摘要：

By studying the structure of HTML documents, this paper solves the problem of web information extraction through the standard XML technology and poses an information extraction method based on XML: construct HTMLDOM tree to implement Web cleaning and generate XHTML documents by analyzing HTML web, then analyze the XHTML files through the Xerces-J's DOM methods and construct an XPath generation algorithm; use the advantages of XSLT and XPath technology in the aspects of data location and conversion to automatically learn and generate the information extraction rules and implement the Web information extraction according to the generated XPath.
