I'm hoping you mean
use strict;
my $refhash;
foreach my $tag (%$refhash) {
print $tag, $refhash->{$tag};
}
which is very different!

It sounds like each hash element's value is an array reference, in which case
it's probably easiest to extract each one into a real array to may it
obvious what's happening. Like this
use strict;
foreach my $tag (%$refhash) {
my $refarray = $refhash->{$tag};
my @value = @$refarray;
print "$tag => [EMAIL PROTECTED]";
}
