关于xml的问题

[redshiliu]

Private Sub CreateGBFile()
Dim DOM As DOMDocument
Dim Node As IXMLDOMNode

If Dir(App.Path & "\GB.xml") <> "" Then Kill App.Path & "\GB.xml"
Set DOM = New DOMDocument
Set Node = DOM.createElement("GB")

DOM.appendChild Node
~~~~~~~~~~~~~~~~~~~~
CreateNode Node, "Speed"

DOM.save App.Path & "\GB.xml"
End Sub

Private Sub CreateNode(pNode As IXMLDOMNode, Name As String, Optional Value As String)
Dim Node As IXMLDOMNode

Set Node = pNode.ownerDocument.createElement(Name)
Node.Text = Value
pNode.appendChild Node
End Sub

我的疑问是DOM.appendChild Node这句无论放在CreateNode前还是后，得到的结果都一样，为什么？

DOM.appendChild，應該說是記錄 NODE的地址，在此之前，NODE已經建立，地址已經知道。
