LiXQuery: A Formal Foundation for XQuery Research Jan Hidders, Philippe Michiels, Jan Paredaens, and Roel Vercammen   View Paper (PDF)   Return to December 2005, Volume 34, Number 4 Abstract XQuery is considered to become the standard query language for XML documents. However, the complete XQuery syntax and semantics seem too complicated for research and educational purposes. By defining a concise backwards compatible subset of XQuery with a complete formal description, we provide a practical foundation for XQuery research. We pay special attention to usability by supporting the most typical XQuery expressions. ©2006 Association for Computing Machinery
