Regex gets domain name from email

Question

I learn regular expressions and cannot receive googlefrom email address

line

[e-mail]

I just want to get Google, not Google.com

Regex:

[^@].+(?=\.)

Result: https://regex101.com/r/wA5eX5/1

From my understanding. This ignores @finding the line after this until .(dot) using(?=\.)

What have I done wrong?

Answer 1

[^@]means "match a single character that is not familiar @. This is not what you are looking for - use lookbehind (?<=@)for @and your (?=\.)lookahead for \.to extract the server name in the middle:

(?<=@)[^.]+(?=\.)

[^.]+ " ".

Demo.

You can get the name sumdomain (without a top-level domain, for example: .comor .com.mx) by adding search operators (but it will match twice in [e-mail]):

[^.@]*?(?=\.\w{2,}$)|[^.@]*?(?=\.com?\.\w{2}$)
