我想用PHP解析Google News rss。我设法运行这段代码:
<?
$news = simplexml_load_file('http://news.google.com/news?pz=1&cf=all&ned=us&hl=en&topic=n&output=rss');
foreach($news->channel->item as $item) {
echo "<strong>" . $item->title . "</strong><br />";
echo strip_tags($item->description) ."<br /><br />";
}
?>
但是,我无法解决以下问题。例如:
感谢。

我们去了,只是你需要的特殊情况:
<?php
$news = simplexml_load_file('http://news.google.com/news?pz=1&cf=all&ned=us&hl=en&topic=n&output=rss');
$feeds = array();
$i = 0;
foreach ($news->channel->item as $item)
{
preg_match('@src="([^"]+)"@', $item->description, $match);
$parts = explode('<font size="-1">', $item->description);
$feeds[$i]['title'] = (string) $item->title;
$feeds[$i]['link'] = (string) $item->link;
$feeds[$i]['image'] = $match[1];
$feeds[$i]['site_title'] = strip_tags($parts[1]);
$feeds[$i]['story'] = strip_tags($parts[2]);
$i++;
}
echo '<pre>';
print_r($feeds);
echo '</pre>';
?>
输出应如下所示:
[2] => Array

我建议您查看SimplePie。我已经将它用于几个不同的项目,并且效果很好(并且抽象出了你目前正在处理的所有头痛)。
现在,如果您只是因为想要学习如何编写此代码,那么您应该忽略这个答案。 :)
