Well, as aitap mentioned above, @jsonarray = $decoded_json->{strarray} is wrong; it should be $jsonarray = $decoded_json->{strarray}. (It makes no sense to call ref() on an array either.) Anyway, since $strarray is an array reference, you access its elements with $strarray->[$index], and if you need the whole array (in the foreach), you need to write @$strarray. (With hashes, the equivalents are $somevar->{$key} and %$somevar, respectively.) Your structure is... well, let's tackle the strarray. It is an array of a single element, and that element contains a hash. And that is where you went wrong. I think you missed the arrays altogether. There's one under pick_location and the other one was under strarray. But let's try this in code:
It's not a bad idea to postfix your intermediate variables with _href or _aref (like I did for one variable) just to remember whether you are dealing with a hash reference or an array reference. I hope this helps. I spent quite a while pondering on how to access a complex data structure that a module spat out for me, but that was quite a while ago.
