UAU!
Didn't worked but you gave me the answer because this worked:

{$mode objfpc}{$H+}
uses
  RegExpr;
var
  InputStr: string;
  r: TRegExpr;
begin
  r:= TRegExpr.Create;
  try
    InputStr := '<a href="/3604669/trabalho-28-07-2014-pg-1"
title="Página 1, pg 1, 28/07/2014"> 28/07/2014 </a>';
    r.Expression := '(\/)([0-9]+)(\/.*?pg\-)(\d+)(.*?)"';
    r.Exec(InputStr);
    ShowMessage(r.Substitute('$1#p1$3#p2$5'));
 finally
    r.Free;
  end;
end;

I finished this task yesterday making a new method for my own TRegExpr
but your tip is more elegant, thank you!
