使用正则表达式在双花括号内获取值 [英] Get values inside double curly braces with regex

问题描述

通过此字符串:

dfasd {{test}} asdhfj {{te{st2}} asdfasd {{te}st3}}

我想获得以下子字符串:

I would like to get the following substrings:

test, te{st2, te}st3

换句话说，我想将所有内容都保留在双花括号中，包括单花括号.

In other words I want keep everything inside double curly braces including single curly braces.

我不能使用这种模式:

{{(.*)}}

因为它与第一个{{和最后一个}}之间的整个内容匹配:

because it matches the whole thing between first {{ and last }}:

test}} asdhfj {{te{st2}} asdfasd {{te}st3

我设法用此正则表达式模式获得了前两个:

I managed to get the first two with this regex pattern:

{{([^}]*)}}

有什么办法可以使用正则表达式来获取全部三个?

Is there any way to get all three using regex?

推荐答案

尝试 {{(.*?)}} .

.*?意味着在}}匹配后立即进行懒惰/非贪婪搜索=>，它将捕获找到的文本并停止查找.否则，它将进行贪婪的搜索，因此从第一个{{开始，最后一个}}开始.

.*? means to do a lazy / non greedy search => as soon as }} matches, it will capture the found text and stop looking. Otherwise it will do a greedy search and therefore start with the first {{ and end with the very last }}.
