Here is code I have used in the past that could help.

Dim TOCollection
Dim Msg
Dim RepositoryFrom
Dim TestObject
Dim ln, cn
Dim PropertiesCollection
Dim Property

Set RepositoryFrom = CreateObject(''Mercury.ObjectRepositoryUtil'')
RepositoryFrom.Load ''z:SORMySOR.tsr'' 
' Write your OR path here 


Set TOCollection = RepositoryFrom.GetAllObjectsByClass(''WebEdit'') 

For i = 0 To TOCollection.Count - 1
'print i &''#####################''   & i
	Set TestObject = TOCollection.Item(i)
	ln = RepositoryFrom.GetLogicalName(TestObject)
	
	cn = TestObject.GetTOProperty(''name'')
	
'print ''ln ='' & ln & ''     '' & cn
	
	If cn = ''WebEdit'' Then
		Set PropertiesCollection = TestObject.GetTOProperties()
	
		For n=0 To PropertiesCollection.Count - 1
			Set Property = PropertiesCollection.Item(n)
			Msg = Msg & Property.Name & ''-'' & Property.Value & vbNewLine
			If Property.Name = ''html id'' Then
				idArray = Split(Property.Value, ''d'')
				Msg2 = idArray(0) & '' - '' & idArray(1) & vbNewLine
				newId = idArray(0) & ''d_WIN_0_ '' & idArray(1) 
				'TestObject.SetTOProperty Property.Value, newId
				TestObject.SetTOProperty ''html id'',newId
				RepositoryFrom.UpdateObject TestObject
				RepositoryFrom.Save
				Msg3 = Msg & ''New ID - '' & Property.Name & ''-'' & Property.Value & vbNewLine
			End If
		Next
'print cn & vbnewline & ln &vbnewline & Msg3 & VBnewline & ''Desired ID - '' & newId & VBnewline & VBnewline
	End If
	RepositoryFrom.Save
Next
