$xmldoc = new DOMDocument('1.0', 'UTF-8');
$xmldoc->load('datas.xml');
$itemsNodeList = $xmldoc->getElementsbyTagName('学生');
$itemElement = $itemsNodeList->item(0);//得到第一个完整的学生信息节点
$itemChildsNodeList = $itemElement->getElementsbyTagName('名字');//得到子节点“名字”,也许有多个名字
$itemChildNode = $itemChildsNodeList->item(0);//得到第一个名字节点
echo $itemChildNode->nodeValue;//输出节点值
//封装成函数
$nodeArr = array('名字', '年龄', '介绍');

$items = $xmldoc->getElementsByTagName($itemsName);
for($i=0; $i < $items->length; $i++){
