The Lixto Data Extraction Project - Back and Forth between Theory and Practice

Summary: Lixto ties database theory to scraping practice via a logic-based wrapper language (Elog/monadic datalog over trees) with formal expressiveness and complexity characterizations. Combined with a visual spec UI and a streaming Transformation Server for scalable Web-data integration. (summarized by gpt-5-mini on Feb 09 2026)
