flash xml demo / tutorial file. fastest/low cost wins.

I need a tutorial written in AS3 (and also as2 if possible). The tutorial is only sending me the demo files with simple commenting in the code. on a button press I need to save some variables to an XML list so that these values are remembered when I next load the file.. This will initially be used to make the following flash file: 6 circular movieclips on the stage. Their x,y and visible state is loaded from XML. pressing a button called 'edit' will allow me to drag and drop any of the movieclips. and also reveal a 'save' button. 'save' button, saves the new xy locations to the XML in edit mode all movieclips are visible but ones that will be hidden are shown by being semi transparent, or a different colour etc. Pressing save also leaves edit mode, so that when the file is played, only the visible movieclips can be seen to the viewer Should be easy to add new movieclips to both the stage and therefore the xml The above file will be the first demo. Also a much simpler demo with literally a variable which is loaded and saved to xml on a button press. The variable is your choice, maybe input text would be good. so 2 as3 files with xml please! if you have time please also make an as2 version. I'm looking for someone who has most of this code made already as I'm not asking for design, but just a snippet of code to look at. I expect everyone will have the same skill, so the fastest response will probably win
