XML News Editor

I’m using Senocular’s XML News Editor: http://www.kirupa.com/web/xml/examples/newseditor.htm

Great tutorial… You can add news items and display them, but as soon as you press the Reset button, they’re all gone. The XML file doesn’t change – the data being displayed is just temporarily stored…

Does anyone know a way in which I can permanently write the submitted data to the XML file so that when I open the XML file I will see the data I’ve entered into Flash then sent via PHP?
