php读取网页文件的有关问题

php读取网页文件的问题
我想读取一个网页的一些数据，网址是：http://www.xjflcp.com/servlet/sscflash?type=full&rand=2266

我的代码是这样的：

$url="http://www.xjflcp.com/servlet/sscflash?type=full&rand=2266";

		$doc = new DOMDocument();
		$doc->load($url); //读取xml文件
	//	$datas= $doc->saveXML();
//		$lst = $doc->getElementsByTagName('history1');
//		$t1 = $lst->item(0)->getElementsByTagName("draw")->item(0)->nodeValue; //取得name的标签的对象数组 
//		$t1 = substr($t1,2,6)."0".substr($t1,-2);
//		$t2 = $lst->item(0)->getElementsByTagName("prize_number")->item(0)->nodeValue; //取得name的标签的对象数组 
//		$t2 = str_replace("|",",",$t2);	
		
		
		$lst = $doc->getElementsByTagName('row');
	//    for ($i=0; $i<$lst->length; $i++) {
		for ($i=0; $i<2; $i++) {
			$iframe= $lst->item($i);
			$t1=$iframe->attributes->getNamedItem('draw')->value;
			$t2=$iframe->attributes->getNamedItem('prize_number')->value;

想获取第二行

<recent_draw>
<draw>2014082856</draw>
<prize_number>1|4|0|9|5</prize_number>
<sale_count>57446</sale_count>
<prize_levels>23</prize_levels>>

draw、prize_number请问应该怎么改
------解决方案--------------------

$url="http://www.xjflcp.com/servlet/sscflash?type=full&rand=2266";
$doc = new DOMDocument();
$doc->load($url);

$recent_draws=$doc->getElementsByTagName("recent_draw");

$recent_draw=$recent_draws->item(0);
$draw=getNodeVal($recent_draw,"draw");
$prize_number=getNodeVal($recent_draw,"prize_number");

echo $draw.'<br>';
echo $prize_number.'<br>';
function getNodeVal(&$myNode,$tagName){
	return $myNode->getElementsByTagName($tagName)->item(0)->nodeValue;
}
