Question

In this text:

warning here
there are several types of warnings
in this string warning.gif
at the end warning
end of line warning

I want to match every warning except warning.gif.

I cannot seem to get it to include the last one that has no character (control or otherwise) after it.

using warnings?[^\.] gets what I want except for the last warning (on the last line). I think because there is no character at all after. How can I get it to include that one?

Answer 1

If you have negative lookaheads you can use that:

/warnings?(?!\.gif)/

This should work in Javascript.
