Regex not to escape just < > =?

Question

I currently have the following regex:

"/([^\w\.\,]+\s*)/"

It escapes, letters, numbers, commas and dots followed or not by space. How do I let it escape everything except the characters: < > = !

You want to marry only the characters < > = ! that?

Yes, only those characters, whether or not followed by space

Try this, it will make him accept only the characters < > ! =:

/[<>=!]/g

Already this will make him accept everything except the characters < > ! =:

/[^<>=!]/g

It worked, so too (which I did according to your previous answer) [(<|>|=|!)].

Parentheses and | inside brackets are taken literally, not as special syntax. This regex also does not accept (, | nor ). If you want to deny a character set, simply do /[^<>=!]/g. P.S. And the comment of @Leonardovilarinho accepts (, | and ) when you shouldn’t accept.
