Tie in data with Web services and XSL Transformations

Description:In Part 5 of this tutorial series on analyzing data with XSLT, the MindMap Research Team decides to tie their data in with other services, pulling information from Amazon Web Services in response to information unearthed in the analysis. Web services provide information in XML, but it's rarely in the form that you want it, so this tutorial explains how to create an application that not only retrieves the Amazon data but also transforms it into XHTML and outputs it to the browser. The stylesheet shows how to pull XML information from multiple sources within a single transformation and also includes a device that alerts developers when Amazon changes the Web service, since changes in the feed can break the application.
