$string='dns\.support.dnsbed.com';
print "$string\n";
if ($string =~ /^(.*?)\\\.(.*?)(?<!\\)\.(.*)$/) {
print $1.".".$2."@".$3;
}
Output:
dns\.support.dnsbed.com
dns.supp...@dnsbed.com
我猜你遇到的是转义的问题。。。

Subject: Help with a regex
Hello,
I have a string like: dns\.support.dnsbed.com I want to translate it to a
regular email address: dns.supp...@dnsbed.com
if ($string =~ /^(.*?)(?<!\\)\.(.*)$/) {
my $user = $1;
my $tld = $2;
return $user . '@'. $tld;
}
But this won't work correctly. I got:
d...@support.dnsbed.com
Where do I get wrong? Thanks.
