Research on Web Information Extraction Based on XML

摘要

The standard XML technology is used for Web information extraction in this paper, and a generic XML-based Web information extraction solution is proposed. In the extraction process, two key technologies are proposed and implemented: the XML-based Web data conversion technology and the DOM-based XPath generation technology, to simplify the information extraction work. XSLT is used as the description language of extraction rules, which is conductive to the unity of extraction patterns.
