Javascript 正则表达式匹配由一对字符括起来的项目？

Question

我想要一个正则表达式来匹配字符 (* 和 *) 之间的所有内容。我还需要在结果中匹配 (* 和 *)。

例如；

这样的正则表达式应用于下面的代码；

(*
  * Something here
  * Many things can appear here
  * More things can appear here
  * Added another can appear here
*)

(*****************************************) Something here

Something here (*****************************************) 


(* Content can also exist here *) Something here

Something here (* Content can also exist here *) 


(Some content here ) (* Content can also exist here *) 

  * Something here
  * Many things can appear here
  * More things can appear here
  * Added another can appear here

结果只包含；

(*
  * Something here
  * Many things can appear here
  * More things can appear here
  * Added another can appear here
*)

(*****************************************) 

(*****************************************) 


(* Content can also exist here *) 

(* Content can also exist here *) 

(* Content can also exist here *)

([\(\*].*(?:\*\)))

但它似乎没有按预期工作。

假设没有嵌套或转义括号，您可以在 Javascript 中使用此正则表达式:

/\(\*[\s\S]*?\*\)/g

• \*\):匹配结束*)
