How do I add XML data into an local XML file, so I can read it later.

Question

I want to save XML data into a XML file. So I can load it on the next startup.

Answer 1

Since you have tagged it under FLEX.You can use the ActionScript API for file io handling.

Answer 2

In AIR, you'll use the File and FileStream APIs to save files. See more usage info here.

These aren't available to Flash Player. You would probably use a server side solution or local shared objects ("Flash cookies").
