You could probably make the first regex use a non-greedy .*

Wouldn't help. 

>perl -E"$_='nor neither nor'; say !/neither.*nor/ && /nor/ ?1:0"
0

>perl -E"$_='nor neither nor'; say !/neither.*?nor/ && /nor/ ?1:0"
0

Non-greediness is very fragile and frequently misused.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.

            For:     Use:
