title: Get all nodes under YAML path
body: <p>I have a YAML file that looks like this:</p>
  
  <pre class="lang-none prettyprint-override"><code>Main:
    topofhouse:
      x: 276.4375
      y: 71.0
      z: -60.5
      yaw: -290.7768
      pitch: 35.400017
    2ndfloor:
      x: 276.5
      y: 67.0
      z: -60.5
      yaw: -8.626648
      pitch: 16.199997
    home:
      x: 276.5
      y: 63.0
      z: -60.5
      yaw: -18.976715
      pitch: -32.850002
  </code></pre>
  
  <p>Is there a way to get all nodes under <code>Main</code>?</p>
