Hi Monks !
I'm having trouble building a regex that would match as follows:
string starts with
chars, contains
this, but does not contain
that and does not end with
whatever
A couple of samples:
- chars at the beginning, this is right and whatever is not at the end
- chars at the beginning, this is ok and the end is whatever
- chars at the beginning, this is ok and that is included
- chars at the beginning, that here this is not ok
This regex will match 1 and 2, and correctly skip 3 and 4:
^chars(?!.*that).*this(?!.*that).*
If I include the
whatever part, as here
^chars(?!.*that).*this(?!.*that).*(?!.*whatever)$, sample 2 still matches, whereas this:
^chars(?!.*that).*this(?!.*that).*[^w][^h][^a][^t][^e][^v][^e][^r]$
excludes sample 2 but is horrible...
Am I missing something with the negative lookahead, or is it not possible to do such a thing ?
