Selecting nodes in xml, and comparing them to a directory

I know this has been asked many times before but i believe my situation is slightly different because of my node names, and sadly, they must remain, i cannot change them.

so, my issue is that I writing a program to check a directory and its subfolders (not files) against an xml tree. I have already implemented the reverse of checking the xml against the directory for missing folders, now i want to check for extra folders that arent part of the xml tree, and in order to do so i guessed that the selectsinglenode() would be the best way to go about it.

so my xml file looks like so....

Code:

---

<?xml version="1.0"?>
<XMLTreeView>
  <Node name='.Drawing' />
  <Node name=".Paint">
    <Node name="EDR" />
    <Node name="FDM" />
    <Node name="ERG" />
    <Node name="FTL" />
    <Node name="MRG" />
    <Node name="MOR" />
  </Node>
  <Node name=".Materials" />
  <Node name=".WS" />
  <Node name=".SJI" />
</XMLTreeView>

and heres what i have so far...

Code:

---

    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        TextBox1.Clear()

        TextBox1.Text += " Folders not in indexed structure:" + ControlChars.NewLine + ControlChars.NewLine
        For Each Dir As String In Directory.GetDirectories("C:\Users\Aaron\Documents\KTDStruct")
            For Each Dir2 As String In Directory.GetDirectories(Dir)
                CheckFolderAgainstIndex("C:\Users\Aaron\Documents\struct1.xml", Dir2)
            Next
        Next
    End Sub

    Private Sub CheckFolderAgainstIndex(ByVal XMLFilepath As String, dir As String)
        Dim XMLDoc As New Xml.XmlDocument
        Dim XMLNode As Xml.XmlNode
        Dim folderName As String
        Try
            XMLDoc.Load(XMLFilepath)
        Catch e As Exception
            Throw New Exception(e.Message)
        End Try
        Dim subfolders() As String = Directory.GetDirectories(dir)
        For Each folder In subfolders
            folderName = folder.Split("\").Last
            Try
                XMLNode = XMLDoc.SelectSingleNode(folderName)
                If XMLNode Is Nothing Then
                    TextBox1.Text += dir + "\" + folderName + ControlChars.NewLine
                End If
            Catch
                    TextBox1.Text += "error: " + dir + "\" + folderName + ControlChars.NewLine
            End Try

        Next
    End Sub

the following is what comes out on textbox1:

Code:

---

Folders not in indexed structure:

error: C:\Users\Aaron\Documents\KTD\PersonABC\1234\.Drawing
error: C:\Users\Aaron\Documents\KTD\PersonABC\1234\.Paint
error: C:\Users\Aaron\Documents\KTD\PersonABC\1234\.QS
error: C:\Users\Aaron\Documents\KTD\PersonABC\1234\.SJI
C:\Users\Aaron\Documents\KTD\PersonABC\1234\faadfjadf

---

i added in the "faadfjadf" folder into the structure at random so that it would catch it, and it does, however...

if i change the .paint folder to just paint, and in the xml file as well, it doesnt report the error, but still says that the xml file doesnt have a node called paint :(

im just confused, im not worried about the subfolders at the moment, thats just a little recursion later.

heck, maybe im going about this all wrong anyways and someone has a better idea on comparing an xml to a directory structure
