Abstract
Xcerpt [2] and visXcerpt [1], cf. http://xcerpt.org/, are Web query languages related to each other in an unusual way: Xcerpt is a textual query language, visXcerpt is a visual query language obtained by rendering Xcerpt query programs. Furthermore, Xcerpt and visXcerpt, short (vis)Xcerpt, have been conceived for querying both standard Web data such as XML and HTML and Semantic Web data such as RDF and Topic Maps. This paper describes a demonstration focusing on three aspects of (vis)Xcerpt. First its core features, especially the pattern-oriented queries and answer-constructors, its rules or views, and its specific language constructs for incomplete specifications. Incomplete specifications are essential for retrieving semi-structured data. Second, the integrated querying of standard Web and Semantic Web data to ease the accessing of the two kinds of data in a same query program. Third, the complementary and integrated nature of the two languages.
