Two Word QRegExp Help

[mabeeh]

I'm having a problem setting up a two word QRegExp. In Example #1 I'm able to pick out USER from str1. However, in Example #2 I'm not able to pick out USER ACTION:
What am I doing wrong? Thanks!

EXAMPLE #1:

QString str = "User Action:";
QString str1 = "USER ACTION:";
 
  QRegExp reg ("^\\bUSER\\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;

QString str = "User Action:";
QString str1 = "USER ACTION:";
  
  QRegExp reg ("^\\bUSER\\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;

EXAMPLE #2:

QString str = "User Action:";
QString str1 = "USER ACTION:";
 
 QRegExp reg ("^\\bUSER\\b\\s\\bACTION:\\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;

QString str = "User Action:";
QString str1 = "USER ACTION:";
  
 QRegExp reg ("^\\bUSER\\b\\s\\bACTION:\\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;
