Creating an Online RSS News Aggregator with ASP.NET

"Learn about displaying XML data in an ASP.NET Web page using the XML Web control to retrieve remote XML data, and about using the Repeater control to emit XML data from a database. With the ever-increasing demands of data sharing among disparate platforms, the use of XML has exploded over the past few years. Realizing this trend, Microsoft made sure to include robust XML support throughout the .NET Framework. For ASP.NET developers, this means that displaying and working with XML data in a Web page has never been simpler. Throughout this article we'll learn about XML and ASP.NET by building an RSS 2.0 syndication engine and an online news aggregator."
