regex replace

[ravas]

Usually regex libraries have a replace or sub function;
however, I could only find:
QRegularExpression::swap
QRegularExpressionMatch::swap

Is swap used for this purpose? I couldn't find any examples, or figure it out.
A basic example would be appreciated.

@ravas I found QString replace.

replace(const QRegularExpression & re, const QString & after)
