I'm learning regular expressions and I'm having trouble extracting the domain from the email address. I have an email address: example@gmail.com. I need to use a regular expression to extract @gmail (along with the @ symbol). I should end up only getting example. I've already tried this:

your text@(\w+) and this your text(?<=@)[^.]+(?=.).* but those expressions didn't work properly. I'd appreciate your help.

I just tried a simple look behind - @(?<=@).* it will match @google.com you can also group the entire expression and can change it according to single and multi-line matches.

@(?<=@).*
