The advent of the networks information era has increased the content of information within the internet in exponential mode,so it makes the research on how to extract useful information from the internet in an efficient way become an important topic in network information retrieval domain.Based on two basic features of web pages,the visibility and the unification,in this paper we put forward a new algorithm which separates the webpages to blocks using the detection separator bars.The use of the conception of typesetting in relative position solves the problem of how to express the relative positions of each page blocks under the circumstances that the heights of them are partly unknown.By computing the number of blocks,the length,width and height of the information of current node,the algorithm determines the termination condition of segmentation during its process,which ensures the execution efficiency and effectiveness of the algorithm.Experimental results show that this algorithm is highly effective.
