Hello,

May I define an empty node in a XML file then do something?
The following is vb.net code.
Code: 
Dim ReasonNodeList As Xml.XmlNodeList = SomeNode.SelectNodes("./REASON_CODE/REASON")
I mean there is no such a node ./REASON_CODE

Empty node is not the same as non-existing node (your "no such node"). The XmlNodeList instance just gives you .Count=0. You can, in this sense, do "something" with it. It is not a runtime error.
