Trouble parsing using simple QRegExp

[johnny_sparx]

I wish to extract some parts of a formatted string, so I opted to use QRegExp. I tested the expression so I know it works alright, but can't seem to get it to work using Qt .

A snippet of test code is below - it is supposed to dump the sub-expressions into a text file.

Any help is appreciated.

JS

QFile Temp;
  QTextStream Output(&Temp);
 
  Temp.setFileName("temp.txt");
  Temp.open(QIODevice::WriteOnly | QIODevice::Text);
 
    // I want to extract "PATIENT0001/", "STUDY0001/", and "SERIES0001 "
    QRegExp rx("[a-zA-Z0-9]*[\/\\ ]{1,2}");
    QString str = "PATIENT0001/STUDY0001/SERIES0001 DIRECTORY_1";
 
   int pos = 0;
    while ((pos = rx.indexIn(str, pos)) != -1)
        {
        Output << rx.cap(1)<<"\n";
        pos += rx.matchedLength();
        }

QFile Temp;
  QTextStream Output(&Temp);

  Temp.setFileName("temp.txt");
  Temp.open(QIODevice::WriteOnly | QIODevice::Text);

    // I want to extract "PATIENT0001/", "STUDY0001/", and "SERIES0001 "
    QRegExp rx("[a-zA-Z0-9]*[\/\\ ]{1,2}");
    QString str = "PATIENT0001/STUDY0001/SERIES0001 DIRECTORY_1";

   int pos = 0;
    while ((pos = rx.indexIn(str, pos)) != -1)
        {
        Output << rx.cap(1)<<"\n";
        pos += rx.matchedLength();
        }
