I'm creating a toc from an xml document based on a folder and it's
child folders and files. From this list I need to Create an Alphabet
style Table of Contents. No problem there. Where I'm getting stuck is:

If the character does not exist in the list,, I need the alpha
character added, just not linked.

<root path="C:">
 <dir path="C:\test">
   <dir path="C:\test\-- A --">
       <file name="apple.xml"/>
   </dir>
  <dir path="C:\test\-- O --">
       <file name="orange.xml"/>
  </dir>
 </dir>
</root>

OK, now from the xml above I would want my htm output to look
something like this

<p><a href="#A">A</a> B C D E F G H I J K L M N <a href="#O">O</a> P Q
R S T U V W X Y Z</p>

I can match on the dir/dir and and parse out A and O, but any ideas on
how to put in the rest of the characters that do not match any of the
Alpha's in my file?
