Looking for a more elegant way to assign XML node values to an array

Really, I just can't believe that I constantly get the "Can't assign to array" error message... :(
I can read an XML file easily and assign the node values to a collection but the same is not true for an array. I don't know why, I guess I need to read more about Collection vs Array differences but anyway...
I finally came up with a 'dirty' alternative solution using an intermediary variant variable (vID). The code below works OK but... is it somehow possible to do this more elegantly, e.g. without a variant variable (no collections please)?!

Rich (BB code):
Sub ParseXML(sFileName As String)
'Trying to assign XML node values to an array cuz I hate Collections... sometimes!

    Dim xFile As MSXML2.DOMDocument
    Dim xNode As MSXML2.IXMLDOMNode
    Dim xNodes As MSXML2.IXMLDOMNodeList
    Dim vID
    Dim NumberOfNodes As Integer
    Dim i As Integer
    Dim aTemp() As String

    Set xFile = New MSXML2.DOMDocument
    
    xFile.async = False
    xFile.Load (sFileName)
    
    'Start reading XML nodes
    If Not xFile.SelectNodes("//NamedNode") Is Nothing Then
        Set xNodes = xFile.SelectNodes("//NamedNode")
        
        NumberOfNodes = xNodes.Length
        ReDim Preserve aTemp(NumberOfNodes - 1)   'Preparing array for the loop
        
        'This loop is important:
        'i) XML node values are assigned to an intermediary variant vID, then
        'ii) values of vID are assigned to array aTemp()
        For Each xNode In xNodes
            vID = xNode.Attributes.getNamedItem("id").Text
            aTemp(i) = vID
            i = i + 1
        Next
    Else
        Debug.Print "No such nodes..."
    End If
    
    Set xFile = Nothing
'Stop
End Sub

Thanks!

How to create a cell-sized chart?
Tiny charts, called Sparklines, were added to Excel 2010. Look for Sparklines on the Insert tab.
Please test this, it works for me:

Code:
Sub ParseXML(sFileName$)
Dim xFile As MSXML2.DOMDocument60, xNode As MSXML2.IXMLDOMNode, xNodes As MSXML2.IXMLDOMNodeList, _
i%, aTemp$(), child As MSXML2.IXMLDOMNode, s$
Set xFile = New MSXML2.DOMDocument60
xFile.async = False
xFile.Load (sFileName)
If Not xFile.SelectNodes("//bookstore") Is Nothing Then     ' your node name here
    Set xNodes = xFile.SelectNodes("//bookstore")
    i = 0
    For Each xNode In xNodes
        For Each child In xNode.ChildNodes
            ReDim Preserve aTemp(i)
            aTemp(i) = child.nodeName & ":" & child.Text
            s = s & aTemp(i) & vbLf
            i = i + 1
        Next
    Next
Else
    MsgBox "No such nodes..."
End If
Set xFile = Nothing
MsgBox s
End Sub
