Abstract:

Three interesting new features in XPath 2.0 and XSLT 2.0 are the item data type, the to operator, and the concept of sequences. Build a sample application that uses these features to generate a sophisticated HTML view of an XML document, and with the new features in XSLT 2.0, create shorter stylesheets that are easier to maintain. Along the way, spend a bit of time on data typing in XSLT 2.0, and learn to use the new element.
