Clash Royale CLAN TAG#URR8PPPRegularExpression: match and extract long domain
I want to match and extract domain form strings,and I got an equation:
result = re.findall(r"(^((?!-))(xn--)?[a-z0-9][a-z0-9-_]{0,61}[a-z0-9]{0,1}.(xn--)?([a-z0-9-]{1,61}|[a-z0-9-]{1,30}.[a-z]{2,})$)", text)
It does well for domain like :
example.org
example.org.eu
but it cannot work for domain like :
sub_example.example.org.eu
so,I am asking for helping improving the equation.
