I can see that there are RSS in many places. When I look for some technical articles in the search engine, I often find places like blog.csdn.net/xxx and xxx.blogchina.com. These locations look like personal websites, but they are a little different. I can't help wondering what RSS is. So I opened the baidu search engine to search for RSS.
After reading a lot of places, I gradually understood something. RSS seems to be associated with the blog. RSS allows many websites to share a protocol for website articles. The blog is said to be short for web log, which means "web log. People often record some of their experiences and use them to share their experiences with others.
RSS's website sharing mechanism (technology) uses XML for data exchange. It is said that there are several versions of RSS, and these protocols are not compatible yet.
To experience the blog, I registered my personal blog at blog.csdn.net and blogchina.com respectively. Then I checked the XML structure of the RSS of the two websites, and found that the difference was great. I guess RSS does not clearly define the standards for data exchange in website articles.
This RSS sharing mechanism gives me an idea to share information between different websites (or share data in different places on the same website) and exchange data with XML, then, use your own XSL to interpret XML, and the website style will be consistent, so that the article is exactly the same as the one entered and generated on your website. This is a good way to share data.
Of course, there are some intermediate steps to achieve data sharing. First, how do I obtain data by taking the initiative to fetch data from other websites, or do I subscribe to the data from the other website and send it to the other website? The second is how to add data to your own database. Because the data comes from different websites, some websites with high requirements for sorting the document list must sort and filter the data from different websites. Finally, data can be sorted and approved before a list of articles can be generated.
In RSS, there is a mechanism called "reference", also known as "Aggregation" (trackback in English), which is used to provide network sharing. However, I have not found any information about how to use this mechanism. (Because I don't know how to use this mechanism, I have to input each article on both websites when I update the article)
Below are some articles I have seen to illustrate the blog:
