[bold]Filtering a Treeview[/bold]

[Orion45]

I am trying to build a menu using a treeview control populated by an XML file. This XML is divided into several sections since the same xml is used throughout the application. It is indexed by Area, Application, and Page. I need a way to filter the treeview to only display nodes that are specific to the page I am currently on. I am new to .net and do not know the syntax for doing this. My code currently displays everything in the xml file. Any advice on this is appreciated. Thanks,

 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Try
            Dim dom As New XmlDocument()
            dom.Load(TextBox1.Text)

            TreeView1.Nodes.Clear()
            TreeView1.Nodes.Add(New TreeNode(dom.DocumentElement.Name))
            Dim tNode As New TreeNode()
            tNode = TreeView1.Nodes(0)

            AddNode(dom.DocumentElement, tNode)
            TreeView1.ExpandAll()
        Catch xmlEx As XmlException
            MessageBox.Show(xmlEx.Message)
        Catch ex As Exception
            MessageBox.Show(ex.Message)
        End Try

    End Sub

    Private Sub AddNode(ByRef inXmlNode As XmlNode, ByRef inTreeNode As TreeNode)
        Dim xNode As XmlNode
        Dim tNode As TreeNode
        Dim Parent As XmlNode
        Dim nodeList As XmlNodeList
        Dim i As Long

        If inXmlNode.HasChildNodes() Then
            nodeList = inXmlNode.ChildNodes
            For i = 0 To nodeList.Count - 1
                xNode = inXmlNode.ChildNodes(i)
                inTreeNode.Nodes.Add(New TreeNode(xNode.Name))
                tNode = inTreeNode.Nodes(i)
                AddNode(xNode, tNode)
            Next
        Else
            inTreeNode.Text = (inXmlNode.OuterXml).Trim
        End If
    End Sub
