在notepad ++中使用正则表达式查找和替换变量数字

Question

I need to replace 16.16.XXX"> with 16.16.XXXA"> , where X represents any digit, using notepad++'s find and replace feature. I just need to add the A but keep the other numbers (the last three digits represented by X are variable).

I know little about regexes, but I tried entering 16.16.\\d\\d\\d"> in the "find" field and tried to replace it with 16.16.\\d\\d\\dA"> , but this replaced the variable digits with \\d\\d\\d rather than their original digits.

Answer 1

Use

Find what : (16\\.16\\.\\d{3})(">)
Replace with : $1A$2

Details

• (16\\.16\\.\\d{3}) - Group 1: 16.16. and any 3 digits ( \\d{3} )
• (">) - Group 2: "> substring.

The $1 and $2 are backreferences that refer to the values captured with the corresponding capturing groups.
