' 为了使这对人类更具可读性，我们需要添加格式、缩进并添加一个 children 之前的马车 return。然后递归地使用增加的缩进格式化 children。

Sub FormatXmlNode(ByVal node As IXMLDOMNode, ByVal indent As Integer)
    Dim child As IXMLDOMNode
    Dim text_only As Boolean

    ' Do nothing if this is a text node.
    If TypeOf node Is IXMLDOMText Then Exit Sub

    ' See if this node contains only text.
    text_only = True
    If node.HasChildNodes Then
        For Each child In node.ChildNodes
            If Not (TypeOf child Is IXMLDOMText) Then
                text_only = False
                Exit For
            End If
        Next child
    End If

    ' Process child nodes.
    If node.HasChildNodes Then

        ' Add a carriage return before the children.
        If Not text_only Then
            node.InsertBefore node.OwnerDocument.createTextNode(Chr(10)), node.FirstChild
        End If

        ' Format the children.
        For Each child In node.ChildNodes
            FormatXmlNode child, indent + 2
        Next child
    End If

    ' Format this element.
    If indent > 0 Then

        ' Indent before this element.
        node.ParentNode.InsertBefore node.OwnerDocument.createTextNode(Space$(indent)), node

        ' Indent after the last child node.
        If Not text_only Then node.appendChild node.OwnerDocument.createTextNode(Space$(indent))

        ' Add a carriage return after this node.
        If node.NextSibling Is Nothing Then
            node.ParentNode.appendChild node.OwnerDocument.createTextNode(Chr(10))
        Else
            node.ParentNode.InsertBefore node.OwnerDocument.createTextNode(Chr(10)), node.NextSibling
        End If
    End If
End Sub

' 将 XML 数据保存到磁盘。

On Error Resume Next
MkDir ("C:\Users\" & Environ$("Username") & _
"\Desktop\FXML_FILES") 'Creates folder on desktop, ignores error if it already exists
On Error GoTo 0

objDom.Save ("C:\Users\" & Environ$("Username") & _
"\Desktop\XML_FILES\" & "filename.xml")
