I will drill in on a specific example so I can compare and contrast XSLT versus ASP.NET. The example is the MSDN TOC. MSDN found that XML was ideal for managing its large table of contents (TOC). The contents of this TOC come from hundreds of groups around the company. The XML format provided a way to glue together disparate back-end processes that would have been much harder to change. XML/XSL also made it possible to reach different browsers on different platforms.
