Regex: Mix-Numbers / Cross-numbers

[Vasile Caraus]

hello, I need a regex to mix numbers on different lines and columns. So, I try to use the regex that guy38 used to mix words on other topic: https://notepad-plus-plus.org/community/topic/12322/regex-crossword-maker-mix-words

For example this .txt files with numbers:

15 34 39 42 43 48
36 5 13 9 6 17
2 18 20 34 32 3
10 29 18 2 39 44

So, this is guy38 regex for mix words:

SEARCH : ([\w-]+)[^\w\r\n-]+([\w-]+)[^\w\r\n-]+([\w-]+)[^\w\r\n-]+([\w-]+)[^\w\r\n-]+([\w-]+)[^\w\r\n-]+([\w-]+)[^\w\r\n-]+([\w-]+)

REPLACE : \3 \1 \7 \5 \4 \2 \6

Now, I try wo change a little bit his search part, instead of \w I will try to use \d :

([\d-]+)[^\d\r\n-]+([\d-]+)[^\d\r\n-]+([\d-]+)[^\d\r\n-]+([\d-]+)[^\d\r\n-]+([\d-]+)[^\d\r\n-]+([\d-]+)[^\d\r\n-]+([\d-]+)

It doesn’t work. Anyone?
