Two Word QRegExp Help

[mabeeh]

I got it...and it captures the entire string. Here's the code and the output.

QString str = "User Action:";
  QString str1 = "USER ACTION: do this";
  QString str2 = "USER VERIFY: DO SOMETHING ELSE";
  QString str3 = "STEP NUMBER: 1";
 
  QRegExp reg ("^((\\bUSER\\b)(\\s)(\\bACTION:\\b?))(.*$)|((\\bUSER\\b)(\\s)(\\bVERIFY:\\b?))(.*$)|((\\bSTEP\\b)(\\s)(\\bNUMBER:\\b?))(.*$)");
 
  int ireturn = reg.indexIn(str, 0); 
  std::cout << ireturn << std::endl;
  ireturn = reg.indexIn(str1, 0);
  std::cout << ireturn << std::endl;
  QString captured = reg.cap( 0 ); // captured == "letter"
  std::cout << captured.toStdString() << std::endl;
 
  ireturn = reg.indexIn(str2, 0);
  std::cout << ireturn << std::endl;
  captured = reg.cap( 0 ); // captured == "letter"
  std::cout << captured.toStdString() << std::endl;
 
  ireturn = reg.indexIn(str3, 0);
  std::cout << ireturn << std::endl;
  captured = reg.cap( 0 ); // captured == "letter"
  std::cout << captured.toStdString() << std::endl;

QString str = "User Action:";
  QString str1 = "USER ACTION: do this";
  QString str2 = "USER VERIFY: DO SOMETHING ELSE";
  QString str3 = "STEP NUMBER: 1";
  
  QRegExp reg ("^((\\bUSER\\b)(\\s)(\\bACTION:\\b?))(.*$)|((\\bUSER\\b)(\\s)(\\bVERIFY:\\b?))(.*$)|((\\bSTEP\\b)(\\s)(\\bNUMBER:\\b?))(.*$)");
   
  int ireturn = reg.indexIn(str, 0); 
  std::cout << ireturn << std::endl;
  ireturn = reg.indexIn(str1, 0);
  std::cout << ireturn << std::endl;
  QString captured = reg.cap( 0 ); // captured == "letter"
  std::cout << captured.toStdString() << std::endl;

  ireturn = reg.indexIn(str2, 0);
  std::cout << ireturn << std::endl;
  captured = reg.cap( 0 ); // captured == "letter"
  std::cout << captured.toStdString() << std::endl;
  
  ireturn = reg.indexIn(str3, 0);
  std::cout << ireturn << std::endl;
  captured = reg.cap( 0 ); // captured == "letter"
  std::cout << captured.toStdString() << std::endl;
