It's a bit hard to know exactly what you want given the example above,
since the .* would match the entire input string.
But like Tony said, you can make references to the capturing groups in
the replacement string, so e.g.
#include <QString>
#include <QRegularExpression>
#include <QtDebug>
int main(void) {
QString s = "Hello Jane and Joe";
qDebug() << s.replace(QRegularExpression("(Jane|Joe)"), "little \\1");
return 0;
}
will print
"Hello little Jane and little Joe"
I don't think you can reference capturing groups by name, but that's
just a minor inconvenience.
