The code is as follows:

// Read the xml file
$ XmlDoc = new DOMDocument ();
$ XmlDoc-> load ('http: // 127.0.0.1/holiday. XML ');
// Obtain all the years in the xml file
$ Years = $ xmlDoc-> getElementsByTagName ("year ");
// Process each year
Foreach ($ years as $ year ){
// Obtain the specific year value
$ YearNames = $ year-> getElementsByTagName ("yearName ");
$ YearName = $ yearNames-> item (0)-> nodeValue;
Echo $ yearName. 'year '.'
';
// Obtain all holidays of the year
$ Holidays = $ year-> getElementsByTagName ("holiday ");
// Process every holiday
Foreach ($ holidays as $ holiday ){
// Obtain the holiday name
$ HolidayNames = $ holiday-> getElementsByTagName ("holidayName ");
$ HolidayName = $ holidayNames-> item (0)-> nodeValue;
Echo iconv ('utf-8', 'gb2312', $ holidayName ).':'.'
';
// Obtain the specific holiday date
$ DaysOffs = $ holiday-> getElementsByTagName ("daysOff ");
$ DaysOff = $ daysOffs-> item (0 );
$ Froms = $ daysOff-> getElementsByTagName ("from ");
$ From = $ froms-> item (0)-> nodeValue;
$ Tos = $ daysOff-> getElementsByTagName ("");
$ To = $ tos-> item (0)-> nodeValue;
Echo 'holiday: '. $ from.' to '. $ .'
';
// Obtain the vacation date for this holiday
$ OverTimes = $ holiday-> getElementsByTagName ("overTime ");
$ OverTime = $ overTimes-> item (0 );
$ Days = $ overTime-> getElementsByTagName ("day ");
// After judgment, if there is a period of rest, it is displayed. if not, it is not displayed.
If ($ days-> length! = 0 ){
Echo 'Day of suspension :';
Foreach ($ days as $ day ){
Echo $ day-> nodeValue .'';
}
Echo'
';
}
Echo'
';
}
}
?>

Output:
