I am working on an embedded system and my theory of the overall process follows this methodology: 1. Send a command to the back end asking for account information in JSON format. 2. The back end writes a JSON file with all accounts and associated information (there could be 0 to 16 accounts). 3. Here's where I get stuck - use JavaScript (we are using the JQuery library) to iterate through the returned information for a specific element (similar to XPath) and build an array based on the number of elements found to populate a drop-down box to select the account you want to view and then do stuff with the account info. So my code looks like this:

loadAccounts = function() 
{
   $.getJSON('/info?q=voip.accounts[]', function(result) 
   {
            var sipAcnts = $("#sipacnts");
            $(sipAcnts).empty(); // empty the dropdown (if necessarry)
            // Get the 'label' element and stick it in an array
// build the array and append it to the sipAcnts dropdown
// use array index to ref the accounts info and do stuff with it
}

So what I need is the JSON version of XPath to build the array of voip.accounts.label. The first account info looks something like this:

{
    "result_set": {
          "voip.accounts[0]": {
                     "label": "Dispatch1",
                     "enabled": true,
                     "user": "1234",
                     "name": "Jane Doe",
                     "type": "sip",
                     "sip": {
                            "lots and lots of stuff":
                            },
                     }
                  }
} 

Am I over complicating the issue? Any wisdom anyone could thrown down would be greatly appreciated.
