Saving XML in AS3.0

I´m doing a program in flash with as3.0 that loads a XML file in the begining and put it in to a var, edit some data in it and in the end i 开发者_开发百科need that the program overwrite the original file.

Saving Files on a local machine is only possible within an AIR Application.

If you write a Flash / Flex Application that should run within the browser you have to send your xml to a server that saves it. Probably you choose some PHP Server Script to do so.
