Hello, I need to match a string like this: "one.two.three". Each title is separated by a ".", and there must be at least one title, but the others are optional. Here is my attempt: 
while ("one.two.three" =~ /([A-Za-z0-9_].+)\.?([A-Za-z0-9_].+)?/g) {
    print "$1\n";
}

Thank you for any help you can give.
