xpath confusion

Hi List Members,

With the following xml:

<Root>
    <Keys>
         <Client id="abc">
              <a />
              <!-- a /--> 
              <b />
         </Client>
    </Keys>
</Root>

XPath: "Root/Keys/Client[@id="abc"]/ descendant-or-self::node()" 
selects 4 nodes

XPath: "Root/Keys/Client[@id="abc"]/ descendant-or-self::comment()"
selects 1 node

XPath: "Root/Keys/Client[@id="abc"]/ descendant-or-self::text()"
selects 0 nodes. 

Please can someone explain to me why the last xpath doesn't select 3 nodes.

I would like to select the 3 nodes <Client>, <a /> and <b />. Any help is
appreciated.

TIA
Bodrul
