title: How to get value from JSON list within Robot Framework?
body: <p>As part of verification in Robot Framework, I have following data (stored as <code>${response}</code>) as get request response:</p>
  
  <pre><code>{
      "interfaces": [
          {
              "name": "eth0",
              "status": "ready",
              "macAddress": "xx:xx:xx:xx:xx:xx",
              "ipv4": {
                  "mode": "DHCP",
                  "address": "127.0.0.1",
                  "mask": "255.255.255.0",
              },
              "ipv6": {
                  "mode": "DISABLED",
                  "addresses": [],
                  "gateway": "",
              }
          }
      ],
      "result": 0
  }
  </code></pre>
  
  <p>And I would like to get value of key <code>ipv4</code> and compare it with predefined value. I tried to use it out of <code>HttpLibrary.HTTP</code> as this will be deprecated for Robot Framework 3.1 so I would like to use <code>Evaluate</code>.
  Will it be possible within Robot Framework? </p>
