100分求教简单问题～～～～ (100分)

我们有个软件是用来短信群发的，但是在建立用户名单时，要往里输入用户名称和手机号码
还有性别，部门，要一个一个的输入，很麻烦，所以我想写个东西让他能从ecexl中导入，
该怎么写那？希望高手指教
这个软件是用vb写的，我看到里面还有几个xml文件，里面存着以下内容：
1。treeinfo00180539.xml：
<?xml version="1.0" encoding="GB2312" ?>
- <ROOT nodeType="group">
- <group2ID nodeType="group">
<people1361ID nodeType="people" />
</group2ID>
。。。

- <group23ID nodeType="group">
<people1369ID nodeType="people" />
</group23ID>
</ROOT>
