It is a format to share data, defined in the 1.0 version of XML.You can deliver information in this format et one can get this information, and information from other various sources, in this format.
The file holds one channel at least, this is the website that provides the information. These are web pages from the same site, or from other sites. This may be accomplished just by a click on an "add" button to get the URL of the RSS feed, and let it added to a list of feeds. A script in PHP or other language, builds the list each time the page is displayed by loading the RSS file and extracting the data from it. These tags are required: - title: the title of your website, may be the one in the title tag of the home page.
RSS feeds are displayed by Internet Explorer 7 and Firefox 2. The RSS feed is displayed as a list of titles (and optionally summaries). Some links to such tools are provided in resources. At start, this is just a simple text file, created with any text editor. - link: the URL of your website: example: - description: description of your website, about 200 characters, this may be the text assigned to the content attribute of the description tag, in the head section of the home page. Design a small image (88x31 for example) in a common format (gif, jpg, png) and put in into the same directory that the RSS file.
An RSS reader (or aggregator) may also be installed on the operating system (Windows, Linux, Mac OS, etc...). The "image" tag is a sub-element of the channel tag - url is the address of the image itself.
- link is the address of the page displayed when one clicks on the image.
Now, we will add a web page to display an information.
This is an "item" tag, a sub-element of channel, and this components are required: - title: the title of the article. - description: a summary of the article, about 200 characters. Put the file into your website, among other web pages. This is accomplished by adding an RSS button on the home page.A click on the button should display the XML file you have created.RSS 2.0 was defined by Dave Winer (previously worker at Userland) at Harvard University in 2002.This page is based on the Really Simple Syndication, 2.01 specification from Harvard.To get information or news provided by websites in a format computers can process. And for the provider of the content, this allows it to send news about its site.The RSS system to publish articles and news over the web is very simple: It is an XML file and the global container is the "RSS" tag for the 2.0 format. The overall structure is as that: The channel will be the same for all your RSS feeds.
