生成的xml内容如下：

----------------------------------------------------------------------------------------------------------------------------

 1 <?xml version="1.0" encoding="utf-8"?>
 2 <people>
 3     <!--将数据从程序输出到XML中！-->
 4     <person id="001" gender="male">
 5         <name>刘德华</name>
 6         <address>香港</address>
 7     </person>
 8     <person id="002" gender="male">
 9         <name>林志颖</name>
10         <address>台湾</address>
11     </person>
12 </people>
