oops that should have been
@sorted_keys = sort { $hash{$a}[1] cmp $hash{$b}[1] } keys %hash;

yes:
@sorted_keys = sort { $hash{$a}[2] cmp $hash{$b}[2] } keys %hash;

Subject: sort on anonymous array elements as hash values
my %hash = (
'keyone' => ['firstvalueone', 'firstvaluetwo],
'secondkey' => ['anothervalueone', 'valuetwoforsecondkey'],
'keythree' => ['thirdvalueone', 'thirdvaluetwo']
);
Can I sort the hash on the second element of the anonymous array?
Output should be:
firstvaluetwo
thirdvaluetwo
valuetwoforsecondkey
Many thanks in advance,
Birgit Kellner
