替换两个引号

Question

我无法找到解决这个简单问题的方法。

我想替换两个连续''或``by“。

Input:
    some ``text'' dspsdj
Out: 
    some "text"

为什么：

   s.replaceAll("[`{2}'{2}]", "\"")
Out:  
   some ""text""  

???

谢谢

Answer 1

你应该这样做：

s.replaceAll("``|''", "\"")

您可能打算这样做：

s.replaceAll("[`']{2}", "\"")

但这不完全正确

Answer 2

String input = "some ``text'' dspsdj";
String output = input.replaceAll("`{2}|'{2}", "\"");

Answer 3

将基数放在课后：

.replaceAll("[`']{2}", "\""));

Answer 4

试试这个：

String resultString = subjectString.replaceAll("([\"'`])\\1", "\"");

<强>解释

<!--
(["'`])\1

Match the regular expression below and capture its match into backreference number 1 «(["'`])»
   Match a single character present in the list “"'`” «["'`]»
Match the same text as most recently matched by capturing group number 1 «\1»
