[文本处理] 注册表REG文件中字符串的替换

xiaofeixiahk

有一个注册表文件，文件名为test.reg，内容如下：

我的问题是如何利用批处理语句来实现替换"[HKEY_LOCAL_MACHINE\sam\sam\domains\account\users\000001F4]"这一行的最后的数字"4"为"5"。 我只知道用for循环能实现，也懂得一些用法，另外，把""V"=hex:00,00,00,00,bc,00,00,00,02,00,01,00,bc,00,00,00,1a,00,00,00,00,00,00,\"这一行及此行下的所有行都删除掉。

希望前辈在给出代码的同时能够指点下具体的实现方法，授人与不如授人渔嘛，感激不尽！
