Trouble trying to edit vbProj using XMLDocument

[ZAK]

I have written a small program to edit VBProject files to all file get
written to same location and other things.

I need help . I can't find a way of selecting the OutputPath, I just get
either can't find node or "Expression must evaluate to a node-set."

Code

xDoc.Load(vbProjFile)

Dim Query As String =
"VisualStudioProject/VisualBasic/Build/Settings/Config/*[@Name='Release']"

Dim node As XmlNode = xDoc.SelectSingleNode(Query)
If node Is Nothing Then
Throw New Exception("Error Can't find node " + Query)
End If

console.writeline (xDoc.Attributes.GetNamedItem("OutPutPath").Value)
