In this article, I've shown you how to create a syndicated feed reader that retrieves a single remote feed, transforms it using XSLT, and displays it as part of a Web page. The system can also adapt to multiple feed types through the use of XSLT stylesheets.
The application uses a DOM Document to analyze the feed and determine the appropriate stylesheet, but you can further extend it by moving some of that logic into an external stylesheet. You can also adapt the system so that it can pull more than one feed, perhaps based on a user selection, with each one creating its own cached file. Similarly, you can enable the user to determine the interval between feed retrievals.
