PHP通过DOM解析XML文件或者xml字符串
上一篇记录了php创建xml文档的过程，这篇将记录如何把接受到的xml字符串中的数据和属性值解析出来，以便进一步对数据进行处理。
xml文件
1. <?xml version="1.0" encoding="utf-8"?>
2. <data>
3. <time value="2011-08-01"/>
4. <time value="2011-08-02"/>
5. <time value="2011-08-03">
6. <worker name="test1" id="14">

8. <hour pid="6" pmid="3"><![CDATA[spot411]]></hour>
9. </worker>
10. </time>
11. <time value="2011-08-04">
