Is it posible to send data from flash to xml?

Is it possible to alter the content of an xml file form flash??
If it is where can I PLEASE find a sample?
I have spent three day’s looking…

I followed an awesome tutorial on how to interact with flash and xml on the kirupa site, including save to xml from flash. I am though getting stuck on the last part. How do I get the swf file to override the xml file permanently so that when I close and reopen the swf it will call the altered content from xml, it should not reset back to the original content?? Please excuse my ignorance, but I’m new to this.
This is what I got so far… http://doubleumedia.co.za/working_folder/xml/simple_editor.swf

I have also included all the files… http://doubleumedia.co.za/working_folder/xml/simple_editor.zip
Please tell me what I’ am doing wrong.
