This creates a hash where the key is a regex search, and its value is the replacement. I don't know why backreferencing isn't working.

Where the search string (key) is: <CM>HTMLINSERT:<img src=([^>]+)></CM>

The replacement (key's value) is: <figure><graphic url=$1/></figure></p>

Given the following input from TEXTFILE: The quick <CM>HTMLINSERT:<img src="grab me!"></CM> brown fox

My OUTFILE reads: The quick <figure><graphic url=$1/></figure> brown fox

And what I want is: The quick <figure><graphic url="grab me!"/></figure> brown fox

open FSR, "ultimate_fsr.txt" or die "Couldn't open file: $!";

my %fsr_hash = ( );
my $search = undef;
my $replace = undef;
while (<FSR>) {
    ($search, $replace) = ($_=~m/"(.*?)" "(((\\")|[^"])*)"/);
        if ($search ne '' && $replace ne '') {
              $fsr_hash{$search} = $replace;
    }
}

open TEXTFILE, "test_file.txt" or die "Couldn't open file: $!";
open OUTFILE, ">output.txt" or die "Couldn't open file: $!";
while (my $line = <TEXTFILE>) {
    foreach my $key (keys %fsr_hash) {
    $line =~ s/$key/$fsr_hash{$key}/g;
        }
        print OUTFILE "$line";
}
