正则表达式

以前写的一段正则抓取安居客经纪人信息的表达式,但是不确定现在还有么有用了！

		$url="http://shanghai.anjuke.com/brokerinfo.php?bid={$i}";
		
		$content= file_get_contents($url);
		//preg_match_all ('/
(.*)[^<]/i', $content, $matches);
		//preg_match_all('/]*>[\s]*([A-Z\s]*)?[\s]*<\/div>/', $content, $name);
		//preg_match_all ('/

		preg_match_all ('/
姓　　名：]*)>([^\x00-\x80])?[^<]*/', $content, $name);
