I. Qi and M. Liu (Canada)


XML, Query Language


With the wide adoption of XML, a fundamental need is to provide an easy-to-understand, easy-to-use, and power ful query system for the advanced use of XML over the Internet. This paper describes our design and implementa tion of an XML query system based on a novel declarative XML query language XML-RL. It not only provides a very simple but expressive query language for retrieving XML information, but also allows advanced processing of XML documents, such as logic deduction, integration, and trans formation.
