QRegExp

"TOTAL : <COUNT> LINE."

I want split only <COUNT> with QRegExp, how can do this ?

[bvs]

Try the following code:

QString line1("TOTAL: 534 LINE.");
QRegExp rx("TOTAL: (\\d+) LINE.");
if (rx.indexIn(line1) != -1) {
	qDebug() << "count in line1 = " << rx.cap(1);
}

QString line1("TOTAL: 534 LINE.");
QRegExp rx("TOTAL: (\\d+) LINE.");
if (rx.indexIn(line1) != -1) {
	qDebug() << "count in line1 = " << rx.cap(1);
}

To copy to clipboard, switch view to plain text mode 

The important thing are the parentheses around "(\\d+)", which capture the matching text. You can access this text with cap() as shown.
