Simple RSS reader

RSS (relly Simple Syndication) is a format used to describe and synchronize website content. It is currently the most widely used XML application. RSS builds a platform for rapid dissemination of information, which enables everyone to become a potential information provider. After an RSS file is published, the information contained in this RSS feed can be directly called by other sites, and because the data is in a standard XML format, it can also be used by other terminals and servers.
