SXPath - Extending XPath towards Spatial Querying on Web Documents

Summary: SXPath extends XPath with spatial axes and position functions for querying rendered Web documents alongside DOM structure. Its SDOM model, formal semantics, and optimized fragments enable polynomial-time, layout-robust information extraction. (summarized by gpt-5.6-luna on Jul 24 2026)
