Man... thanks a lot.. i am trying to find useful info abt JSON and perl and this is pretty much the only one with some practical information. I still have not understood it completely but my sincere thanks. can u explain it to me wat exactly happens when u convert from json to perl obj. im lost in all the hashref and arrayref you are talking abt. Is it the object's structure that you are talking abt? if you could enumerate i would be grateful. thanks
