This question is an expanded question of this : How to replace QRegExp in a string?
In that question, problem is solved. But now I need to use QRegularExpression instead of QRegExp. How should I transfer the answer of Toby Speight?

1What have you tried? In particular, what makes you think that simply replacing `QRegExp` with `QRegularExpression` won't work in this case (with the proviso you change `Qt::CaseInsensitive` to `QRegularExpression::CaseInsensitiveOption`)? – G.M. Sep 14 '18 at 10:14

@G.M.: thanks for your answer, Actually that is what i am looking for. I dont know how to replace `Qt::CaseInsensitive` in `QRegularExpression`. :) – songvan Sep 14 '18 at 12:37

But G.M. said exactly what to replace it with: `QRegularExpression::CaseInsensitiveOption`, it's of type `QRegularExpression::PatternOption`. – Kuba hasn't forgotten Monica Sep 14 '18 at 16:46

QRegExp case insensitive search mode is enabled with Qt::CaseInsensitive.
When you use QRegularExpression that is based on PCRE regex engine, you may use QRegularExpression::CaseInsensitiveOption:
The pattern should match against the subject string in a case insensitive way. This option corresponds to the
/imodifier in Perl regular expressions.

In python, it's:
re = QRegularExpression(pattern, QRegularExpression.CaseInsensitiveOption | QRegularExpression.DotMatchesEverythingOption)
And if you need 2 options
re = QRegularExpression(pattern, QRegularExpression.CaseInsensitiveOption | QRegularExpression.DotMatchesEverythingOption)
