Relational Databases for Querying XML Documents: Limitations and Opportunities

Summary: Evaluates a conservative relational approach to XML: DTD-guided shredding, XML-to-SQL translation, and result reconstruction. Reveals which semi-structured query semantics relational engines cannot capture and proposes relational extensions to address them. (summarized by gpt-5.6-luna on Jul 24 2026)
