I want to match strings that don't have abc, def or ghi. The opposite is easy:
/(abc|def|ghi)/
How do I reverse that? I don't want to
/(^abc|^def|^ghi)/
because there's going to be more 'logic' in there. (If that's even what it does.)
How do I reverse the whole group match (or whatever it's called)?
