Optimize Twig Query Pattern Based on XML Schema

Abstract—Aiming at the core operation for XML data queries— Tree Pattern Queries, we propose an effective method for minimizing XML query based on XML Schema. The method can make use of the structure constraints information provided by XML Schema to optimize the tree query pattern containing the logic nodes AND and OR. Such tree pattern preferably satisfies requirements of XQuery queries describing and optimizing to support the high-performance implementation of XQuery.

Index Terms—XML, XQuery, XML Tree Pattern Queries, XML Schema.
