Below is sample Data I have.
Columns are
    CategoryID,
    CategoryName
    TreeView
    OrderView

3 List C0ntrol           1      01.00
 7 Item Manipulation  11    01.01.00
 4 TreeList                 1      02.00
 8 Item Manipulation  11    02.01.00
 9 Tips and Tricks      11    02.02.00
 5 Message Board     1      03.00
 6 Outlook Control    1      04.00

I am wondering if there is a quick and dirty way to create nested LI's based 
off of the following data
sample output would be
<ul>
    <li>list contorl
        <ul>
            <li>Item Manipulation</li>
        </ul>
    </li>
    <li>TreeList
        <ul>
            <li>Item Manipulation</li>
            <li>Tips and Tricks</li>
        </ul>
    </li>
    <li>Message Board</li>
    <li>Outlook Control</li>
</ul>

I am hoping there is a straight forward method to iterating through the 
items.
I have also wondered if maybe there is a way I can select all items that 
have a string-length of 1
iterate through that list
    and for each item in the list grab the Substring of OrderView Length Of 
TreeView * 3
    and then select all Items that are begin with it
or match a set pattern
    02.??
so that it would match 02.00 , 02.01, 02.02 but not match 02.01.01

I somehow get the feeling that the last methid would be nigh to impossible 
with XPath. Look forward to any comments and/or suggestions and/or pointers
