Hi NNos2012,

You can get the div tag and can replace the tag in code so that that div will not be visible on front end. I have some code you can try them out...

C#

string replaceString = string.Join(";",
                           File.ReadAllLines("<div id="id1">")
                           ).Replace("@", "<div id="id1" style="display: none;">");

   File.WriteAllText("<div id="id1">", replaceString);
   Console.WriteLine("Done");
   Console.ReadLine();</div></div></div>

Or try the following code:

// Open a file for reading
StreamReader streamReader
streamReader = File.OpenText(fileName)
// Now, read the entire file into a strin
string contents = streamReader.ReadToEnd();
streamReader.Close()

// Write the modification into the same fil
StreamWriter streamWriter=File.CreateText(fileName);

streamWriter.Write(contents.Replace("String1", "String2"));
streamWriter.Close();
