Abstract

To deal tree pattern matching (twig query) issue for XQuery processing, TwigList [1] proposes a high efficient solution. However, it does not consider the out-of-orderness issue which is required in XQuery. And, like most existing approaches TwigList pay little attention to optimization for the parent-child relationship. In this paper, we propose a novel way to handle both the out-of-orderness issue and optimization of parent-child relationship by improving TwigList, named TwigLinkedList. Detailed performance test shows that our algorithm reaches and exceeds the level of TwigList, while reducing redundant intermediate results.
