36 digit string extraction Can't Post

I have gotten wonderful help from this forum on a problem earlier, but I'm about 98% to a resolution. My objective is to extract the first 36 digit string from each file with a .wmk extension in a directory. The script that I got help for this is as follow:

my $found = {};
my $new = 'C:\Search Express\output.txt';
my $dir = 'C:\Search Express\OGC Images';

opendir DIR, $dir or die $!;

for my $file (grep { /\.WMK$/ } readdir(DIR)) {
open FILE, "$dir/$file" or die $!;
while (<FILE>) {
if (/\b(.{36})\b/) { #I think the problem is this line.
$found->{$file} = $1;
last;}
}
close FILE;
}
close DIR;

if (scalar keys %$found)
{
open FILE, ">$new" or die $!;
print FILE join "\n", map { "$_ $found->{$_}" } keys %$found;
close FILE;
}

The following is a sample of file content:

uniqueID parent class dateCreated dateMostRecentUpdate expirationDate size pageCount familyID resolutionID targetClass deleteInProgress version documentName account template createdBy mostRecentUpdateBy description format all.kw all.user
A6C0BDB4-92A9-11D1-96F8-00805FE246D4 37AD20C7-5232-11D1-96EE-00805FE246D4 3 19980122000000000 19980122000000000 20790604000000000 0 0 A6C0BDB4-92A9-11D1-96F8-00805FE246D4 0 3 0 0 Perkins, Annettee Watermark ogc ogc
  • The results of running the script yields the following:


8040.WMK dateMostRecentUpdate expirationDate
240.WMK dateMostRecentUpdate expirationDate
0.WMK dateMostRecentUpdate expirationDate
9200.WMK dateMostRecentUpdate expirationDate
  • Ideally, it should look like this:


1000.WMK A6C0BD67-92A9P11D1-96F8-00805FE246D4

Any help on this would be greatly appreciated.

Thanks

My answer to my reply: The problem was just where I thought it was. The modification to the code is as follow:

if (/\b([^ \t]{36})\b/) {
