title: Read Array Value Using Dataweave in Mule
body: <p>I am trying to use dataweave in Mule to read specific data values from an incoming payload. My sample payload looks like below:</p>
  
  <pre><code> {
      "source": [
          {
              "uri": "entities/1R6xV",
              "createdBy": "API_USER",
              "createdTime": 1562504739146,
              "attributes": {
                  "label": "000000000002659654",
                  "value": {
                      "Name": [
                          {
                          }
                      ],
                      "Id": [
                          {
                          }
                      ],
                      "Number": [
                          {
                              "type": "config/Types/Number/attributes/Number",
                              "ov": true,
                              "value": "000000000002659654",
                              "uri": "entities/1R6xV/attributes/Num/1ZtyT/Number/60pvN6"
                          }
                      ]
                  }
              }
          }
      ]
  }
  </code></pre>
  
  <p>If I need to read the "label", I can achieve that by</p>
  
  <pre><code>label: payload.source.attributes.label
  </code></pre>
  
  <p>Similarly, how can I read the "value" under attributes > Number. It doesn't work by:</p>
  
  <pre><code>Value: payload.source.attributes.Number.value
  </code></pre>
  
  <p>I am new to Dataweave. Please advise.</p>
