How i can split a string in more substrings in QT?

Question

I'm new to qt I want to know how I can split a string into substrings with one or more operation. This is an example

QString FileName = "ABCD_1234_5678.exe";

I want this output or substrings: "ABCD" "1234" "5678"`

The QString in my application represents the name of a file that I have read with QDir::entryInfoList

Use `QString x = "ABCD_1234_5678.exe"; QString y = x.left(4); // remove ".exe" QStringList output = y.split("_");` — eyllanesc, Mar 04 '19 at 18:59
Qt has great documentation you know: https://doc.qt.io/qt-5/qstring.html — , Mar 04 '19 at 19:23
https://doc.qt.io/qt-5/qfileinfo.html should help split the extension off the path in `Qt`. — drescherjm, Mar 04 '19 at 20:17
You might consider using regular expressions: `QRegExp` or `QRegularExpression`. — vahancho, Mar 05 '19 at 08:41

You can use this:

QString FileName = "ABCD_1234_5678.exe";
QString FileNameWithoutExtention = FileName.split('.')[0];
QStringList SubStrings = FileNameWithoutExtention.split('_');
qDebug()<<SubStrings;
