The use of RSS feeds is a growing trend, and they can be found within many new websites. In ActionScript 3.0: Working with XML, instructor Todd Perkins places strong emphasis on using RSS data for blogs, podcasts, and images. He also demonstrates how to perform common tasks with XML, such as using E4X syntax, loading external data from local and remote locations, saving data, and integrating with popular services like Flickr. Exercise files accompany the course.
