Abstract

The invention provides an adaptive method and apparatus for automatic regression detection and block matching of web page change, which can dynamically detect the change of target web page and give modification suggestions. The adaptive method for automatic regression detection of web page changes and block matching is characterized in that the adaptive method comprises the following steps: detecting web page changes, detecting whether web pages of a new and an old target system are changed and providing a report; carrying out Content block matching. After receiving the report of detecting thechange, the web page is analyzed to find out the content block part corresponding to the web page of the new target system and the web page of the old target system. The content block matching includes the following steps: character analyzing step, obtaining the semantic information and the character area; A graphical interface analysis step of obtaining a graphical area; The mapping step performs similarity matching on the semantic information, the text area and the graphic area obtained above, and then, based on the change of the corresponding content block part, gives the code modificationsuggestions for the existing web page data extraction system tools.

Description

technical field [0001] The invention relates to the technical field of webpage data extraction, in particular to an adaptive method and device for automatic regression detection and block matching of webpage changes. Background technique [0002] With the development of Web technology and the arrival of the era of big data, the webpage system began to contain more and more information, which led to the development of various technologies for extracting data (information carriers) from the webpage system. To extract the data from the webpage, it is first necessary to locate the data needed in the webpage. Common positioning techniques for elements in the webpage include positioning based on XPath (XML Path Language, XML Path Language), based on CSS (Cascading StyleSheets, Cascading style sheet) selector positioning, and other simple positioning based on id attributes, name attributes, etc. These positioning technologies are very dependent on the structure of the webpage. Aft...
