This paper describes the design, implementation, and performance characteristics of a commercial XQuery processing engine, the BEA streaming XQuery processor. This XQuery engine was designed to provide high performance for message-processing applications, i.e., for transforming XML data streams. The engine is a central component of the 8.1 release of BEA’s WebLogic Integration (WLI) product. The BEA XQuery engine is fully compliant with the August 2002 draft of the W3C XML Query Language specification and we are currently porting it to the latest version of the XQuery language (July 2004). A goal of this paper is to describe how a fully compliant yet efficient XQuery engine has been built from a few relatively simple components and well-understood technologies.

Currently, the most effective standard used for data exchange over the Internet is the eXtensible Markup Language (XML). The greatest strength of XML is, it can represent many different kinds of information from diverse sources including structured and ...
XML Processing and Data Integration with XQuery

Most Web applications exchange data as XML, but they create and process this data with languages that don't have native support for XML. With appropriate middleware, XQuery can dramatically simplify this process, treating all data sources as though they ...
