Matching a regular expression in string.

[NIXIN]

I am trying something like below,

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

QString str = "((Hello1 and Hello2) in Hello.World)";

QString matchWord = "Hello;

qDebug() << str.contains(QRegExp("\\b" + matchWord + "\\b"));

return a.exec();
}

I am getting output as true. I want to what's wrong??

My intention is to match only a complete word, like "Hello".

Can anyone help me with this?

I think the engine matches the "Hello.World", treating the dot (.) as a word boundary.

You can check where the match happened using QRegExp API to be sure.

BTW. It is recommended to use QRegularExpression in Qt5 - QRegExp is just a leftover from Qt4 times.

can you provide a small piece of code

Sure, they are in the docs: http://doc.qt.io/qt-5/qregexp.html#code-examples

indexIn() method should interest you in this case.
