PHPStorm Regex用回叫替换

Question

I want to use PHPStorm to find and replace all instances of:

[A-z]['][s]

---

Example:

Andy's or David's

to:

Andy\\'s or David\\'s

I have the regex as above, but I want to know how to use the found character in the regex in the replace.

Answer 1

There are several problems with the regex the way you have it: [Az]['][s]

You can't use a shortcut [Az] to get a range of all upper and lower. You need to use [A-Za-z] . You also don't need the apostrophe and s in brackets:

[A-Za-z]'s

Then, to replace with a matched group, use $ groups:

([A-Za-z])'s , replacing with $01\\\\\\\\'s

Answer 2

The $ character is used to access the array of regex groups.

The regex groups can be defined with brackets.

This works:

Find: ([Az/0-9])['][s]

Replace: $01\\\\\\\\'s

(To print one slash, 4 are needed.)
