Regular expression to not match "www"
regex
Solution
Why regex? Isn't `text != "www"` enough?
Here it is nonetheless (uses look-ahead): `^(?!www$).*`
Problem
I guess I'm getting really weak in logic. I need to write a regular expression which matches everything except `www`. It should match `wwwd`, `abcd` and everything else, just not `www`. (Oh God, please, it shouldn't be very easy). I'm using Ruby language's implementation of regular expression. UPDATE: I need to use regular expression and not just `text != 'www'` because it is the way API is designed. It expects a pattern as argument and not the result.
