Problem with setting the value on a node of type element in xml

Hi there,

I am trying to add a new record to my XML file. I was able to create the record and its fields, but when I tried to add values to the fields, I got the error: "Cannot set a value on node type: Element".

I am confident that I have something missing in my code, that it is not making it recognize the ability to set the value of my elements.

Here is a sample of my code:

        XmlDocument SrcDoc = new XmlDocument();
        SrcDoc.Load(xmlfile);
        XmlNode RootNode = SrcDoc.DocumentElement;

        //create a new table node
        XmlNode Newtable = SrcDoc.CreateNode(XmlNodeType.Element, "table", "");
        //create the sub node
        XmlNode ExtNode = SrcDoc.CreateNode(XmlNodeType.Element, "Ext","");
        //fill the data in ----------------------------------my error is here
        ExtNode.Value = newext;   // being passed to the subroutine

        //add the node to the new table node
        Newtable.AppendChild(ExtNode);
        //add the new table node to the root
        RootNode.AppendChild(Newtable);
        //save the docment back to the file
        SrcDoc.Save(xmlfile);


Thank you in advance for your prompt help.

replace this  

   //create a new table node
        XmlNode Newtable = SrcDoc.CreateNode(XmlNodeType.Element, "table", "");
        //create the sub node
        XmlNode ExtNode = SrcDoc.CreateNode(XmlNodeType.Element, "Ext","");
        //fill the data in ----------------------------------my error is here
        ExtNode.Value = newext;   // being passed to the subroutine

to


     //create a new table node
        XmlNode Newtable = SrcDoc.CreateElement("table");
        //create the sub node
        XmlNode ExtNode = SrcDoc.CreateElement("ext");
        //fill the data in ----------------------------------my error is here
        ExtNode.InnerText= newext;   // being passed to the subroutine

Thank you! It works perfectly.

Is it possible to highlight the reason why the second case with CreateElement worked, while the CreateNode did not work?

Thank you again for your prompt response.
