Hi

I simply want to return the count of a condition in an XML file using XPath.

My XPath expression works fine and have tested in XML Spy and it returns the right count but when I evaluate the expression, it always returns 0.

Dim xpd As New XPathDocument(strFileName)
Response.Write(fi.Name & "<br/>")
Dim xpn As XPathNavigator = xpd.CreateNavigator
Dim intCount As Int32 = xpn.Evaluate("count(Expression)")
Response.Write(fi.Name & "<br/>")

Only ever had to return a node set before. Am I going about returning a single value in the right way?

Any thoughts?
