替换双引号内所有出现的制表符

Question

最后，我想替换 " 中包含的所有 \t 我目前正在Regex101 尝试我的正则表达式的各种迭代......这是我迄今为止最接近的......

originString = blah\t\"blah\tblah\"\t\"blah\"\tblah\tblah\t\"blah\tblah\t\tblah\t\"\t\"\tbleh\"
regex = \t?+\"{1}[^"]?+([\t])?+[^"]?+\"
\t?+       maybe one or more tab
\"{1}      a double quote
[^"]?+     anything but a double quote
([\t])?+   capture all the tabs
[^"]?+     anything but a double quote
\"{1}      a double quote

我的逻辑有缺陷！ 我需要您的帮助来对制表符进行分组。

Answer 1

仅使用 "[^"]+" 正则表达式匹配双引号子字符串（如果没有要考虑的转义序列）并仅在匹配评估器内替换匹配项中的制表符：

var str = "A tab\there \"inside\ta\tdouble-quoted\tsubstring\" some\there";
var pattern = "\"[^\"]+\""; // A pattern to match a double quoted substring with no escape sequences
var result = Regex.Replace(str, pattern, m => 
        m.Value.Replace("\t", "-")); // Replace the tabs inside double quotes with -
Console.WriteLine(result);
// => A tab here "inside-a-double-quoted-substring" some    here

你可以用这个：

\"[^\"]*\"
