Abstract

This paper proposes a DOM-based Web Information Extraction solution,to get the location path of extracted infor- mation byinduction study,to edit the extraction pattern through characteristics of XPath and XSLT on data location and data transform,and according to the mapping relation between Web page's elements and DOM's nodes,to judge if the gained infor- mation sources are the same as that of the generated extraction pattern.
