Regex ignore succeeding word occurence

If i have these strings:

banana not included. apple included.
banana, apple included.

the regex below returns a match on both strings but I don't wan开发者_开发知识库t a match on the first string

banana.*(?<!(\bnot ))inc(\.|luded)?

What am I missing in my regex to achieve my desired result.

Thanks!

It's hard to tell from only two examples, but perhaps this is what you want?

banana(?!.*\bnot\b).*\binc(\.|luded)?

I don't have a better solution than Laurence, but to answer the why portion of your question, I believe that the .* has already consumed the not that your lookbehind is looking for.
