title: How to search JSON tree with jQuery
body: <p>I have a question about searching the JSON for the specific information. For example, I have this JSON file:</p>
  
  <pre><code> {
      "people": {
          "person": [
              {
                  "name": "Peter",
                  "age": 43,
                  "sex": "male"
              }, {
                  "name": "Zara",
                  "age": 65,
                  "sex": "female"
              }
          ]
      }
  }
  </code></pre>
  
  <p>My question is, how can find a particular person by name and display that person's age with jQuery?
  For example, I want to search the JSON for a person called Peter and when I find a match I want to display additional information about that match (about person named Peter in this case) such as person's age for example.</p>
