Abstract: Regular path expression is one of the core components of XML query languages, and several approaches to evaluating regular path expressions have been proposed. In this paper, a new path expression evaluation approach, extent join, is proposed to compute both parent-children (`/') and ancestor-descendent (`//') connectors between path steps. Furthermore, two path expression optimization rules, pathshortening and path-complementing, are proposed. The former reduces the number of joins by... (Update)
