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... Please enlighten me if you can.
