[SOLVED] Can't understand how to work with QRegExp

Leon

I have in a qstring this:
@R836044429,20120912,20120921,28
R497476295,20120916,20120921,16@

i want to separate each one that has coma and for example qdebug them in a new line..like
@R836044429
20120912
20120921
28
R497476295
20120916
20120921
16@

i have read a lot of times the documentation but i just lose it in a point.. what have i done until now..

@QTextStream in(&qstringnamehere);
while(!in.atEnd())
{
QString line=in.readLine();

        QRegExp regex("R.*,");
        regex.setMinimal(true);

        QString match;
        int pos = 0;

        while ((pos = regex.indexIn(line, pos)) != -1)
        {
            match=regex.cap(0).remove(QChar(' '),Qt::CaseInsensitive);
            pos += regex.matchedLength();
        }
        if(match.isEmpty()){
            return;
        }
        QString current=match;
        current.replace(",","");
        qDebug(QString(current+"\n").toLocal8Bit());

        QRegExp regex2(",.*,");
        regex2.setMinimal(true);

        QString match2;
        pos = 0;

        while ((pos = regex2.indexIn(line, pos)) != -1)
        {
            match2=regex2.cap(0).remove(QChar(' '),Qt::CaseInsensitive);
            pos += regex2.matchedLength();
        }
        if(match2.isEmpty()){
            return;
        }
        QString current2=match2;
        current2.replace(",","");
        qDebug(QString(current2+"\n").toLocal8Bit());
    }@

what am i doing wrong?
p.s i don't know how to say from it to search from the 3rd coma until the end of the line
i don't know when the captured texts are more than one how to separate them :/

You don't need a QRegExp for that. Just use QString::split and split on the comma.

Leon

yes but this will make
@28
R497476295@

as one because they are not separated by a coma..

andre

Ok, so you split on both a line break or a comma. The documentation of QString::split has a nice example of using a very simple RegExp expression for something like this, that should work for you as well.

Leon

This seems to work for me..

@ QStringList list = current_clipboard.split(QRegExp("\W+"), QString::SkipEmptyParts);
@

because \W stands for a non-word character :)
Thanks Andre!

andre

Yes, that is the one I was eyeing :-)
