Regex no character

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 warningone except warning.gif.

I can’t get him to include the last one that has no character (control or other) after it.

using warnings?[^\.]gets what I want, except for the last warning (in the last line). I think because after that there is no character. How can I make it turn on this one?

Answer 1

If you have negative images, you can use this:

/warnings?(?!\.gif)/

This should work in Javascript.

Answer 2
