title: How do I retrieve values from dojo.data.ItemFileReadStore
body: <p>First, I read this short help thread here: <a href="http://www.dojotoolkit.org/forum/dojo-core-dojo-0-9/dojo-core-support/bringing-php-mysql-and-dojo-together" rel="nofollow noreferrer">CLICK</a></p>
  
  <p>It uses a JSON file built together with PHP which looks something like THIS:</p>
  
  <pre><code>{
    name: 'Italy',
    type: 'country'
  }, {
    name: 'North America',
    type: 'continent',
    children: [{
      _reference: 'Mexico'
    }, {
      _reference: 'Canada'
    }, {
      _reference: 'United States of America'
    }]
  }, {
    name: 'Mexico',
    type: 'country',
    population: '108 million',
    area: '1,972,550 sq km',
    children: [{
      _reference: 'Mexico City'
    }, {
      _reference: 'Guadalajara'
    }]
  }, {
    name: 'Mexico City',
    type: 'city',
    population: '19 million',
    timezone: '-6 UTC'
  }, {
    name: 'Guadalajara',
    type: 'city',
    population: '4 million',
    timezone: '-6 UTC'
  }, {
    name: 'Canada',
    type: 'country',
    population: '33 million',
    area: '9,984,670 sq km',
    children: [{
      _reference: 'Ottawa'
    }, {
      _reference: 'Toronto'
    }]
  },
  </code></pre>
  
  <p>So let's say I now want to "echo" all the cities in this list ... that's no problem for me! :-)
  But I'm totally confused how to access the population for example!
  How can I make a function which echos: 
  "Mexico City: population:'19 million' timezone:'-6 UTC'" for example?</p>
