如何使用正则表达式提取子字符串 [英] How to extract a substring using regex

问题描述

我有一个字符串，里面有两个单引号，'字符。在单引号之间是我想要的数据。

I have a string that has two single quotes in it, the ' character. In between the single quotes is the data I want.

如何编写正则表达式以从以下文本中提取我想要的数据？

How can I write a regex to extract "the data i want" from the following text?

mydata = "some string with 'the data i want' inside";

推荐答案

假设您想要单引号之间的部分，请使用此使用 Matcher进行正则表达式 ：

Assuming you want the part between single quotes, use this regular expression with a Matcher:

"'(.*?)'"

示例：

String mydata = "some string with 'the data i want' inside";
Pattern pattern = Pattern.compile("'(.*?)'");
Matcher matcher = pattern.matcher(mydata);
if (matcher.find())
{
    System.out.println(matcher.group(1));
}

结果：

the data i want
