Multiple xpathexpression with Namespacemanager


Have created an xml document with an xmltextwriter with a namespace, so it
can be validated against an xsd schema.
Later in my application, I want to extract values from the xml and am using

Because I have a namespace in the xml, I have to use the xmlNameSpaceManager
and comile an xpathquery as below:

objXMLXPathNav = objXMLXPathDocument.CreateNavigator()

'//Add namespace manager
'Dim objExpr As XPathExpression =
'Dim objNamespaces As XmlNamespaceManager = New
XmlNamespaceManager(New NameTable)

Dim objXPathNodeIterator As XPathNodeIterator = objXMLXPathNav.Select(objExpr)
While (objXPathNodeIterator.MoveNext())
intValue = CInt(objXPathNodeIterator.Current.Value())
End While

This works fine for finding one node, but I want to match a further 6
different nodes, which are above and below the first node I select

I can't find any examples where multiple xpathexpressions are used.

Do I have to re-create the whole process to create a new xpathexpression
every time, or is there an easier way?
