Assuming constant delimiters, a simpler solution: 

#!/usr/bin/perl -w
use strict;

sub process {
   my ($data) = @_;
   print($data);   # Or whatever
}

my $start = '*start*of*junk*data*';
my $end   = '*end*of*junk*data*';


my $qfn = "file";
open( my $fh, '<:raw:perlio', $qfn )
   or die("open $qfn: $!\n");

for (;;) {
   $/ = $start;
   my $good = <$fh>;
   last if !defined($good);
   chomp($good);
   process($good);

   $/ = $end;
   my $junk = <$fh>;
   last if !defined($junk);
}
