title: Robot framework get from JSON list
body: <p>I have data like this </p>
  
  <pre><code>{"_embedded":[
    {"attr_name":"attr_value_1"},
    {"attr_name":"attr_name_2"}
   ]
  }
  </code></pre>
  
  <p>and I want to get the first attribute <code>attr_value_1</code>.</p>
  
  <p>Do you know any nice way how to do it in Robot framework? Something like <code>Get JSON /_embedded[0]/attr_name</code> ?</p>
