Regex for extracting digits in a random string

[Macro_Mitch]

Hello. Can someone please help how i can extract the only 4 digits available in a string eg:
1 "gajkd4ksks8nsh2hjs7ks"
2 "2jdjjd4jjsj7hsh3"
3 "Gsgs5926jsjd"
4 "HshhhdhklakkGhsh5277"
Note that the strings can be of different lengths and the digits might appear randomly in the string they don't follow a specific oder of appearance. I've tried the below regex (\d{4}) but it only works when the digits are placed together like in example 3. Thank you in advance

Try \d with the full match option in extract text option.

Any help in returning the sum of the extracted digits eg 6278 to be 6+2+7+8 which is 23

My previous suggestion only works for single digit numbers, i.e. from 0 to 9.

To be more versatile and extract whole numbers (not only digits) you could replace the Extract text AND the Replace text options by a unique Replace option with the following parameters:
- Source text: your source text with a mix of letters and digits
- Text to replace (regex): \D*(\d+)\D*
- New text: +$1

Unless you consider each digit is as whole number. Then a unique Replace text option with \D*(\d)\D* will make the job.

Then, as shown previously, set a numerical variable with the content of this new String variable...

Good luck!
