XML for a Tree Control

Question

I am trying to create a Tree control for my application that lists account reps as branches with their clients as leaves below them.
I created the xml below from a CGI script, but when the tree renders it the account reps are leaves and the clients don't show up at all. There is evidently something basic I am missing. Can anyone tell me what xml to do what I am shooting for should look like?

      <data>COMPID|2102</data>
    </node>
</node>
</Result>

Answer 1

At this point it is just a test application so the code is pretty small. For retrieving the data, I pretty much copied code from one of the examples. I created an HTTP request since I plan to return results from a CGI interface rather than a web service. My data provider is derived from the lastResult property of the HTTPService "userRequest".
