Question

i know that my question has been already asked many times, but even with those other topics, i still can't solve my issue...

So the question is : How can i just match this string : something.something without match anything like something.css something.jpg something.png etc... but this one have to match : something.cssblabla

What i have currently is something like that :

You could use boundary

\w+[.](?!(css|png|jpg)\b)\w+

boundary would check(not match) for any non word character(anything except \w).Hence the name word boundary

You need to use negative lookahead:

\w+\.(?!css\b)
