Abstract

The invention provides a webpage main body information extraction method and device and a storage medium, and the method comprises the steps: webpage source code obtaining: receiving webpage address information, and obtaining the webpage source code of a webpage in the Internet according to the webpage address information, wherein the webpage source code comprises at least one node, and the node comprises at least one label; and main body information extraction: traversing each node in the webpage source code, judging whether the information of the node is main body information or not according to the label in the node, and if so, extracting the information in the node as the main body information. Firstly, a webpage is found in the Internet through webpage address information, a main bodypart in the webpage is recognized by processing a webpage source code, and when a user browses the webpage, information of the main body part can be directly browsed, so that on one hand, network resources occupied by useless information of a non-main body part are reduced, and the utilization rate of Internet resources is increased; on the other hand, the information acquisition efficiency of users is improved.
