PHP利用RSS订阅别处文章
这篇文章是接上篇利用PHP操作XML文件的。RSS是基于XML的一种形式,它的具体规范如下(我们以截取的新浪RSS订阅频道的格式来看):
输入:http://rss.sina.com.cn/news/world/focus15.xml 查看页面源码就可以看到RSS的结构:
http://news.sina.com.cn/world
http://news.sina.com.cn/491/2008/0827/1.html

虽然这次投票在法律上不具备约束力,但是人权活动分子说,每两年举行一次的表决,是向那些依然保留死刑的国家发出的强烈信号,这些数量在逐步减少的国家....]]>
具体规范信息是代表什么意思,根据标签的内容我们就可以很容易的知道,下面我们写一个rss.php来读取这个xml,从而获取这上面的文章:
$dom = simplexml_load_file("http://rss.sina.com.cn/news/world/focus15.xml");
//var_dump($dom);
?>
The example of RSS
- ");
print("");
print($item->title);
print("");
print(" ");
foreach($dom->channel->item as $item)
{
print("
}
?>
注意这个函数:simplexml_load_file() ; 它既可以读本地的xml文件,也可以读网络上的xml。
运行结果:
