Building light-weight wrappers for legacy Web data-sources using W4F

Summary: W4F is a lightweight toolkit for rapidly building wrappers over legacy HTML sources using declarative specifications and reusable components. Direct Java integration enables extracted content—demonstrated on IMDb—to be exposed as XML for Web information integration. (summarized by gpt-5.6-luna on Jul 24 2026)
