調(diào)用程序如下:

Option Explicit

 

Private Sub Form_Load()

    Dim obj As New ClsXml

    obj.xml = "<action name=""login""><username>a</username><password>1</password></action>"

    MsgBox obj.getNodeAttribute("name")

    MsgBox obj.getNodeValue("username")

    MsgBox obj.getNodeValue("password")

    obj.createDocument "logout"

    obj.appendNode "username", "a"

    obj.appendNode "password", "1"

    MsgBox obj.xml

    Unload Me

End Sub
