I have an xml file with duplications of elements, which I can list uniquely
fine (used the XSL example by Jenni Tennison).

The xml file looks like this:

<PROJECTS>
<PROROW>
<id>1</id>
<name>Customer 1</name>
<project_name>Project 1</project_name>
</PROROW>
<PROROW>
<id>2</id>
<name>Customer 1</name>
<project_name>Project 2</project_name>
</PROROW>
<PROROW>
<id>3</id>
<name>Customer 2</name>
<project_name>Project 1</project_name>
</PROROW>
<PROROW>
<id>3</id>
<name>Customer 2</name>
<project_name>Project 4</project_name>
</PROROW>
<PROROW>
<id>3</id>
<name>Customer 1</name>
<project_name>Project 1</project_name>
</PROROW>
</PROJECTS>

I can get the listing of Unique customers

Customer 1
      Project 1
      Project 2
      Project 1

Customer 2
      Project 1
      Project 1

However I'm unsure as to how to only list the unique Projects within these
listings.  I've checked the archives and Dawsons (but couldn't find anything
obvious).
