with following code.

             using (StreamWriter sw = new StreamWriter("result.txt", true))
            {

                while (reader.Read())
                {
                    switch (reader.NodeType)
                    {
                        case XmlNodeType.Element: // The node is an element.
                            sw.Write("<" + reader.Name.ToString());
                            sw.Write(">");
                            break;
                        case XmlNodeType.Text: //Display the text in each element.
                            sw.Write(reader.Value);
                            break;
                        case XmlNodeType.EndElement: //Display the end of the element.
                            sw.Write("                            sw.Write(">");
                            break;
                    }

}

but it throws an exception because the Node name contains whitespace

can anyone help me fix this issue?
