XML is emerging as a de facto standard for information representation and data exchange over the web. Evaluation of twig queries, which allows users to find all occurrence of a multiple branch pattern in an XML database, is a core and complicate operation for XML query processing. Performance of conventional evaluation approaches based on structural join declines with the expansion of data size and query complexity. In this paper, a novel approach is proposed to compute twig queries with matching twig query automata and path schema trees. Moreover, we give the performance evaluation to demonstrate the high performance of our approach.
