How to open xls file. Implementation code for using DOM class to read XML file in php

主要功能：php中使用DOM类读取XML文件
设计知识点：
1、XML节点循环读取
2、用iconv()函数实现编码转换，防止中文乱码
holiday.xml文件如下

复制代码 代码如下:

复制代码 代码如下:

//读取xml文件
$xmlDoc = new DOMDocument();
$xmlDoc->load('http://127.0.0.1/holiday.xml');
//获得该xml文件中的所有年份
$years = $xmlDoc->getElementsByTagName("year");
//对每一个年份进行处理
foreach($years as $year){
//获得具体的年份值
$yearNames = $year->getElementsByTagName("yearName");
$yearName = $yearNames->item(0)->nodeValue;
echo $yearName.'年'.'
';
//获得该年份下所有的假日
$holidays = $year->getElementsByTagName("holiday");
//对每一个假日进行处理
foreach($holidays as $holiday){
//获得假日名称
$holidayNames = $holiday->getElementsByTagName("holidayName");
$holidayName = $holidayNames->item(0)->nodeValue;
echo iconv('utf-8','gb2312', $holidayName).': '.'
';
//获得假日的具体放假日期
$daysOffs = $holiday->getElementsByTagName("daysOff");
$daysOff = $daysOffs->item(0);
$froms = $daysOff->getElementsByTagName("from");
$from = $froms->item(0)->nodeValue;
$tos = $daysOff->getElementsByTagName("to");
$to = $tos->item(0)->nodeValue;
echo '假期为：'.$from.' 至 '.$to.'
';
//获得针对该假日的调休日期
$overTimes = $holiday->getElementsByTagName("overTime");
$overTime = $overTimes->item(0);
$days = $overTime->getElementsByTagName("day");
//通过判断，有调休日期则显示，没有则不显示
if($days->length!=0){
echo '调休日为：';
foreach($days as $day){
echo $day->nodeValue.' ';
}
echo '
';
}
echo '
';
}
}
?>
