1231286234|453|1234|xxx aabbc|xcvxcvxcv|xcvxcvxcv|Xcvxcvxcv

Answer 1

这适用于您提供的示例。

Find what: (\w*\|\w*\|\w*\|\w*)([\|\s]*)([\w\|]*)
Replace with: \1 \3

Search mode: Regular expression

Answer 2

• Ctrl+H
• 找什么：^(?:[^|]+\|){3}.*?\K\h*\|\h*
• 替换为： <-- 一个空格
• 查看 环绕
• 查看 正则表达式
• 取消选中 . matches newline
• Replace all

解释：

^               # beginning of line
  (?:           # start non capture group
    [^|]+       # 1 or more non pipe
    \|          # a pipe, have to be escaped as it's special character for regex
  ){3}          # end group, must appear 3 times
  .*?           # 0 or more any character but new line, not greeedy
  \K            # forget all we have seen until this position
  \h*           # 0 or more horizontal spaces
  \|            # a pipe, have to be escaped as it's special character for regex
  \h*           # 0 or more horizontal spaces
