灯塔彭于晏

你好，先谢谢你了，代码如下！
能否用正则的形式，搭配上bat，在下面中找出所有 "tag":"XXX" 中  XXX 的内容。
比如下面的内容，最后生成的文本是

オリジナル

采用sed来处理，非正则，仅针对上文。代码简单，可以根据自己需要调整

1. copy /y 35.txt 原文.txt
   
2. sed -i "s/{"tag":/\nmmmmmm/g;s/,"locked/\n/g" 原文.txt
   
3. findstr /i "mmmmmm" 原文.txt>>结果.txt
   
4. sed -i "s/mmmmmm//g;s/"//g" 结果.txt

复制代码

关键语句  s/原内容/新内容/g   。  \把紧跟的字符作为字符识别   \n换行

依靠sed来提取，非正则。仅对上文。语句简单，可自行修改功能。

1. copy /y 35.txt 原文.txt
   
2. sed -i "s/{"tag":/\nmmmmmm/g;s/,"locked/\n/g" 原文.txt
   
3. findstr /i "mmmmmm" 原文.txt>>结果.txt
   
4. sed -i "s/mmmmmm//g;s/"//g" 结果.txt
   
5. pause

复制代码

语句说明  s/原内容/新内容/g  替换。 \对紧跟后面的字符令其识别为字符。\n换行

1. $m=select-string -path file '(?<="tag":")[^"]*' -AllMatches
   
2. foreach( $a in $m.matches )
   
3. {
   
4.     $a.value
   
5. }

1. grep -P -o "(?<="tag":)[^,]*" file
