1、非捕获分组( non-capturing group) 使用语法:(?:regex)这里的?和:都是语法的组成部分;这种分组正则表达式引擎不会捕获它所匹配的内容即不会为非捕获型分组分配组号; 样例说明:Set(?:Value)?表达式匹配SetValue或者Set,但是不能通过group(1)的方式获取Value文本串,Set(Value)?则可以获取的

所以你可以使用(logger\.[tdiwe]\(")[^"]*和替换字符串\1filename:123。你的代码看起来像这样：
然后它将停止并将结果testname保存在捕获组内 result.group(1)这是访问第一个捕获组中的值的方法。

For example, consider the pattern: /(ab)+c/. The parentheses create a group, and the “+” quantifier applies to the group as a whole. This pattern would match “abc”, “ababc”, “abababc”, etc. Grouping also enables capturing. Using parentheses, you can capture and refer to the ...
