var nodeNames = new [] { "Name", "Description", "Synonym_Name" };

var nodeContents = nodeNames
                       .Select(xmlDoc.GetElementsByTagName)
                       .Select(_ => _.Cast<XmlNode>())
                       .SelectMany(_ => _)
                       .Select(node => 
                       {
                            var stringBuilder = new StringBuilder();

                            var settings = new XmlWriterSettings { OmitXmlDeclaration = true, Indent = true };

                            using (var writer = XmlTextWriter.Create(stringBuilder, settings))
                            {
                                node.WriteTo(writer);

                                writer.Flush();

                                return stringBuilder.ToString();
                            }
                        });

var box = new System.Windows.Controls.TextBox();

box.Text = string.Concat(nodeContents);
