Edit xml in flash

After reading this tutorial: http://www.kirupa.com/developer/actionscript/create_edit_xml.htm I wondered how can edit & write to a server hosted XML file, does anyone have working sourcefiles that I could look into?

Basically, I need following:

Read XML into flash, edit/remove nodes and it’s contents, save back the file, I undestand that I need to use some server side script since flash can’t write to the file system.

Any help is greatly appreciated.

Thanks
