Regexp replace from bracketed ascii number to the corresponding char

I would like to replace a string



String length = 1+4+1+1+1 = 8

How can I do this with a RegEx replace? (TRegExReplace in Delphi)

Thanks, yes. I would make it using a function, so now I probably need to figure out how to do it for TRegExReplace in Delphi (Pascal).

whith TRegEx do this:

uses System.RegularExpressions;

function TForm1.ReplaceMyStr(const Match: TMatch): String;
  s: String;
  i: Integer;
  Result := '';
  if Match.Success then
    s := Copy(Match.Value, 2, Match.Length-2); //exclude brackets
    if Length(s) > 0 then
      if TryStrToInt(s, i) then
        Result := Chr(i);

procedure TForm1.Button1Click(Sender: TObject);
  regex: TRegEx;
  input: string;
  myEval: TMatchEvaluator;
  iCC := 0;
  input := '<2>Test<3><13><10>';
  myEval := ReplaceMyStr;
  Label2.Caption := regex.Replace(input, '<[^>]+>', myEval);

...but maybe can be easier with stringreplace:
s :=  '<2>Test<3><13><10>';
s := StringReplace(s, '<2>', Chr(2), [rfReplaceall]);
s := StringReplace(s, '<3>', Chr(3), [rfReplaceall]);
s := StringReplace(s, '<10>', Chr(10), [rfReplaceall]);
s := StringReplace(s, '<13>', Chr(13), [rfReplaceall]);
