This paper presents the design and implementation of a novel tool to construct data-intensive Web-sites based on information sources. The key idea is to show the system some examples of Web pages and let it infer how to construct the entire Web-site. The problem is challenging, because the system allows XML to be one of information sources. Because XML data is semistructured, it is a non-trivial task to infer the intended operation from given examples. Another feature of the system is that it outputs XQuery queries, so that is can work with general XQuery engines.
