When XML documents are modeled as graphs, many research issues arise. In particular, there are many new challenges in query processing on graph-structured XML documents because traditional query processing techniques for tree-structured XML documents cannot be directly applied. This paper studies the problem of structural queries on graphstructured XML documents. A hash-based structural join algorithm, HGJoin, is first proposed to handle reachability queries on graph-structured XML documents… CONTINUE READING
