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 '

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:
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
