Abstract: Tree pattern matching is one of the most fundamental tasks for XML query processing. Prior work has typically decomposed the twig pattern into binary structural (parent-child and ancestor-descendent) relationships or paths, and then stitch together these basic matches by join operations. In this paper, we propose a new algorithm that explores both the document tree and the twig pattern in a bottom-up way and show that the join operation can be completely avoided. The new algorithm runs in O (|T|×|Q|) time and O (|Q|×leafT) space, where T and Q are the document tree and the twig pattern query, respectively; and leafT represents the number of leaf nodes in T. Our experiments show that our method is effective, scalable and efficient in evaluating twig pattern queries.
