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.

Escape the \, otherwise \t will be interpreted as a special character,

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

Check out the Instantiating a String object section in String Class on MSDN:

Note that in C#, because the backslash (\) is an escape character, literal backslashes in a string must be escaped or the entire string must be @-quoted.

\t and \n are escape sequences so you need to escape their \ to \\t or \\n

\t converts to tab(6 spaces)

\n converts to new line

You can use a @ symbol before to escape these.

string p = @"MyNetwork\trash";

The problem is that \t in a string creates a tab character (similar to how \n creates a new line, \" creates a speech mark and \\ creates a backwardslash). Remember, whenever you put a \ in a string, it needs to be doubled up. Replace the \t with \\t and it should work.

Alternatively, put an @ before the string e.g. @"MyNetwork\Trash". Note that if an @ appears before the string and you want to put a " in the string, you need to use "" e.g. @"A speechmark looks like this: ""."
