This tutorial will provide a detailed technical introduction to both XQuery 1.0 and XSLT 2.0, and their shared language XPath 2.0. The XQuery section will provide attendees with a solid understanding of the syntax of XQuery expressions. The discussion of XSLT will focus on new features in 2.0, such as grouping, sequence construction, and user-defined functions. The session will also compare and contrast XQuery and XSLT and describe their most appropriate use cases.
