我有一个问题，我们希望你能提供帮助，现在我可以将XML DOM中的数据读取到Spinner或ListView，但我想要
怎么做？ 我的XML文件：
<?xml version="1.0" encoding="utf-8"?>
<employees>
<employee id ="1" title="Human Resources Department ">
<name>Name A</name>
<phone>0909000111</phone>
</employee>
<employee id ="1" title="Human Resources Department ">
<name>Name B</name>
<phone>0909000112</phone>
</employee>
<employee id ="2" title="Technical Department ">
<name>Name A - 2</name>
<phone>0909000222</phone>
</employee>
<employee id ="2" title="Human Resources Department ">
<name>Name B - 2</name>
<phone>0909000223</phone>
</employee>
<employee id ="3" title="Sales Office ">
<name>Name C - 1</name>
<phone>0909000333</phone>
</employee>
<employee id ="3" title="Sales Office ">
<name>Name C - 2</name>
<phone>0909000333</phone>
</employee>
</employees>
