okay I am building acustom nav provider and based on some custom logic i need to remove nodes from the menu

The code I am using is very basic but having problems whan I remove a node - the last 4 lines are where i remove a node but if i remove a node then it seems to skip processing the next in line - in other words is shows it even if it is not supposed to be shown - now I see why but nbot sure how I am supposed to fix it - the current node is removed so it doesnt seem to understand where it is in the node collection  - how do I fix or revise doing this

                     For Each objNode In objNodes
                        Dim myTest As Boolean = False
                        For Each ATabID As Integer In MyListAppTabs
                            If ATabID = Convert.ToInt32(objNode.ID) Then
                                myTest = True
                            End If
                        Next
                        If myTest = False Then
                            objNodes.Remove(objNode)
                        End If
                    Next

yeah tried that now and i am still getting errors

I added the nodes i want to a new dnn nodes collection but i lost all teh hieararchy why would that happen?

sorry more info

so for example I have a user admin area open to certain roles

Admin

          User Admin

          Location Admin

It now appears as a straight line

Admin        User Admin        Location Admin
