How to strip out numeric characters only from a string

Hi, I have a string of “Please bill 28kg” or sometimes “Bill 28lbs” or many more potential type of string that I would receive. So now the question is how do I just strip out the numeric characters only from the string. Example: String - “Bill 28kg” Expecting outcome - “28” Do anyone have any idea how to do this? I’ve tried Regex, but not sure how to do it as the output is in list of array.

Should answer it for you

From there you just use .length to get the length of what you extract
