A problem with RegExp

[8Observer8]

Hi,

I have the string: "Valencia 7x17"

I want to see:

0
"Valencia 7x17"
"Valencia"
"7"
"17"

But I see:

0
"Valencia 7x17"
"Valencia"
"17"
""

main.cpp

#include <QCoreApplication>
#include <QRegExp>
#include <QtDebug>
 
int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);
 
    // ([\w]+) ([\d])x([\d]+)\/([\d]x[\d]+) ([A-Z]([\d.]+)) .+ ([\w]+)
    // Valencia 7x17/5x112 D70.1 ET48 Silver
 
    QRegExp reCap("^([\\w]+)\\s([\\d])x([\\d]+)$");
    qDebug() << reCap.indexIn("Valencia 7x17");
    qDebug() << reCap.cap(0);
    qDebug() << reCap.cap(1);
    qDebug() << reCap.cap(3);
    qDebug() << reCap.cap(4);
 
    return a.exec();
}

#include <QCoreApplication>
#include <QRegExp>
#include <QtDebug>

int main(int argc, char *argv[])
{
    QCoreApplication a(argc, argv);

    // ([\w]+) ([\d])x([\d]+)\/([\d]x[\d]+) ([A-Z]([\d.]+)) .+ ([\w]+)
    // Valencia 7x17/5x112 D70.1 ET48 Silver

    QRegExp reCap("^([\\w]+)\\s([\\d])x([\\d]+)$");
    qDebug() << reCap.indexIn("Valencia 7x17");
    qDebug() << reCap.cap(0);
    qDebug() << reCap.cap(1);
    qDebug() << reCap.cap(3);
    qDebug() << reCap.cap(4);

    return a.exec();
}
