Second: RSS file structure

----------------------

The following is an example of RSS2.0 to illustrate that the core of an RSS file is an XML file, so you must first conform to the XML Schema format.

It is to

<rss version= "2.0" >...</rss>

This form of root format.

RSS has a <channel> child node, which contains the contents of the file, in <channel>, there are several elements to describe the information. There are detailed content on the site Http://backend.userland.com/rss, For example, the following:

Title: Headlines, often with sources of information

URL address of the Link:web site

Description: A simple description of the site.

Each piece of information is represented by a <item> element, it is included in the <channel> node, each <channel> can have multiple <item>, and each <item> node is the true node information:

Title: Titles of list items

Link: The Weburl address of the list item,

Description: A brief description of the list item,

Author: author of list information

pubdate: Release time.

I'll put an example here (information is for reference only):

<rss version="2.0">
<channel>
<title>编程入门网</title>
<link>http://www.bianceng.cn</link>
<description>编程入门网</description>
<item>
<title>有话说</title>
<link>http://www.bianceng.cn</link>
<pubDate>Sun, 14 Dec 2006 21:00:00 GMT</pubDate>
</item>
</channel>
</rss>

Here, one of the most important nodes is the pubdate format, which must conform to the RFC822 criteria and see the details. Starts with a three-letter-length week, then the number of days in the month, then the 3-letter month, then the year, then the specific time, and then the time zone.

For more information, please check the information and I'll give you a brief introduction.
