Chapter 23. Introduction to XML

Right now, eXtensible Markup Language (XML), is king among buzzwords. From the hype surrounding XML, you would think that it could whiten whites, make curly fries, and stay crunchy even in milk! In reality, though, XML isn’t nearly that infomercial-worthy. Instead, XML is about something that at first glance seems a bit boring: data.

In this chapter, you’re going to take a look at these related topics:

  • What XML is. XML is one of the hottest topics in Web development today. You’ll get a look at the good, the bad, and the ugly when it comes to XML and Flash.

  • How to load and send XML. If you’re going to use XML, you first have to learn how to load XML into your Flash movie and how to send the XML from Flash to another application.

  • How to move through the XML tree structure. Navigating through the XML tree structure is a little different than anything you’ve done before. You’ll become acquainted with the XML family tree—including parents, children, and siblings.

  • How to use WDDX and XML together. Web Distributed Data Exchange (WDDX) enables you to exchange complex data structures between different programming languages by converting the structures to XML (serialization) and then converting the XML data back into a native structure (deserialization).

So the question becomes, what is this XML stuff and what does it have to do with Flash? Before you can even begin to think about integrating Flash and XML, you need to know a bit more about XML itself.
