some exception (3) point 3'
str = str.replace(/(\(\d+\)|exception\s*\:)/gi, "<br />$1");

The two directly nested matching groups look really unnecessary…

Actually, you could remove them fully and use $& in the replacement :-)

Thanks. new thing learnt, str.replace(/$\d+$|exception\:/gi, "<br />$&1"). Please tell me it's all better now :D

No, without the 1 - see MDN's docs

oops... str.replace(/$\d+$|exception\:/gi, "<br />$&") didn't notice the 1 in front of all replacements... thanks a lot. 2000 visits on your profile!
