Hello community!
I'm dealing with saving to XML , but having problems with building an array which is then written to XML, i have no experience at all with working with XML and not that much with classes! If anyone have any suggestions on this script below, they are most welcome! i've added **'templist = myData;'** this works together with the **'var templist : Object = new Object(); '** but of course it doesn't act as an array. i've tried hard...real hard (20+ hours)
