Zheng Jiao-ling · Journal of Chengdu University of Information Technology · 2007
The DOM is used to analyze the web page and the recursive algorithm of the depth-first search(DFS) is used to traverse the DOM tree.By transforming the HTML document into DOM tree the method assign an exclusive tab to each node of the tree to analyze the webpage.In order to analyze the webpage structure more intuitively a method displaying the tree structure of the webpage in graphical form is adopted.The method can satisfactorily analyze the nest structure of the webpage tags and precisely match the DOM tree structure into which the webpage transforms.Thus the goal for precise webpage analysis and webpage node location is achieved.
