XSLT is a powerful language to transform XML documents into other documents or plain text documents. Attached to this "article" are three files. The .wsf-file is a Windows Scripting Host file, that contains some VB-script to apply the XSL-file to the XML file. Just double click it in Windows, and it should display a dialog box with the XML transformed into a table.
There is a small, but good tutorial at W3Schools, or you could dig into the "XSL Transformation Recommendation".
