An understanding of XML is essential when working with both Flash and Flex. ActionScript 3.0 introduces a number of changes to the way XML works in both applications. This book provides Flash and Flex developers with a coverage of XML and E4X from the ground up. If you are a developer getting to grips with XML and the new E4X commands in Flash and Flex, then this book will give you all the information that you need. It is also essential reading for developers (designers who undertake some development duties), and AS2.0 developers who need to understand the new XML features of AS3.0.
