basic question xmldocument and asp.net

[edelwater]

why do i get "System.NullReferenceException: Object reference not set to an instance of an object"

on this :

Dim doc As System.Xml.XmlDocument = New System.Xml.XmlDocument()

If System.IO.File.Exists(Server.MapPath("/test.xml&quot) Then
doc.Load(Server.MapPath("/test.xml&quot)
Dim root As System.Xml.XmlNode = doc.DocumentElement
Else
Dim root As System.Xml.XmlNode = doc.DocumentElement

Dim comments As System.Xml.XmlElement = doc.CreateElement ("testa&quot
root.AppendChild(comments)
End If

?? ( on the line root.Appendcild(comments) ?)

sorry already found out, should be :

Dim root As System.Xml.XmlNode = doc.CreateElement("Comments&quot
doc.AppendChild(root)

Dim filename As System.Xml.XmlElement = doc.CreateElement("Filename&quot
