How to set default option when loading combo via XML

I am loading a dhtml combo via a web method that returns XML. I need to be able to specify the default selected value in the XML itself. Is that possible? I have tryed “Selected” and “SELECTED=selected”… nothing seems to work.

Below is an example of the XML I am using to populate the combo box. How would I make the 3rd item selected by default?

<?xml version="1.0" encoding="utf-8"?> All Calls (No Restriction) Local Calls This Month Calls For This Month Drew's Calls Today

To get a correct xml please define an attribute as follows:

Local Calls This Month
