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:

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
