  xmlSettings.Indent = true;
  xmlSettings.Encoding = Encoding.UTF8;
  using (XmlWriter writer = XmlWriter.Create(
    filePath,
    xmlSettings
    ))
  {
    writer.WriteStartDocument();
    writer.WriteStartElement("root");
    {
      writer.WriteStartElement("property");

      {
        foreach (string value in values)
        {
          writer.WriteStartElement("value");
          writer.WriteAttributeString("name", value);                                    
          writer.WriteString(value);

  XPathDocument doc = new XPathDocument(filePath);
  XPathNavigator nav = doc.CreateNavigator();
  XPathNodeIterator nodeIterator = nav.Select("/root");
  foreach (XPathNavigator node in nodeIterator)
  {
    Console.WriteLine("Property Attribute: {0}",node.SelectSingleNode("property").Value);
    Console.WriteLine("Property Value: {0}",node.SelectSingleNode("property").GetAttribute("name",""));
    foreach (XPathNavigator subNode in node.Select("values/value"))
    {
      Console.WriteLine("Value Attribute: {0}", subNode.Value);
      Console.WriteLine("Value Value: {0}", subNode.GetAttribute("name", ""));
    }
