Here's the test case:

while (<DATA>) {
        if (/(\d)\n{2}/) {
                print "$1\n";
        }
}

__DATA__
Line 1
Line 2
Line 3

Line 5
Line 6
Line 7

Line 9

My question is, why does this not print:

3
7

[download]

As it stands, the script prints nothing. I know there are no \r or \f in the data, and just to be sure I tried matching against \W{2,}.

What am I missing here?
