Problems solved by technology
However, this approach has significant limitations
First of all, the open interfaces of videos released by various video websites are very different, which is not conducive to the development of media asset aggregation software
Secondly, if the website changes the application interface, the software must be adjusted or even rewritten to adapt to the new application interface, which is not conducive to software maintenance
Thirdly, currently there are very few domestic video websites that provide open APIs. Websites without open APIs cannot be aggregated, and are passively controlled by video websites.
In addition, at present, domestic video websites use open APIs to cooperate in an immature way, and the opening of their APIs is not comprehensive, and some even have the problem of providing wrong information, and are neglected to maintain, update slowly, and the timeliness of media information poor sex
Therefore, this method cannot meet the needs of media asset aggregation at this stage, and requires a more general, stable and easy-to-maintain method

Embodiment Construction
[0025] The present invention will be further described below with reference to the accompanying drawings and in combination with preferred embodiments.
[0026] The present invention comprises the steps:
[0027] 1. Configuration file generation:
[0028] By analyzing the HTML script source code of the video website, summarizing the structural characteristics of the DOM subtree where the media asset type needs to be extracted by the video website, inputting it to the computer, and generating different configuration files through the configuration file generation module to store the DOM subtree matching template and other information required in the aggregation algorithm. This configuration file can cooperate with the aggregation algorithm, which can be continuously modified and improved during the development stage.
[0029] The types of media assets that need to be extracted refer to different types of media assets such as video classification, video list, and video detaile...

The invention discloses a video website media asset integrating method and system based on DOM tree matching. The method includes S1, generating configuring files, namely generating configuring files, structurally comprising basic information units, media asset parameter units and DOM subtree structure units, according to user output; S2, acquiring HTML documents and generating DOM trees of the HTML documents, namely requiring websites to be integrated and acquiring HTML documents, and analyzing the HTML documents to generate DOM trees of the HTML documents; S3, extracting media assets, namely guiding in matching templates and generating template DOM trees, matching the DOM trees of the HTML documents with the template DOM trees, extracting sub-nodes with most simplified structures from the DOM trees of the HTML documents, and extracting media asset information contained in the sub-nodes. Compared with the prior art, the method has better compatibility and stability.
Description
technical field [0001] The invention relates to the field of network communication and multimedia information processing, in particular to a method and system for aggregating video website media resources based on DOM tree matching. Background technique [0002] With the rapid growth of domestic video websites and the huge amount of videos on the Internet, watching videos online has become a necessary demand in the lives of more and more people. However, there are many kinds of video websites, the distribution of video resources is scattered, and the video formats and plug-ins are different, which brings certain obstacles for users to search and watch videos. The media asset aggregation platform can aggregate information such as program classification, program information list, and video detailed information of major video websites, so that users can obtain the latest video resource information in a unified client without having to log in to video websites one by one. And w...
