The engine was de- signed to provide very high performance for mes- sage processing applications, i.e., for transform- ing XML data streams, and it is a central com- ponent of the 8.1 release of BEA's WebLogic In- tegration (WLI) product. This XQuery engine is fully compliant with the August 2002 draft of the W3C XML Query Language specification. A goal of this paper is to describe how an ef- ficient, fully compliant XQuery engine can be built from a few relatively simple components and well-understood technologies. ©2004 Association for Computing Machinery
