Rss structure - part 1

[From Wikipedia]RSS is a family of Web feed formats used to publish frequently updated content such as blog entries, news headlines, and podcasts in a standardized format. An RSS document (which is called a "feed", "web feed", or "channel") contains either a summary of content from an associated web site or the full text. RSS makes it possible for people to keep up with web sites in an automated manner that can be piped into special programs or filtered displays.
When we read an RSS, the reader parses an XML files, where you can find several items, correspondents to the several titles of the feed.
Every item is structured in this way:



This structure is very simple and it can be useful in two cases:
• To read XML documents that contains RSS structure;
• To self-write RSS files, for a blog or a website.
In the part 2, we’ll talk about the heading of the XML file. My interesting for this argument is derived from a new software that I’m writing, RssC. This program read RSS by a XML file.
