Two of the five applets which are included in this set allow the user to choose from multiple RSS feeds. These RSS feeds can be set in the external XML configuration file. You should use a good text editor, like Textpad (www.textpad.com), to edit the XML files. For the two RSS readers which allow multiple feeds, the selected feed is greyed-out. There is no limit to the number of possible feeds for the combo list. Each feed includes a configuration XML file to control common options like text and background colors. Thus, you can make the RSS reader match your website look (to some extent) without even touching the Flash code. Each XML file includes a DTD file, which can be used to validate your XML syntax. 100% of the Flash source code is included with your purchase, including all .fla and .as files. Flash 2004 Professional is required to edit the Flash source code. These readers require PHP, and the ability to use file-reading and file-writing functions in PHP.
