I can't seem to find how to do not in regex. This is for Notepad++ syntax if it matters.
Thanks | If `.pdf` will only occur after `665`, the negative lookahead assertion `665(?!.*\.pdf)` should work fine. Otherwise, I prefer to use two regexs, one to match, one to fail. In Perl syntax that would be:
```
/665/ && !/\.pdf/
