I feel certain that this sort of question will have been asked before, but I just can't find it! So sorry about that...

I have a couple of substitutions that replace e.g. \n with line-break tags and \t with several non-breaking spaces. However I would like to make the regexs not match for anything enclosed in pre tags tags.

e.g. currently
$$body=~s{\n}{<br/>}gis;
e.g. I would like:
$$body=~s{(!PRECEDED BY SOMETHING.*)\n(!FOLLOWED BY .*SOMETHING}{<br/>}gis;

I guess a lookahead would handle the first condition (i.e. don't match if preceded by a pre tag and/or a bunch of arbitrary other-characters, but that won't work with a lookbehind, because they can't be an arbitrary length right? So I'm a little stuck...

Cheers,
JJ
