 Seems pretty straight forward but i haven't found a (good) solution
 yet. 

Check out look-around (-behind, -ahead), here for instance:

http://www.regular-expressions.info/refadv.html

 Surprisingly i couldn't figure out how to say '/!(not) this/'. Seems

!/this/

 Hi all,

 I consider myself quite good with Regular Expression, but i could never find
 out how to match something like:

 match this but not this and that

 so i would like to match the first match this (or another this) but not
 not this.

 Seems pretty straight forward but i haven't found a (good) solution yet.
 Please no solutions with extra code, i know how to do that. I need a regular
 expression that can do it, preferably Perl compatible. Surprisingly i
 couldn't figure out how to say '/!(not) this/'. Seems like there must be a
 simple way, but i can't seem to figure it out.

 Tried things like: '/[^n][^o][^t] this/', '/[^not]{3} this/' etc but all of
 those don't work. Looked in various books and websites but didn't find what
 i was looking for...



try this

/match this but (?!not this and that)/

goodluck!

Please enlighten me if you can.
