Not sure what's the problem.

Let us do a test in http://cutesoft.net/example/xmloutput.aspx:

 

Copy the following HTML code into this example:

  <ul>
    <li>Bullet 1</li>
    <li>Bullet 2</li>
    <li>Bullet 3
          <ol>
             <li>Number 1</li>
             <li>Number 2</li>
           </ol>
    </li>
    <li>Bullet 4</li>
  </ul>

You should get the correct result: The closing tag of "Bullet 3" should appear after the closing "ol" tag, and not before the opening "ol" tag.
