You can use the following code:

QRegExp rx("#([^#]+)#"); // create the regular expression
string text = "qjkfsjkdfn 54df#Sub1#sdkf ++sdf #Sub2#q qfsdf445#Sub3#sdf";
int pos = 0;
while ( (pos = rx.search(text, pos)) != -1 ) // while there is a matching substring
{
     cout << rx.cap(1); // output the text captured in group 1
}
