Notepad++ RegEx帮助-从这里替换到另一个

Question

好吧，是这样的：

 I'm writing a huge programming file, and, while near the end, I realize that I made a stupid mistake. Basically, the text looks like this now:  

"usable_by"  
{  
    //Here is a line(s) that looks like the following:  
    "one" "1"  
    "two" "1"  
    //It can have any combination of these lines, with "one" or "two" in the lines above going up to nine.  
}  

评论显然不是程序的一部分，是你的笔记，以帮助我。

我希望将这些实例替换为所有九个属性，因此如下所示：

{
    "one" "1"
    ...
    "nine" "1"
}

和..。是2-8岁。

我猜您将不得不设计一种方法来替换{和}之间的任何东西(但只在"usable_by“标记上，以便其他标记不会被破坏)。

任何帮助都是非常感谢的。此外，我希望你能解释它，而不是仅仅给我这条正则线可能是什么。

谢谢!

Answer 1

拜托，拜托，在运行之前备份一下你的资料。它对我有效，但我只有一点点的样本文本。

找出什么：

("usable_by"\s*\{\s*\n)(\s*)[^}]*\n(\s*)

代之以：

\1\2"one" "1"\n\2"two" "1"\n\2"three" "1"\n\2"four" "1"\n\2"five" "1"\n\2"six" "1"\n\2"seven" "1"\n\2"eight" "1"\n\2"nine" "1"\n\3

Regex细分：

(              # Start of first capturing group. Save for use in the replacement.
  "usable_by"  # This should be obvious.
  \s*          # \s match any whitespace character, the * means "zero or more."
  \{           # The opening curly brace.
  \s*          # More optional additional space.
  \n           # Newline.
)              # End of first capturing group.

(\s*)          # Second capturing group. Grabs the attribute indentation.

[^}]*          # Everything up to the closing curly brace.
               # Except it'll backtrack a bit so we can get rid of the next two.
\n             # Newline, the last before your final } line.

(\s*)          # Third capturing group. Picks up the indentation
               # leading up to the closing curly brace.

更换细目：

\1             # Back-reference to the first capturing group. Puts it here.
\2             # And the second, your indentation. We'll reuse this a bunch.
"one" "1"      # Your first attribute.
\n             # A newline

\2             # There's your indentation again.
"two" "1"      # And second attribute.
\n             # And newline.

...            # etc. don't really need to explain them all individually.

\2"nine" "1"\n # Indentation, ninth attribute, newline.
               # You're used to all this by now.

\3             # The third capturing group. The indentation leading
               # up to your closing }.
