This great (7 page) tutorial from Kirupa.com shows you how to use XML in Flash CS3 – which involves using some ActionScript 3.0 code. If you’ve used XML in the earlier days of Flash, some of this will feel familiar to you. However, Kirupa shows you some time-saving techniques that ActionScript 3.0 allows you to take advantage of. You learn a bit about XML structure, how to read the XML (using code), and finally how to filter some data.
This is a particularly excellent tutorial if you’ve used XML and ActionScript with Flash, and need to update your skills for Flash CS3 and ActionScript 3.0.
