C# 中的正则表达式：在特殊字符 + 特定文本 + 直到特殊字符之后匹配

Question

I am looking for a pattern that matches everything after the special character } then match a text and then till first special character.

this will be clear with example.my string is like

string a = @"}var e=l.visible}.abc.jYOxx{margin-top:0px}.acOxx{margin-top:0px}";

I want to extract everything after last } and text matching is ".jYOxx" and then everything before first } .

result of my desired regex will be:

.abc.jYOxx{margin-top:0px}

I wrote this:

MatchCollection matchesSource = Regex.Matches(a, @"\}(.*?).jYOxx(.*?)}", RegexOptions.Multiline);

my result is:

}var e=l.visible}.abc.jYOxx{margin-top:0px}

Logically I have a string of css classes and I have class name to match I want to extract that css class only. Please help I have wasted whole day in it.

Answer 1

You can match any char except the curly brackets before matching .jYOxx

If you also do not want to match whitspace chars, you can add \s to the negated character class [^{}\s]

[^{}]*\.jYOxx{[^{}]*}
