title: How reach json values in depth of other levels?
body: <p>Assuming that I have this JSON file:</p>
  
  <pre><code>{
      "level1" :{
          "type": "x"
      },
      "level2" :{
          "level3": {
              "level3": {
                  "type" : "Y"
              }
          }
      }
  }
  </code></pre>
  
  <p>By using <code>Jackson</code>, how can I get the type = Y value?</p>
  
  <p>It can be also reached by using <code>gson.jar</code></p>
  
  <p><strong>What I tried so far is:</strong></p>
  
  <pre><code>ObjectMapper ob = new ObjectMapper();
  String jsonContent = "...";
  JsonNode root = ob.readTree(jsonContent)
  root.path("level1");                      //return results fine
  root.path("level2").path("level3");       //not return any results
  root.path("level2/level3");               //not return any results
  </code></pre>
