Ok, that helps. If your files are indeed line-based (i.e., your patterns do not span multiple lines), then I suggest processing them line-by-line:

use File::Slurp;

my @myHashArray = ( { toFind => qr/(?i)foo/, toReplace => 'bar' } );
my $counter = 0;

my $name = 'data_file'; # $File::Find::name
for my $line (read_file('data_file', chomp => 1)) {
    $counter++;
    my $orig_line = $line;
    $line =~ s/$_->{toFind}/$_->{toReplace}/g for @myHashArray;
    next if $line eq $orig_line;
    print "LOG: $counter $name\n";
    print "LOG: \t Original line: $orig_line\n";
    print "LOG: \t Replaced line: $line\n";
}

Here I've replaced LOGFILE with a LOG: prefix for ease of testing, and eliminated the reliance on File::Find for the same reason.

With the following data_file:

Foolius Caesar
Footholomew Cubbins
No changes here
Just another barrage of text

I get the following output:

LOG: 1 data_file
LOG:      Original line: Foolius Caesar
LOG:      Replaced line: barlius Caesar
LOG: 2 data_file
LOG:      Original line: Footholomew Cubbins
LOG:      Replaced line: bartholomew Cubbins

Does that help?
