Here i want to store only L1,L2,L3 etc in a list, except HE,SL and remaining lines of files
How can i do that?
Please help me, i went through QREgExp class defination also, and i wrote code but that seems to be very big and inserts some blank strings into stored list

while(!f.atEnd() && (!line.contains("------------------------------------------")))
 {
 
     if(!line.contains("--     "))
     {
         flag=1;
         QRegExp rx("[\(]([a-z]|[0-9]|[_]|[A-Z])+[\)]");
          rx.indexIn(line);
          QRegExp rx1("([a-z]|[0-9]|[_]|[A-Z])+");
         rx1.indexIn(rx.cap(0));
        captured.append(rx1.cap(0));
          line=f.readLine();
    }
     else if(flag==1)
     {
         flag++;
         captured.pop_back();
         QRegExp rx("[\(]([a-z]|[0-9]|[_]|[A-Z])+[\)]");
              rx.indexIn(line);
               QRegExp rx1("([a-z]|[0-9]|[_]|[A-Z])+");
         rx1.indexIn(rx.cap(0));
        captured.append(rx1.cap(0));
          line=f.readLine();
     }
 
     else if(flag>0)
     {  flag++;
         QRegExp rx("[\(]([a-z]|[0-9]|[_]|[A-Z])+[\)]");
              rx.indexIn(line);
