Twig2Stack: Bottom-up Processing of Generalized-Tree-Pattern Queries over XML Documents

Summary: Twig2Stack introduces hierarchical stack encoding and bottom-up holistic evaluation for XML twig patterns, reducing useless path matches. It directly supports generalized-tree-pattern queries while avoiding post path joins, sorting, duplicate elimination, and grouping. (summarized by gpt-5.6-luna on Jul 24 2026)
