And then, traversed the DOM tree, pruned the DOM tree in the light of the characteristic of Web page’s edit language. Finally, we extracted the content information from Web page. Theoretics and experiments showed that the technique could simplify the web page, present the content information to web users and supply clean data for applicable area, such as retrieval, KDD and DM from web.
