BLAS : An Efficient XPath Processing System

Summary: BLAS is a Bi-LAbeling system for XPath over XML, using P-labeling for child axes and D-labeling for descendant axes. Labeled storage with indexing enables fast descendant traversal; three SQL translations and two engines yield gains vs D-labeling XPath. (summarized by gpt-5-nano on Feb 09 2026)
