Question

我正在尝试使用sublime

修复带正则表达式的文本文件

文本包含

的实例

.. "description": "some description", "address": "some address", ...

由于某种原因，我的实例看起来像

.. "description": "some description", "some address", ...

所以我想找到那些有问题的并插入"address":。

我试图用

的负向前瞻来做这件事

\"description\":\s*\".*?\"\,\s*(?!\"address\"\:)

但它会找到每个实例，而不仅仅是description后面没有address

我做错了什么？

Answer 1

你的模式的问题是在负面向前看之前的最后\s*抛出模式，试试这个

(\"description\":\s*\"[^"]*\"\,)(?!\s?\"address\"\:)

并替换为$1"address":

(                   Capturing Group \1
  \"                """
  description           "description"
  \"                """
  :                 ":"
  \s                <whitespace character>
  *                 (zero or more)(greedy)
  \"                """
  [^"]              Character not in [^"]
  *                 (zero or more)(greedy)
  \"                """
  \,                ","
)                   End of Capturing Group \1
(?!                 Negative Look-Ahead
  \s                <whitespace character>
  ?                 (zero or one)(greedy)
  \"                """
  address               "address"
  \"                """
  \:                ":"
)                   End of Negative Look-Ahead

Answer 2

您可以搜索此正则表达式：

("description":\s*"[^"]*\"\s*,\s*")(?!address")([^"]*".*$)

并替换为：

$1address": "$2

否定前瞻不起作用
