| Abstract: | With the huge amount of information available online, the World Wide Web is a fertile area for data mining research. This paper addresses the issues related to data extraction from Web pages, and strongly suggests an XML-based approach for solving it. This paper describes the motivations behind converting semi-structured HTML documents into well-formed XML and presents a portion of conversion source codes that is developed based on HTML Tidy library, illustrates how to extract desired information from Web pages with XML technologies, including XHTML, XSLT and XQuery. It also discusses other aspects in the Web mining project such as data check and data integration. |
