在个人建站的过程中,经常要从其他网站获取大量动态信息。
本文所描述的就是使用php程序读取rss标准的xml格式文件,动态显示他人站点的信息列表。
My CSDN Blog : perl php Perl/PHP XML::RSS读取个人CSDN博客的例子
JLinux : perl php Perl/PHP XML::RSS读取JLinux的例子
新浪新闻 综合 perl php 体育 perl php 娱乐 perl php
对于php编程爱好者来说,前期的准备相对简单,只要有php4以上的环境就可以建立此功能。
基本上很多网站提供的用来做rss浏览的文件都是以下的格式,这是符合xml的w3c通用标准的。
简单的分析一下,
基本的树结构是,
一个rss根下,有一个channel节点,
该channel节点下的title,link,description属性是常用的,
然后就是item节点,众多item节点是最近跟新的若干篇文章,
该item节点下的title,link,pubDate,description属性是常用的。
简单格式如下:
<channel>
<title>本站点频道的标题</title>
<link>链接地址</link>
<description>站点频道描述信息</description>
<item>
<title>文章1</title>
<link>文章1链接地址</link>
<description>文章1内容简介</description>
</item>
<item>
<title>文章2</title>
<link>文章2链接地址</link>
<description>文章2内容简介</description>
</item>
</channel>
</rss>

<description>很多人搞技术,还有很多转行搞技术,搞了一段时间终于发现,自己不适合作技术,要我说其实就是用脑方式的问题。真的学会适当的用脑方式,编程编起来得心应手。<img src ="http://blog.csdn.net/thefirstwind/aggbug/1440965.aspx" width = "1" height = "1" /></description>
