[jQuery] How to clone an element to a sub element within itself ?


Hi all,
I have a two level list :
<ul>
<li>
<a href="" class="to be copied"></a>
<ul>
<li></li>
...
</ul>
</li>
<li>
<a href="" class="to be copied"></a>
<ul>
<li></li>
...
</ul>
</li>
I want to take all the first level a and copy them as the first
element in the list:
<ul>
<li>
<a href="A" class="to be copied"></a>
<ul>
<li><a href="A" class="copied"></a></li>
<li></li>
...
</ul>
</li>
<li>
<a href="B" class="to be copied"></a>
<ul>
<li><a href="B" class="copied"></a></li>
<li></li>
...
</ul>
</li>
I know how to select each a item:
jQuery("ul ul").siblings("a")
I would know how to wrap the li around them and clone them, but once
done, I don't know how to put each of them below their list.
I've tried using .prependTo, but it copies (rightly) all the links
below every item.
Do you have any suggestion ? I'm stuck and I fell like I'm missing
something obvious.
Any idea or link to the doc I missed more than welcome!
