正则表达式 - 与和运算符匹配的行

I have some text:

我有一些文字：

The great red fox. Which are not blue foxes. But foxes which are red are not any more faster.

伟大的红狐狸。这不是蓝狐。但是红色的狐狸不再快。

Basically I want to match sentences where "red" and "fox" both appear in that order and another regex where it is not in that order.

基本上我想匹配“红色”和“狐狸”都以该顺序出现的句子和另一个不按顺序出现的正则表达式。

How would I do that ?

我该怎么办？

3 个解决方案

#1

Assuming that there is no abbreviations with dots in your sentences:

假设句子中没有带点的缩写：

for any order:

对于任何订单：

(?=[^.!?]*fox)(?=[^.!?]*red)[^.!?]+[.!?]

for "red" before "fox":

对于“狐狸”之前的“红色”：

[^.!?]*?red[^.!?]+?fox[^.!?]*[.!?]

#2

For "red" following "fox":

对于“狐狸”之后的“红色”：

\b[^.?!]+red.*?fox[.?!]+

for "fox" following "red":

对于“红色”之后的“狐狸”：

\b[^.?!]+fox.*?red[.?!]+

to capture all other sentences except ones have "red" following "fox":

捕获所有其他句子，除了“狐狸”之后的“红色”：

(?:\b[^.?!]+red.*?fox[.?!]+)(.*?[.?!]+)

as you work with Javascript don't forget to put g modifier to capture all occurrences:

当您使用Javascript时，不要忘记使用g修饰符来捕获所有出现的内容：

/\b[^.?!]+red.*?fox[.?!]+/g

#3

Assuming each sentence appears in a separate line you can do:

假设每个句子出现在一个单独的行中，您可以这样做：

I want to match sentences where "red", "fox" both appears in that order

我想匹配“红色”，“狐狸”都按此顺序出现的句子

You can use:

您可以使用：

^.*?red.*?fox.*$

I want to match sentences where "red", "fox" both appears in ANY order

我希望匹配“红色”，“狐狸”都以任何顺序出现的句子

You can use positive lookahead:

你可以使用积极的前瞻：

^(?=.*?red)(?=.*?fox).*$
