It looks like you made good progress. Here is a version that will look for the occurrence in each view of the sheet and expand if found, I added an error catch as there is some exceptions found.
Sub Main()
'//// GET THE OCCURRENCE NAME TO FIND THE NODE ////
Dim oOccName As String = "1237-M-001:1"
Dim oDrawDoc As DrawingDocument = ThisApplication.ActiveDocument
Dim oBP As BrowserPane = oDrawDoc.BrowserPanes.Item("Model")
oBP.Activate
Dim oTNode As BrowserNode = oBP.TopNode
Dim objColl As ObjectCollection = ThisApplication.TransientObjects.CreateObjectCollection
Dim oSheet As Sheet = ThisApplication.ActiveDocument.ActiveSheet
Dim oCount As Integer = 0
On Error Resume Next
For Each oView As DrawingView In oSheet.DrawingViews
'Get the browser node definition of the drawing view
Dim oNativeBrowserNodeDef As NativeBrowserNodeDefinition
Dim oViewNode As BrowserNode
'Use the try statement or On Error as a child view will not be a Native Browser Definition,
'it will be picked up By the recursion Loop later
oNativeBrowserNodeDef = oDrawDoc.BrowserPanes.GetNativeBrowserNodeDefinition(oView)
'Get the browser node Of the View Using the browser node definition
oViewNode = oTNode.AllReferencedNodes(oNativeBrowserNodeDef).Item(1)
oViewNode.DoPreSelect()
oViewNode.DoSelect()
'MessageBox.Show(oViewNode.BrowserNodeDefinition.Label, "Drawing View Title")
oCount = oCount + 1
Call Get_SelectedNodes(oViewNode , objColl, oOccName, oView)
'//// EXPAND THE SPECIFIC Object ////
Dim oNode As BrowserNode
For Each oNode In objColl
Logger.Info(oNode.FullPath)
oNode.Expanded = True
oNode.DoPreSelect()
oNode.DoSelect()
Next oNode
Next
End Sub
Public Sub Get_SelectedNodes(oViewNode As BrowserNode, ByRef objColl As ObjectCollection, oOccName As String, oView As DrawingView)
Dim oNode As BrowserNode
For Each oNode In oViewNode.BrowserNodes
If oNode.BrowserNodeDefinition.Label = oOccName Then
Call objColl.Add(oNode)
ElseIf oNode.BrowserNodes.Count > 0 Then
Call Get_SelectedNodes(oNode, objColl, oOccName, oView)
ElseIf oNode.BrowserNodes.Count < 0 Then
End If
Next
End Sub
