XmlDocument.Save changes text containing '\t' to tab

I have this issue wherein whenever I save the xml attribute value which contains '\t' (example: MyNetwork\trash), I get "MyNetwork rash". Also, there are some wherein the '\n' in the text get changed to a hexadecimal value.

Below is the code that I am using.

Config mmsConfig = new Config
{
   Path = "MyNetwork\trash"
};

XmlDocument xml = new XmlDocument();
xml.Load(configFile);
XmlNodeList xmlNodeList = xml.SelectNodes("MMS");

foreach (XmlNode node in 
         from XmlNode xmlNode in xmlNodes 
         from XmlNode node in xmlNode.ChildNodes 
         select node)
{
   if (node.Attributes == null)
   {
      throw new ArgumentNullException(configFile, "Unable to locate attributes");
   }

   if (node.Attributes["path"] != null)
   {
      node.Attributes["path"].Value = @config.Path;
   }
}

XmlTextWriter xmlText = new XmlTextWriter(configFile, Encoding.UTF8);
xmlText.Formatting = Formatting.None;

xml.Save(xmlText);
xmlText.Close();

Please help me in this.
