Using XML Menu and using load command

I am using the the drop down menu template in flash mx for my menu. Instea of the buttons opening a url, I would like to use a loadMovie command.

The command I want to use is:
[AS]

on(release){
_root.mtClip.loadMovie.(“mymovie.swf”)
[/AS]

the sytnax in the xml file is:

[AS]

How can I mmodify this to use the loadMovie command instead.

Thanks in advance…
