Loading xml in jump menu

Hello friends!
I have a php file which generates an xml file. How can I make the jump menu read from that file? the idea is that the client can change the data in the admin section that’s y i made it php which will generate an xml file i used it to load photos, news etc…

how can i make the jump menu to read from such file? so that when selecting a category it will go to its url?

Thanks :slight_smile:
