小妹又遇到取XML子节点问题。请帮忙给看看1
我取到一级目录的节点,但是它的下一级目录我就是取不到

不知道为什么请各位师哥指正。
$XMLStr='

 
 
 
 
 

 
 
 
 

 

';
if($XMLStr!="")
{
$XMLStr=stripcslashes($XMLStr);
$xml = new DOMDocument(); //建立一个DOMDocument
$xml->loadXML($XMLStr); //Php指定需要读取xml文件的位置
$itemObj = $xml->getElementsByTagName('WallPaper');//按照名称取得节点,返回所有节点的集合,不过这里这样读LevelOne是没有意义的....

for($i=0;$ilength;$i++)
{  
$id= $itemObj->item($i)->getAttribute("ID");
$updatetime= $itemObj->item($i)->getAttribute("UpdateTime");
echo "ID:".$id."
";
echo "UpdateTime:".$updatetime."
";//到这里都正确!

$PointObj=$itemObj->getElementsByTagName('Point');//再去查找一下子节点
echo $PointObj->length;
}
}
?>

总报错:Fatal error: Call to undefined method DOMNodeList::getElementsByTagName() in C:\wamp\www\admin\interface\wallpaper_update.php on line 36

帮我看看这是为什么那!请师哥指正。
