Question

Is there a regex expression to find and replace any parentheses with two CAPITAL letters inside of it?

(AB)
(DD)
(OF)
(TO)

Answer 1

Try this to find two caps inside of parens:

\([A-Z]{2}\)

Replacing them depends on the technology you are using. In .NET you would look at the Regex.Replace method:

  string input = "some text";
  string pattern = @"\([A-Z]{2}\)";
  string replacement = "replace value";
  Regex rgx = new Regex(pattern);
  string result = rgx.Replace(input, replacement);
