用于包围包含字符串“;@tab;@tab;@tab;”的文本的正则表达式带引号

Question

我正在尝试创建一个 PCRE RegEx surrounds 字符串，其中包含字符串 ;@tab;@tab;@tab; 和引号 (").输入由多行文本组成，其中包含 1 个或多个用 制表符 分隔的列。必须用引号 (") 括起来的字符串可以位于行首、行尾或行中间。一行可以包含 0 个或更多必须包围的字符串。
示例：

1   some text with spaces
1   some text with spaces   anotherValue
1   some text with spaces   anotherValue    3452.2
val_so  some text with spaces   anotherValue    3452.2
val_so space    some text with spaces   anotherValue    3452.2
some text with spaces   anotherValue    3   other text with spaces

1   some;t@b;t@b;t@b;text;t@b;t@b;t@b;with tabs
1   some;t@b;t@b;t@b;text;t@b;t@b;t@b;with tabs and spaces  anotherValue
1   some;t@b;t@b;t@b;text;t@b;t@b;t@b;with spaces   anotherValue    3452.2
val_so  some;t@b;t@b;t@b;text with spaces and;t@b;t@b;t@b; tabs anotherValue    3452.2
val_so space    some text with;t@b;t@b;t@b; spaces amd tabs anotherValue    3452.2
some text;t@b;t@b;t@b; with spaces  anotherValue    3   other text;t@b;t@b;t@b;with spaces;t@b;t@b;t@b;and tabs
;t@b;t@b;t@b; with spaces   anotherValue    3   other text;t@b;t@b;t@b;with spaces;t@b;t@b;t@b;and tabs
;t@b;t@b;t@b;;t@b;t@b;t@b; with spaces  anotherValue    3   other text;t@b;t@b;t@b;with spaces;t@b;t@b;t@b;and tabs

必须变成

1   some text with spaces
1   some text with spaces   anotherValue
1   some text with spaces   anotherValue    3452.2
val_so  some text with spaces   anotherValue    3452.2
val_so space    some text with spaces   anotherValue    3452.2
some text with spaces   anotherValue    3   other text with spaces

1   "some;t@b;t@b;t@b;text;t@b;t@b;t@b;with tabs"
1   "some;t@b;t@b;t@b;text;t@b;t@b;t@b;with tabs and spaces"    anotherValue
1   "some;t@b;t@b;t@b;text;t@b;t@b;t@b;with spaces" anotherValue    3452.2
val_so  "some;t@b;t@b;t@b;text with spaces and;t@b;t@b;t@b; tabs"   anotherValue    3452.2
val_so space    "some text with;t@b;t@b;t@b; spaces amd tabs"   anotherValue    3452.2
"some text;t@b;t@b;t@b; with spaces"    anotherValue    3   "other text;t@b;t@b;t@b;with spaces;t@b;t@b;t@b;and tabs"
";t@b;t@b;t@b; with spaces" anotherValue    3   "other text;t@b;t@b;t@b;with spaces;t@b;t@b;t@b;and tabs"
";t@b;t@b;t@b;;t@b;t@b;t@b; with spaces"    anotherValue    3   "other text;t@b;t@b;t@b;with spaces;t@b;t@b;t@b;and tabs"

我尝试了以下 PCRE RegEx search RegEx: \b(([^\t]+);t@b;([^\t]+))\b with g flag replace RegEx: "" 但它匹配多行的字符串（匹配不会在行尾停止）但我希望每一行都单独匹配。

由于数据是用制表符分隔的，不想跨行，可以通过在取反符中加一个换行来排除匹配class.

您可以省略单词边界，因为它不会匹配 ; 开头和结尾的 ;t@b;t@b;t@b;

您不需要捕获组，因为您想要替换双引号之间的整个匹配项。

[^\t\r\n]+;t@b;[^\t\r\n]+

看到一个regex demo

在替换中使用双引号之间的整个匹配。

"[=11=]"
