Dear all,

I have a large hash where every key in the hash is of the format:\w\d\d, and I want to use keys to extract an array of keys that match any \d\d pattern, (hence ignoring letters) like so: 

my $r = 44;
foreach my $key (keys %{$self->{'residues'}{$modelCount}{/^\w$r$/}}){
        print $key."\n";
}

This doesnt work as it is, but is there a possible solution, or should I just step through the keys ahd store an array of the ones that match?

Cheers
Sam
