Соответствие регулярному выражению не может найти текст между двумя символами

Question

Я пытаюсь получить весь текст от Features<br> до Specification<br> из всего узла html. Я уже пробовал совпадать с Regex, как показано ниже, но он ничего мне не возвращает. Почему это не удается - любая идея?

C#

string wholeString = "html text goes here";
string onlyFeatures = Regex.Match(wholeString, @"Features<br>(.*)Specification<br>").Groups[1].Value;

onlyFeatures переменная ничего не возвращает

Answer 1

Это потому, что

(.*)

не соответствует разрыву строки. Используйте

Regex.Match(wholeString, @"Features<br>([.\s\S]*)Specification<br>").Groups[1].Value;

вместо

Answer 2

Размер. соответствует всем символам, кроме разрывов строк \ n

Вы можете указать RegexOptions.SingleLine, чтобы изменить это:

onlyFeatures = Regex.Match(wholeString, @"Features<br>(.*)Specification<br>", RegexOptions.SingleLine).Groups[1].Value;
