Generating tree from HTML

Your tree is grate! Really

But only one feature i still need using it. It is "generating tree from HTML".
Let's say i already have HTML code like this:

<ul>
<li>node</li>
<li>node
  <ul>
   <li>subnode</li>
  <ul>
</li>
</ul>

and i would like to create tree from it.

That feature needed to assist users with turned off javascript and so on.

P.S. I'm sorry for my English :-[
