Question

I’d like to be able to select, for example, some text, which is between brackets.

Let’s say, we have following text

This is a (sample (or, may be, not))  text, which I write in a browser(with keyboard)

What regex pattern should I use, which would select

(sample (or, may be, not))

and

(with keyboard)

for any number of nested brackets?

aⁿbⁿ can’t be matched with regex.

Properly parenthesized strings can’t be matched with regex either.
