如何使用正则表达式替换标签内 csv 的双引号

Question

我有一个 csv 文件，它在标签中包含双引号并用双引号括起来。需要用其他字符替换标签内的双引号。例如

"id"|"Name"|"Note"
"1"|"Sam"|"<Note> This is "a" Sample </Note>"
"2"|"Sam1"|"<Note> This "is "a" Sam"ple "</Note>"

期望的输出

"id"|"Name"|"Note"
"1"|"Sam"|"<Note> This is a Sample </Note>"
"2"|"Sam1"|"<Note> This is a Sample </Note>"

Answer 1

这里有一个方法：

Ctrl+H
查找内容：(?:<Note>|\G(?!^))(?:(?!</Note)[^"])*\K"(?=.*</Note>)
替换为：LEAVE EMPTY
检查 匹配大小写
检查环绕
检查 正则表达式
取消选中 . matches newline
全部替换

解释：

(?:                 # non capture group
    <Note>              # literally, open tag
  |                   # OR
    \G(?!^)             # restart from last match position except beginning of line
)                   # end group
(?:                 # non capture group
    (?!                 # negative lookahead, make sure we haven't after:
        </Note              # literally close tag
    )                   # end lookahead
    [^"]                # any character that is not a double quote    
)*                  # end group, may appear 0 or more times
\K                  # forget all we have seen until this position
"                   # double quote
(?=.*</Note>)       # positive lookahead, make sure we have close tag after
