Escaping Parentheses in Regex

Question

I have a regex which has optional anchors at the end e.g.

(\\.|,|\\/)

I am trying to add \")\" to this but if I escape it

Answer 1

Your regex should look like this: (\.|,|\/|\))

Answer 2

If you want to match one of a set of character, it's best to use a character class. And within such a class, most escaping rules don't apply.

So to match a dot, comma, slash or closing parenthesis, you can use

[.,/)]

Answer 3

\) is the correct way for escaping a paranthesis. Make sure you are properly escaping the \(\\) in the string literal.
