Question

Unfortunately, despite having tried to learn regex at least one time a year for as many years as I can remember, I always forget as I use them so infrequently.(不幸的是，尽管尽我所能记住，试图每年至少学习一次正则表达式长达多年，但我却经常忘记，因为我很少使用它们。)

This year my new year's resolution is to not try and learn regex again - So this year to save me from tears I'll give it to Stack Overflow .(今年，我新年的决心是不要再尝试学习正则表达式- 因此，今年，为了让我免于眼泪，我将把它交给Stack Overflow 。) (Last Christmas remix).(（去年圣诞节混音）。) I want to pass in a string in this format {getThis} , and be returned the string getThis .(我想以{getThis}格式输入字符串，并返回字符串getThis 。) Could anyone be of assistance in helping to stick to my new year's resolution?(有人能协助我们坚持我的新年决议吗？) Related questions on Stack Overflow:(有关堆栈溢出的相关问题：) How can one turn regular quotes (ie ', ") into LaTeX/TeX quotes (ie `', ``'')(如何将常规引号（即“，”）转换为LaTeX / TeX引号（即“''，“''）) Regex: To pull out a sub-string between two tags in a string(正则表达式：在字符串中的两个标签之间提取子字符串) Regex to replace all \n in a String, but no those inside [code] [/code] tag(正则表达式替换字符串中的所有\ n，但不替换[code] [/ code]标记内的所有\ n)   ask by ChrisInCambo translate from so

Answer 1

Try(尝试)

/{(.*?)}/ That means, match any character between { and }, but don't be greedy - match the shortest string which ends with } (the ? stops * being greedy).(这意味着，匹配{和}之间的任何字符，但不要贪婪-匹配以}结尾的最短字符串（？停止*为贪婪）。) The parentheses let you extract the matched portion.(括号使您可以提取匹配的部分。) Another way would be(另一种方式是) /{([^}]*)}/ This matches any character except a } char (another way of not being greedy)(这匹配除} char以外的任何字符（不贪婪的另一种方式）)
