[jQuery] Best method for detecting the depth of childed ordered list...


I'm trying to get the "depth" of an ordered list. I need to know what the
"deepest" branch of the list is. My data looks like:
<ul>
<li>
Item 1
<ul>
    <li>
Item 1.a
</li>
    <li>
Item 1.b
</li>
</ul>
</li>
<li>
Item 2
</li>
<li>
Item 3
<ul>
    <li>
Item 3.a
<ul>
<li>Item 3.a.i</li>
<li>Item 3.a.ii</li>
<li>Item 3.a.iii</li>
</li>
    <li>
Item 3.b
</li>
</ul>
</li>
<li>
Item 4
</li>
</ul>
I need to know that the deepest branch is 3 nodes deep (i.e. Item 3.a.i). I
can get this using recursion or loop through all the <ul> nodes, but I'm
wondering if I'm missing an obviously selector that will get me the same
information.
