Abstract:

XQuery is a language that operates on XML in its native data model, using the type system of XML Schema. By the time of the XML 2006 conference, XQuery Version 1.0 will probably be adopted as a W3C Recommendation. Like SQL, XQuery is declarative and functional, which makes it well-suited for automatic optimization. XQuery Version 1.0 is designed for querying and transforming XML data, and W3C has published a working draft of an XQuery extension for updating XML data. With an additional small extension, XQuery could be turned into a native application development language for XML, eliminating the impedance mismatch problem. An earlier paper briefly outlined such an extension, called XQueryP. This paper expands on the XQueryP proposal, adding more details, additional features such as error handling, and some use cases that illustrate the use of the extended language in various different environments.
