Welcome to the Monastery, indieBoy!

Please take the time to skim the Guide to the Monastery and the PerlMonks FAQ, specifically Posting on PerlMonks, to get started. Read at least Markup in the Monastery and How do I post a question effectively?
It is good practice to post one's current attempt at solving a problem. Showing one's effort makes it more likely to get help, since The Monastery isn't a "code writing service" ;-)

That said - use a Flip-Flop: 

my $pat = qr{Summary \w+\(\w\)};

while(<DATA>) {
    if (/$pat/ ... /$pat/) {
        next if /$pat/;
        print;
    }
}

__END__

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
