     // Write the root element.
     writer.WriteStartElement("root");

     writer.WriteStartElement(XmlConvert.VerifyName(tag));
     }
     catch (XmlException e){
        Console.WriteLine(e.Message);
        Console.WriteLine("Convert to a valid name...");
        writer.WriteStartElement(XmlConvert.EncodeName(tag));

     writer.WriteEndElement();

     writer.Close();
  }
}

Imports System.Xml

Public Class Sample

    Public Shared Sub Main()
        Dim writer As New XmlTextWriter("out.xml", Nothing)
        Dim tag As String = "item name"

        End Try

        writer.WriteString("hammer")
        writer.WriteEndElement()
