生成的xml內(nèi)容如下：

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

<?xml version="1.0" encoding="utf-8"?>
<people>
??? <!--將數(shù)據(jù)從程序輸出到XML中！-->
??? <person id="001" gender="male">
??????? <name>劉德華</name>
??????? <address>香港</address>
??? </person>
??? <person id="002" gender="male">
??????? <name>林志穎</name>
??????? <address>臺灣</address>
??? </person>
</people>
