本文介绍了用双引号替换所有出现的Tab字符的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
最后,我要替换所有包含在
$ b中的 \t
$ b我目前在 Regex101 上尝试使用正则表达式的各种迭代...这是我最近的一次远...
In the end, I will want to replace all the \t
that are enclosed within "
I'm currently on Regex101 trying various iterations of my regex... This is the the closest I have so far...
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!
我需要您对制表符进行分组。
My logic is flawed! I need your help in grouping the tab characters.
推荐答案
匹配双引号的子字符串仅使用 [^] +
正则表达式(如果没有要解释的转义序列)并替换选项卡insi仅在比赛评估程序内进行比赛:
Match the double quoted substrings with a mere "[^"]+"
regex (if there are no escape sequences to account for) and replace the tabs inside the matches only inside a match evaluator:
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
