=============以下是可参考vb代码===================
Private Sub Command1_Click()
    On Error Resume Next
    Dim blnBLoad As Boolean
    Dim i As Integer
    Dim j As Long
    Dim k As Long
    Set Xml = New DOMDocument
    bLoad = Xml.Load(App.Path & "\chinese.xml")
    If bLoad = False Then
        MsgBox "Error"
        Exit Sub
    End If

    Dim root As IXMLDOMElement
    Set root = Xml.documentElement

    Dim node As IXMLDOMNode
    Dim sec_node As IXMLDOMNode
    Dim thr_node As IXMLDOMNode
    Dim fro_node As IXMLDOMNode
    For Each node In root.childNodes

        Text1.Text = Text1.Text & "国家:" & node.Attributes.getNamedItem("Name").Text & vbCrLf
        For Each sec_node In node.childNodes
            If sec_node.nodeName = "State" Then
                Text2.Text = Text2.Text & "州/省:" & sec_node.Attributes.getNamedItem("Name").Text & vbCrLf
                For Each thr_node In node.childNodes
                    Text3.Text = Text3.Text & "城市:" & thr_node.Attributes.getNamedItem("Name").Text & vbCrLf
                Next
            Else
            End If
        Next
    Next
End Sub


做成三个Combo的联动效果。

以上是附件 Chinese.xml 文件。

我想用vb做成和QQ注册（http://reg.）号码时中“所在地”一样的效果。
可以达到这样的效果吗？

有人测试吗？
