用DOM解析XML时出现了如下错误：
[Fatal Error] :3:13: Open quote is expected for attribute "{1}" associated with an element type "id".
org.xml.sax.SAXParseException: Open quote is expected for attribute "{1}" associated with an element type "id".

检查后发现我的xml文件是这样写的
<?xml version="1.0" encoding="UTF-8"?>
<message>
<person id=1>
<name>jerry</name>
<age>18</age>
<sex>男</sex>
</person>
<person id=2>
<name>Aimi</name>
<age>20</age>
<sex>女</sex>
</person>
</message>
错误就在于，xml元素的开始标签的属性必须用双引号括起来
改为：
<person >
<person >
