Context Free Forums and Gallery

Hi! Thanks for a wonderful program, it's really nice to use. I've been playing around a bit with javascript and svg, creating something similar.

Give it a try if you want to. The grammar is a bit weird since I just load javascript code. =)

contextfree with svg

I've tried it in firefox and safari.

Is it possible to add elements to an xml file permanently using javascript?
I am using the examples on w3schools and as far as i can tell creating or adding an element with javascript only makes that element accessible through javascript. I want to actually write a new element in to my XML file. How can i do this?
