I actually have two questions, both are probably simple, but for some odd reason I cant figure it out... I've worked with JSON 100s of times before too! but here is the JSON in question:

{"69256":{
   "streaminfo":{
     "stream_ID":"1025",
     "sourceowner_ID":"2",
     "sourceowner_avatar":"http:\/\/content.nozzlmedia.com\/images\/sourceowner_avatar2.jpg",
     "sourceownertype_ID":"1",
     "stream_name":"Twitter",
     "streamtype":"Social media"
     "appsarray":[]
   },
   "item":{
      "headline":"Charboy",
      "main_image":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg",
      "summary":"ate a tomato and avocado for dinner...",
      "nozzl_captured":"2010-05-12 23:02:12",
      "geoarray":[{
         "state":"OR",
         "county":"Multnomah",
         "city":"Portland",
         "neighborhood":"Downtown",
         "zip":"97205",
         "street":"462 SW 11th Ave",
         "latitude":"45.5219",
         "longitude":"-122.682"
       }],
       "full_content":"ate a tomato and avocado for dinner tonight. 
                      such tasty foods. just enjoyable.",
       "body_text":"ate a tomato and avocado for dinner tonight. 
                      such tasty foods. just enjoyable.",
       "author_name":"Charboy",
       "author_avatar":"http:\/\/content.nozzlmedia.com\/images\/author_avatar173212.jpg",
       "fulltext_url":"http:\/\/twitter.com\/charboy\/statuses\/13889868936",
       "leftovers":{
           "twitter_id":"tag:search.twitter.com,2005:13889868936",
           "date":"2010-05-13T02:59:59Z",
           "location":"iPhone: 45.521866,-122.682262"
       },
       "wordarray":{
          "0":"ate",
          "1":"tomato",
          "2":"avocado",
          "3":"dinner",
          "4":"tonight",
          "5":"tasty",
          "6":"foods",
          "7":"just",
          "8":"enjoyable",
          "9":"Charboy",
          "11":"Twitter",
          "13":"state:OR",
          "14":"county:Multnomah, OR",
          "15":"city:Portland, OR",
          "16":"neighborhood:Downtown",
          "17":"zip:97205"
      }
   }
 }
}

Question 1: How do I loop through each item (69256) when the number is random? e.g. item 1 is 123, item2 is 646? Like, for example, a normal JSON feed would have something like:

{'item':{'blah':'lorem'},'item':{'blah':'ipsum'}}

the JS would be like console.log(item.blah) to return lorem then ipsum in a loop

How do I do it when i dont know the first item of the object?

Question 2: How do I select items from the geoarray object? I tried: json.test.item.geoarray.latitude

and

json.test.item.geoarray['latitude']
