I feel like there must be a more elegant way to do this. I'm getting data from an online service, and sometimes I get a result with 1 hash, and other times a list of hashes. So what I'm doing now is: 
if ($content->{Addresses}{ArrayOfAddressResponse}{AddressResponse} =~ 
+/HASH/) {

foreach my $response ( keys %{$content->{Addresses}{ArrayOfAddressResp
+onse}} ) {
...do stuff...

and then 
if ( $content->{Addresses}{ArrayOfAddressResponse}{AddressResponse} =~
+ /ARRAY/) {

foreach my $response ( @ {$content->{Addresses}{ArrayOfAddressResponse
+}{AddressResponse}} ) {

The thing is, the "stuff" I'm doing ends up looking identical like: 
        print "street: $response->{Street}<br>";
        print "street2: $response>{Street2}<br>";
        print "apt: $response->{UnitNumber}<br>";

So it just seems very wasteful. I've thought about just making all the print statements a subroutine. But it's the two "if" statements that seem kinda clunky to me. Any input would be greatly appreciated (again)!
