Thanks, 

I'm having a problem trying to navugate with it:

I'm reading an XMLDocument in from a file:

        Dim document As XmlDocument = New XmlDocument()
        document.Load("ChimneyFire.xml")
        Dim navigator As XPathNavigator = document.CreateNavigator()

        Dim manager As XmlNamespaceManager = New 
XmlNamespaceManager(navigator.NameTable)
        manager.AddNamespace("IncidentDetails", 
"http://www.fire.gov.uk/schemas/Incident")

I then need to change the value of an element several levels down

I think the XPath expression is something like:
"/IncidentDetails:Incident/IncidentDetails:Identifier" _
        & "/IncidentDetails:FRSIncidentNumber"

I can't see how to get the position of the navigator to move to the right 
place.
