It is also worth pointing out that double quotes are not regular expression meta-characters and do not need to be escaped.

johngg@shiraz:~/perl/Monks > perl -Mstrict -Mwarnings -E '
open my $inFH, q{<}, \ <<EOD or die $!;
nothing
"hello"
foo "bar" quz
"hello2" "world"
foo2 "bar2" quz2 "baz" blah
blah2 "" blah3
many
lines
of
unquoted stuff
"example 1 for instance"
EOD

my $data = do {
   local $/;
   <$inFH>;
   };

close $inFH or die $!;

say qq{-->$1<--} while $data =~ m{"([^"]*)"}g;'
-->hello<--
-->bar<--
-->hello2<--
-->world<--
-->bar2<--
-->baz<--
--><--
-->example 1 for instance<--
