title: parsing complex json jquery
body: <p>I'm trying to getJSON the following json data:</p>
  
  <pre><code>{
    "count": 96,
    "value": {
      "title": "cotripWeatherStations",
      "description": "Pipes Output",
      "link": "http:\/\/pipes.yahoo.com\/pipes\/pipe.info?_id=f43ccc14ab9d1c88d537236e93c1525e",
      "pubDate": "Mon, 03 Sep 2012 02:17:48 +0000",
      "generator": "http:\/\/pipes.yahoo.com\/pipes\/",
      "callback": "",
      "items": [
        {
          "ws:Location": {
            "global:Latitude": "37.086807",
            "global:Longitude": "-104.521294"
          },
          "ws:Device": {
            "global:DeviceId": "6796",
            "global:CommonName": "025N008  RATON PASS (RWIS)",
            "global:Status": "enabled",
            "global:EntityId": "1",
            "global:RoadId": "31",
            "global:RoadName": "I-25",
            "global:Direction": "North",
            "global:MileMarker": "8",
            "global:LastUpdateDate": "2012-08-26T13:52:00.000-06:00",
            "global:Icon": "theme\/cotrip.org\/images\/devices\/icon_device_weather_station_with_cam_16x23.gif"
          }
        }
     ]
  }
  </code></pre>
  
  <p>the following code gives me an alert with output, but no data:</p>
  
  <pre><code>var weather = $.getJSON("http://pipes.yahoo.com/pipes/pipe.run?_id=f43ccc14ab9d1c88d537236e93c1525e&amp;_render=json&amp;_callback=?", function(json) {
    alert("JSON Data: " + json.value["items"]);
  });
  </code></pre>
  
  <p>how do I traverse further into this JSON to 'ws:Devise - "global:CommonName"</p>
