我有一个datebase文本文件，值用“，”分隔

2214，Bunny_Band，Bunny Band，4,20，，100 ,, 2 ,, 0,0xFFFFFFFF，7,2， 1024 ,, 0,1,15 ，{}，​​{}，{}

然后将第9个值更改为0，第15个值为1024

Answer 1

• Ctrl + H
• 查找内容：^(?:[^,]*,){8}\K[^,]*(?=(?:,[^,]*){5},1024,)
• 替换为：0
• 检查 环绕
• 检查 正则表达式
• 全部替换

说明：

^                   # beginning of line
  (?:[^,]*,){8}     # non capture group, 0 or more non comma followed by comma, must appear 8 times
  \K                # forget all we have seen until this position
  [^,]*             # 0 or more non comma
  (?=               # positive lookahead, make sure we have after:
    (?:,[^,]*){5}       # 5 times a comma followed by 0 or more non comma
    ,1024,              # number 1024 surounded by comma
  )                 # end lookahead
