DOMDocument对象遍历输出假日数据：

<?php

//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($yearsas $year){

   

    //获得具体的年份值

    $yearNames = $year->getElementsByTagName("yearName");

    $yearName =$yearNames->item(0)->nodeValue;

    echo $yearName.'年'.'</br>';

   

    //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).': '.'</br>';

       

        //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.'</br>';

       

        //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 '</br>';

        }

        echo '</br>';

    }

}

?>
