Retrieve sequence number of a string from right hand side with Regular Expressions

[SirAlonne]

Hi!
I've been experimenting for a while with this but it seems I stuck in a wall or missing something..
So let's say i have a string and I want an unknown length sequence number (in this case the 11) so I used:

Local $String = "john.wick.cv. 2019.russian 666_roulette 11.pdf"
StringRegExpReplace($String, "^.*\h|D", "", Default)
; This retrieved "11"

BUT if the filename changes "john.wick.cv.2019.russian 666_roulette11.pdf"  because a retarted user accidentally forgot to put space before the number, then the previous method does not works.. Is there a way to retrieve the sequence with regular expressions starting from right hand side?

To summarize it more briefly:

• The filename could be anything
• The sequence number always at the end of the filename followed by the dot and the extension
• The sequence number could be any length (\d+)
• The filetype is a set of extensions (.pdf .psd .ai .blend)

Try this

StringRegExpReplace($String, ".*\D(\d+).*", "$1")

Nice mikell, but I would change to  ".*\D(\d+)\..*" in case there is a number in the extension (ex.au3)

Thanks @mikell and @Nine !
I just solved it right after sending the post but it seems mine is a bit too complicated..

$String = StringRegExpReplace($String, "(?i).*?((\d+)(\.)(\b(pdf)\b|\b(psd)\b|\b(ai)\b|\b(blend)\b)).*?$", "$1")
$String = StringRegExpReplace($String, "\D", "")

oh, we can complicate things

Local $String = "john.wick.cv. 2019.russian 666_roulette5711.pdf"

msgbox(0, '' , stringreverse(number(stringreverse(stringmid($String , 1 , stringinstr($String , "." , 0 , -1) - 1)))))

StringRegExpReplace($String, ".*?(\d+)\.(?:pdf|psd|blend)$", "$1")

Absolutely right... but as usual I strictly followed the requirements mentioned in post #1
