I have a YQL output JSON string at this URL: YQL JSON

I found some other

I am trying to understand why I cannot get certain items out of the JSON return. For example, using jQuery, if I want the first DIVs H1 I use:

$.ajax({
       url:"http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20html%20where%20url%3D%22http%3A%2F%2Fwww.missoulaavalanche.org%2Fcurrent-advisory%2F%22%20and%20xpath%3D'%2F%2Fdiv%5B%40id%3D%22content%22%5D%2Fdiv%5B1%5D'&format=json",
       dataType: 'jsonp',
       jsonp: 'callback',
       jsonpCallback: 'cbfunc'
    });
    function cbfunc(data){
      var id = data.query.results.div;

      $('#table').append('<li>'+id.h1+'</li>');

  $('#table').listview('refresh');
}

I have tried to get some info, say the img alt or img src, from the second div… div1 like so:

function cbfunc(data){
      var id = data.query.results.div[1];

      $('#table').append('<li>'+id.img.alt+'</li>');

      $('#table').listview('refresh');
    }

I keep getting Undefined or no results… What I am missing or not understanding about getting results from the yql JSON list?

EDIT: I read a post on the YQL Blog about Cache busting… So I am using their suggestion there.

EDIT 2: here is the JSON from the yql. I would like to get div img src for example, but am not getting a return or I get an object. I think it would be data.query.results.div1.img.src

I get data.query.results.div.h1 no problem:

cbfunc({

    It’s easier than you think if you use jQuery.getJSON.

    Try this:

    $.getJSON("http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20html%20where%20url%3D%22http%3A%2F%2Fwww.missoulaavalanche.org%2Fcurrent-advisory%2F%22%20and%20xpath%3D'%2F%2Fdiv%5B%40id%3D%22content%22%5D%2Fdiv%5B1%5D'&format=json",
          function(data) {
              var id = data.query.results.div;
              $('#table').append('<li>'+id.h1+'</li>');
              $('#table').listview('refresh');
          }
);
