Qt正则表达式(?(Ff):吃[]?)|(?:[(Ff)eaturing][]?)

In a Qt project I'm having to split a QString by the following separators

在Qt项目中，我必须使用以下分隔符分割QString

Feat.
的壮举。
feat.
的壮举。
Feat
的壮举
feat
的壮举
Featuring
特色
featuring.
特色。
Featuring
特色
featuring
特色

My best try was (?: [Ff]eat[.]? )|(?: [[Ff]eaturing][.]?) as in

我最好的尝试是(?(Ff):吃[]?)|(?:[(Ff)eaturing][]?)

QRegExp xp("(?: [Ff]eat[.]? )|(?: [[Ff]eaturing][.]? )");
QString str = "Eminem Feat. Rihanna";
QStringList list = alist.split(xp);

The above lines of codes doesn't work for me. This is a simple RegExp problem. I'm just too confused. Any sort of help or suggestion would be awesome!

上面的代码行对我不起作用。这是一个简单的RegExp问题。我太糊涂了。任何形式的帮助或建议都是很棒的!

#1

You have an extra character class in the 2nd part of regex.

在regex的第二部分中有一个额外的字符类。

Try using this:

试着用这个:

QRegExp xp("(?: [Ff]eat[.]? )|(?: [Ff]eaturing[.]? )");

And you can combine both of them in one pattern, using ? quantifier, and you don't need the outermost non-capturing group.

你可以把它们结合在一起，使用?量词，你不需要最外面的非捕获组。

QRegExp xp(" [Ff]eat(?:uring)?[.]? ");

#2

Try this pattern:

试试这个模式:

(?: [fF]eat(?:uring)?\.? )

Or replace the spaces with word boundaries

或者用单词边界替换空格

(?:\b[fF]eat(?:uring)?\.?\b)
