title: Getting a tree node using the name and not the position
body: <p>How to get a child tree node using the name and not the range of the node in the child node list .</p>
  
  <p>i found this method but it uses the position of the element in the children list:</p>
  
  <pre><code>selectedNode.getChildren().get(i).
  </code></pre>
  
  <p>Many thanks </p>
