VB.NET add an element to the XML document with LINQ to XML
- by Bayonian
Hi,
I'm adding an element to existing XML doc with the following code:
Dim theXMLSource As String = Server.MapPath("~/Demo/") & "LabDemo.xml"
Dim nodeElement As XElement
Dim attrAndValue As XElement = _
<LabService>
<ServiceType>
<%= txtServiceType.Text.Trim %>
</ServiceType>
<Level>
<%= txtLevel.Text.Trim %>
</Level>
</LabService>
nodeElement.Add(New XElement(attrAndValue))
nodeElement.Save(theXMLSource)
It makes error like this:
System.NullReferenceException: Object reference not set to an instance of an object.
Object reference not set to an instance of an object.
Error line: nodeElement.Add(New XElement(attrAndValue))
I debugged it but I couldn't get the error yet. Can you show what the problem is? Thank you
