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
<?xml version="1.0" encoding="UTF-8"?>
<daysOff-overTime>
<year>
<yearName>2012</yearName>
<holiday>
<holidayName>元旦</holidayName>
<daysOff>
<from>2012-1-1</from>
<to>2012-1-3</to>
</daysOff>
<overTime>
<day>2011-12-31</day>
</overTime>
</holiday>
<holiday>
<holidayName>春节</holidayName>
<daysOff>
<from>2012-1-22</from>
<to>2012-1-28</to>
</daysOff>
<overTime>
<day>2012-1-21</day>
<day>2012-1-29</day>
</overTime>
</holiday>
<holiday>
<holidayName>清明节</holidayName>
<daysOff>
<from>2012-4-2</from>
<to>2012-4-4</to>
</daysOff>
<overTime>
<day>2012-3-31</day>
<day>2012-4-1</day>
</overTime>
</holiday>
<holiday>
<holidayName>劳动节</holidayName>
<daysOff>
<from>2012-4-29</from>
<to>2012-5-1</to>
</daysOff>
<overTime>
<day>2012-4-28</day>
</overTime>
</holiday>
<holiday>
<holidayName>端午节</holidayName>
<daysOff>
<from>2012-6-22</from>
<to>2012-6-24</to>
</daysOff>
<overTime/>
</holiday>
<holiday>
<holidayName>中秋节、国庆节</holidayName>
<daysOff>
<from>2012-9-30</from>
<to>2012-10-7</to>
</daysOff>
<overTime>
<day>2012-9-26</day>
</overTime>
</holiday>
</year>
</daysOff-overTime>
