PHP新闻聚合工具lilina使用的Rss解析器就是MagpieRSS。
这个东西使用起来很简单，下边是官方的一个例子：
require_once(rss_fetch.inc);
$url = $_GET['url'];
$rss = fetch_rss( $url );
echo
"
"
""Channel Title: " . $rss->channel['title'] . " ;
echo ";
foreach ($rss->items as $item) {
$href = $item['link'];
$title = $item['title'];
echo "
$title" ;
}
echo ";
