We discuss the problem of Web data extraction and describe an XML-based methodology whose goal extends far beyond simple ``screen scraping.'' An ideal data extraction process is able to digest target Web databases that are visible only as HTML pages, and create a local, identical replica of those databases as a result. What is needed in this process is much more than a Web crawler and set of Web site wrappers. A comprehensive data extraction process needs to deal with such roadblocks such as session identifiers, HTML forms, and client-side JavaScript, and data integration problems such as incompatible datasets and vocabularies, and missing and conflicting data. Proper data extraction also requires a solid data validation and error recovery service to handle data extraction failures, which are unavoidable...
