why this error message

For Each onode As XmlNode In oDocument
If onode.ChildNodes.Count > 0 Then
For Each onode2 As XmlNode In onode.ChildNodes
If onode2.ChildNodes.Count > 0 Then
txtResult2.Text = onode2.SelectSingleNode//here("EntityID").InnerText

Else

End If
Next
End If
Next
End If
Session("Request") = Nothing
End Sub 'Put user code to initialize the page here

txtResult2 has not yet been initialized at that point.

Dim oDocument As New XmlDocument
oDocument.LoadXml(txtResult1.Text)


For Each onode As XmlNode In oDocument

At which point in the code did you initialize the txtResult2 variable.

The other possibility is that
onode2.SelectSingleNode("EntityID") returns null.
eg, there is no EntityID ancestor from onode2.

But yeah, that can't possibly be all your code.
