如何在Notepad ++中使用正则表达式保留一部分字符串的同时替换字符串 [英] How to replace a string while while keeping a part of it using regex in Notepad++

问题描述

我有多个记录的文件:例如:

I have file with multiple records: for example:

"datetime": "2018-10-10"
"datetime": "2018-10-11"
"datetime": "2019-01-11"
"datetime": "2018-02-15"

我想替换这个字符串，这样我就可以保留日期值，所以是这样的:

I would like to replace this string such that i can retain the date values, so something of this sort:

"datetime": date("2018-10-10")
"datetime": date("2018-10-11")
"datetime": date("2019-01-11")
"datetime": date("2018-02-15")

我可以使用 "datetime": ".*" 来查找上述记录，但我坚持以上述格式替换它们感谢帮助

I am able to use "datetime": ".*" to find the above records, but am stuck with replacing them in the above format help is appreciated

推荐答案

您可以使用

查找内容:("datetime": )(".*")
替换为:\1date\(\2\)

详情

• ("datetime": ) - 第 1 组(替换模式中的 \1):文字 "datetime": 子字符串
• (".*") - 第 2 组(替换模式中的 \2):"，除换行符，尽可能多，然后是 "(请注意，如果您的内容混合在一起，在这里使用非贪婪模式更安全，".*?")

• ("datetime": ) - Group 1 (\1 in the replacement pattern): a literal "datetime": substring
• (".*") - Group 2 (\2 in the replacement pattern): ", any 0+ chars other than line break chars, as many as possible, and then a " (note that in case your contents are mixed, it is much safer to use a non-greedy pattern here, ".*?")

请注意，替换模式中的 ( 和 ) 必须被转义，因为 Notepad++ 正则表达式替换模式是 Boost 条件替换模式，括号在那里是特殊的".

Note that ( and ) inside the replacement pattern must be escaped as Notepad++ regex replacement patterns are Boost conditional replacement patterns and parentheses are "special" there.
