How to ignore white space with regex?

Here is my regex:

^(SK{1}[0-9]{8})$

But I want text like this:

SK 283 92758
SK 283 92 7 58

to be taken as this:

SK28392758

It is possible?

If you want to remove any whitespaces use [^\s].

See the demo here: https://regex101.com/r/a1kojC/1

Use the "optional" quantifier ? for a space between each character:

^S ?K ?(\d ?){7}\d$

This allows an optional space between the characters.
To allow any number of spaces, replace every ? with *.

See live demo.

I also removed unnecessary brackets:

  • {1} is pointless
  • the brackets around the whole thing are unecessary; group 0, which is the whole match, is always available is you absolutely need a capture group

You can use the regex ^(SK{1}\s\d{3}\s\d{5})$ and use a String.Replace afterwards to remove the spaces.
