Synopses & Reviews
XML is the lingua franca of the Web. All designers and developers working in a web environment need a sound understanding of XML and its role in application development. Many software packages and organizations allow for the exchange of data using an XML format. Web services and RSS feeds are now commonplace.
For those working with Flash and Flex, a thorough understanding of XML is particularly important. XML documents are one option for the data provided to SWF applications. Flash and Flex can load, display, and modify XML content. These applications can also send XML content to other applications for updating or for use in different situations.
ActionScript 3.0 introduced some fundamental changes to the way in which Flash and Flex applications work with XML. One significant change is that XML is now a native data type. ActionScript 3.0 also introduced new classes and a different framework for working with external documents. These changes are based on the E4X ECMAScript standard, and they streamline and simplify the process for working with XML in Flash and Flex.
In Foundation XML and E4X for Flash and Flex, Sas Jacobs gives you an introduction to XML and E4X. She explores the XML and XMLList classes and explains E4X expressions, providing examples for both Flash and Flex. In addition to explaining how to incorporate XML documents in Shockwave Flash?applications, Sas shows you approaches specific to Flash and Flex and explores real-world usage. The book finishes with two case studies. In the first, you will learn how to consume and display information and images from Flickr using Flash. In the second, you will work with Adobe Kuler in Flex.
Whether you are a designer or developer, this book will help you work with XML and make the transition from ActionScript 2.0 to ActionScript 3.0. It will also provide you with an excellent grounding if you are new to Flash and Flex.
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. Introducing XML and E4X in ActionScript 3.0 Including XML content in Flash and Flex applications Modifying and updating XML content using Flash and Flex In this book you'll: Understand XML and E4X Understand the new XML and XMLList classes in ActionScript 3.0 Learn to load XML content into Flash and Flex applications Understand how to create E4X expressions to target XML content Learn how to modify and update XML content with Flash and Flex Learn to consume Web services with Flash and Flex applications Who is this book for?
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 deselopers (designers who undertake some development duties), and AS2.0 developers who need to understand the new XML features of AS3.0.
This book started out as an update to my first book on Flash and XML. Originally, the idea was to update the content with the changes to XML in ActionScript 3.0. However, when it came to drafting the table of contents, I realized that there was a whole audience of Flex developers who would also benefit from a book about XML and ActionScript 3.0. Hence, this book was born So, my plan is for this book to cater to both audiences: Flash designer/developers and Flex dev- opers. I ve included common code approaches, as well as topics that are specific to each package. I ve tried to show readers how to achieve the same XML results in both software packages. This book is best suited to people who have limited experience in the areas of XML and ActionScript 3.0. It is really pitched at introductory level users who are keen to learn more about ActionScript 3.0. The book is purposely simple in its approach, showing how to achieve common tasks required for working with XML in Flash and Flex. The Flash sections show function-based approaches, whereas the Flex sections show how to work with custom classes."
XML usage changed dramatically with ActionScript 3.0 and the introduction of E4X. This has significantly streamlined the way that XML is consumed by both Flash and Flex. Because ActionScript 3.0 is common to both Flash and Flex, both key web technologies can be covered in one book.
