Embodiment

[0058] Such as figure 2 , 3 As shown, the automatic monitoring of the update of the "Netease Technology-Entrepreneurship Club" column is used as the application scenario introduced in the specific implementation of the present invention.

[0059] (1) Assume that user A needs to pay attention to the update of the "Netease Technology-Venture Club" column. The user enters the corresponding URL http: / / tech.163.com / chuang / in the destination URL input box of the application;

[0060] (2) The application sends the target URL to the rendering server, the rendering engine renders the target URL, and returns the rendered result to the application, and the application displays the rendered webpage to the user;

[0061] (3) The user drags and selects the content corresponding to "Daily Featured" as his focus. The application can obtain the filter expression corresponding to the "Daily Featured" selected by the user as XPath: / / *[ id="mrjx"] / div[2]. The user can modify the filter expression by...

Abstract

The invention discloses a filtering expression and rendering engine based method for automatically monitoring update of a dynamic webpage. A user appoints an interested part in the webpage as a concerned point through a visualized interface, and an application or a client automatically generates a filtering expression corresponding to the concerned point; a server renders the dynamic webpage by utilizing the rendering engine to obtain the same page seen by the user, and extracts the concerned point of the user; and when the concerned point of the user is updated, the server pushes the update content to the user in time. According to the method, a customizable dynamic webpage monitoring program is realized by helping the user appoint the concerned point and utilize the rendering engine for automatically inspecting webpage update at the server, the problem of lack of customization for a conventional information subscription mode (such as RSS (really simple syndication)) is solved, the defect of incapability of analyzing the dynamic webpage in conventional webpage capture is also overcome, and the efficiency for obtaining webpage information update by the user is improved.

Description

Technical field [0001] The invention belongs to the computer field, and particularly relates to a method for automatically monitoring dynamic webpage updates. Background technique [0002] With the rapid development of the Internet, the Internet has gradually replaced traditional media and has become the main channel for people to obtain information. However, since most web pages do not provide an active notification function when information is updated, people's efficiency in obtaining information from web pages is not high. In order to follow multiple web pages, people can only manually open each web page that needs to be followed and manually filter new information. And for some websites with low update frequency, people open it again and again and find that there is no update, wasting a lot of time. The process of people obtaining information on webpages has disadvantages such as poor flexibility and poor timeliness. [0003] In order to improve the efficiency of obtaining i...
