if you are using PHP you could do what i did (had a little help with it just the other day). Php json output - what am i doing wrong?
You basically use php to convert the json data to an array that you then have to loop through at which point you can get it to match things or omit things based on any variables you want to set. So you could look for a specific ‘name’ or ‘url’ in your case.
