Loading and Retrieving the Contents of an XML File

 
          
Sub ReadXMLDoc() 
    Dim xmldoc As MSXML2.DOMDocument50 
    Set xmldoc = New MSXML2.DOMDocument50 
    xmldoc.async = False 
    If xmldoc.Load("C:\yourFile.xml") Then 
        Debug.Print xmldoc.XML 
        Debug.Print xmldoc.Text 
    End If 
End Sub



Retrieving Information from Element Nodes

 
Sub IterateThruElements() 
    Dim xmldoc As MSXML2.DOMDocument50

            Debug.Print xmlNode.nodeName & "=" & xmlNode.Text 
          End If

Retrieving Specific Information from Element Nodes

Retrieving the First Matching Node

 
Sub SelectSingleNode() 
    Dim xmldoc As MSXML2.DOMDocument50

    Set xmldoc = New MSXML2.DOMDocument50 
    xmldoc.async = False 
    xmldoc.Load ("C:\yourFile.xml") 
    Set xmlSingleNode = xmldoc.SelectSingleNode("//Name") 
    If xmlSingleNode Is Nothing Then 
        Debug.Print "No nodes selected." 
    Else 
        Debug.Print xmlSingleNode.Text 
    End If 
    Set xmlDoc = Nothing 
End Sub



Working with XML Document Nodes

    If xmldoc.hasChildNodes Then 
        Debug.Print "Number of child Nodes: " & xmldoc.childNodes.length 
        For Each xmlNode In xmldoc.childNodes 
            Debug.Print "Node name:" & xmlNode.nodeName 
            Debug.Print "Type:" & xmlNode.nodeTypeString & "(" & xmlNode.nodeType & ")" 
            Debug.Print "Text: " & xmlNode.Text 
        Next xmlNode 
    End If
