Holistic Twig Joins: Optimal XML Pattern Matching

Summary: Proposes holistic twig join TwigStack for XML twig pattern matching, encoding root-to-leaf partial matches with a chain of linked stacks and stitching them into full matches. For ancestor-descendant patterns, TwigStack is I/O and CPU optimal among sequential algorithms that read the entire input—linear in input plus final result and independent of intermediates; B-tree augmentations enable sub-linear time; experiments validate efficiency.
