Efficient Algorithms for Evaluating XPath over Streams

Summary: Proposes two streaming XPath algorithms, LQ (lazy) and EQ (eager), for Univariate XPath over streams. They achieve the O(|D||Q|) streaming time bound in one pass—the first to do so; EQ offers optimal buffering-space, and experiments show practical gains over prior stream-querying methods.
