我正在寻找一种方法来替换表单的所有实例：
model->variable
其中
models[variable][index]
变量几乎可以是字母和数字的任意组合，可能定义为 [0-9a-Z]{4,12}。
文本中有数百个这样的变量。我需要知道找到的字符串“变量”的确切形式才能在替换中使用它。有没有办法“记住”该字符串并在以后使用它？或者任何其他方法/软件在这种情况下可以提供帮助？
提前致谢。
如果你能顺便将“变量”转换为大写，那就太棒了。
I'm looking for a way to replace all instances of a form:
model->variable
with
models[variable][index]
where variable can be pretty much any combination of letters and numbers, probably defined like [0-9a-Z]{4,12}.
There are hundreds of such variables in the text. I need to know exact form of found string "variable" to use it in replacement. Is there a way to "remember" the string and use it later? Or any other method / software which could help in such case?
Thanks in advance.
If you could convert "variable" to uppercase by the way, it would be awesome.

如果将模式括在
\(...\)中，则可以使用模式中的内容进行替换。然后，您可以使用\1插入第一个此类括号捕获的内容。解决您的问题的一个简单的解决方案是：
You can use things in the pattern to replace with if you enclose it in
\(...\). You then use\1to insert the thing that was captured by the first such bracket.A naïve solution to your problem would be this:
