hi,
I want to extract an save data from a json request like this:
 
http://map.tehran.ir/infra/maps/parcel/info?x=538632&y=3962800.5
 
I changed the registry  to get this request in Internet Explorer like Google Chrome (not download json file). Response of this request is something like this:
 
{"item": {"parcel": "39358037", "plaque": "3"}, "success": true}
 
 I want to save all of this response in a csv file, but my robot does not get response of this request. When I select the response, robot alarm me to focus on something!!. what should I do to extract data from json response??

just using pracel=urldata() works very well  
Thanks agian.
