Abstract
This paper illustrates some aspects of the visual wrapper generation tool Lixto and describes its internal declarative logic-based language Elog. In particular, it gives an example scenarioand contains a detailed description of predicates including their input/output behavior and introduces several new conditions. Additionally, entity relationship diagrams of filters and patterns are depicted and some words on the implementation are issued. Finally, some possible ramifications are discussed.
All methods and algorithms of the Lixto system are covered by a pending patent. For papers on Lixto and further developments see www.lixto.com.
