XML trees are like family trees so the root is normally shown at the top and
the descendants are underneath. I think //menuItem[pageID = $id] will get
the nodes you need, where $id contains the chosen pageID such as 938.

Hmm...I don't think I fully explained what I was looking for very well.
;o)
We store out entire site structure in XML. We want to make an RSS feed
that will return the most recently updated pages that fall underneath a
specific node of the menu.
So, if my structure was:
Home
About
- staff
- - mary
- - bob
Contact
Downloads
I want to be able to say "grab the recently updated pages in the 'staff'
section" so I only want to grab staff, mary, and bob, and then sort them
by date.
The more I look at this, the more I'm confused as to if I want to select
descenders or ascenders in the match statement. It appears I could use
both methods via different syntax?

Hmm...that doesn't quite work either. Here's some specific Xml:
<menuItems>
<menuItem>
<pageID>938</pageID>
<browserTitle>Home Page</browserTitle>
<lastUpdate>2006/06/12</lastUpdate>
<menuItem>
<pageID>998</pageID>
<browserTitle>District Administration</browserTitle>
<lastUpdate>2006/06/06</lastUpdate>
</menuItem>
</menuItems>
I want to pass in the pageID of '938' and, as such, grab both nodes in
the above XML.
I think, in english, I want to say "grab every menuItem that has a
pageID of 938 or is a child of a menuItem with a pageID of 938"
Said that way, I should probably use descendants. I think I'm confused
between the concept of 'is a child of' vs. 'has a parent of'.
