Question

我有这样的文字：

something text
(some text here image and more text)
some more text
(test)
text

我想对2个括号之间的所有内容进行正则表达式搜索并搜索单词image，如果该单词存在于2个括号之间，那么我想在该行之后添加一个新行。所以我的正则表达式应该产生这个输出：

something text
(some text here image and more text)

some more text
(test)
text

我怎样才能做到最好？我已经尝试了(?<=$)(?=image)(?=$)但是没有用。

Answer 1

使用单词边界：

\(.*\bimage\b.*\)

要在匹配时捕获该模式，请将其放在括号内：

(\(.*\bimage\b.*\))

然后尝试使用$1（或\1引用该组，具体取决于正在使用正则表达式的语言。）

Answer 2

您可以使用以下正则表达式在括号中搜索单词image，并将其替换为捕获的组和新行，您可以获得预期结果：

(\(.*?image.*?\))

input        >>  something text
                 (some text here image and more text)
                 some more text
                 (test)
                 text
regex search >>  (\(.*?image.*?\))
replace with >>  `$1\n`
output       >>  something text
                 (some text here image and more text)

                 some more text
                 (test)
                 text

您没有提及工具，但使用sed 's/(.*image.*)/&\n/' file

\b

如果你想限制独立单词“image”使用sed 's/(.*\bimage\b.*)/&\n/' file单词边界（我认为只有GNU sed）
