title: Adding xml to DOMElement from String
body: <p>I have a string with xml content, for example:</p>
  
  <pre><code>String str = "&lt;history&gt;&lt;message from="Alice" to="Bob" /&gt;&lt;/history&gt;";
  </code></pre>
  
  <p>and I want to add this xml content to some element (org.dom4j.DOMElement).
  How to do it?
  <br><br><br>
  I've tried this:</p>
  
  <pre><code>myElement.addText(str);
  </code></pre>
  
  <p>But it gives me just escaped text content.</p>
