Add to ORKGIn this paper we present the World-Wide WebWrapper Factory (W4F), a Java toolkit to generate wrappers for Web data sources. Some key features of W4F are an expressive language to extract information from HTML pages in a structured way, a mapping to export it as XML documents and some visual tools to assist the user during wrapper creation. Moreover, the entire description of wrappers is fully declarative. As an illustration, we demonstrate how to use W4F to cre- ate XML gateways, that serve transparently and on-the-fly HTML pages as XML documents with their DTDs
