[英]regular expression with the same element twice without knowing it
I've plenty fill and want to find all of them which are like this:我有很多东西,想找到所有这样的:
A = A + B
So I wanna use a regular expression using M + x rgrep
.所以我想使用正则表达式使用
M + x rgrep
。 and was thinking to something like that: ([A-Za-z][A-Za-z0-9]*) = () + [A-Za-z][A-Za-z0-9]*
where ()
create a group which can be used latter.并且正在考虑类似的事情:
([A-Za-z][A-Za-z0-9]*) = () + [A-Za-z][A-Za-z0-9]*
其中()
创建一个以后可以使用的组。
Their is a way to make a regular expression where two item must be the same but without knowing the form of them?他们是一种制作正则表达式的方法,其中两个项目必须相同但不知道它们的形式?
