This chapter has covered the majority of E4X's core functionality, but completely exhaustive coverage is beyond the scope of this book. For further study, see the methods and variables of the XML an XMLList classes in Adobe's ActionScript Language Reference. For deep technical details, consider reading the E4X specification at http://www.ecma-international.org/publications/standards/Ecma-357.htm.
Up next, we'll explore Flash Player security restrictions. If researching Flash Player security isn't your idea of a good time, you might want to consider skipping ahead to Part II, where we'll learn how to display things on screen. Just remember that Chapter 19 is there to help if you find yourself faced with security errors during development.
