Leverage regular expressions to extract numbers preceding the final matched instance

Within my string of logs, I have the following:

rgb(255, 255, 255) 0px 0px 0px 16px inset

I am interested in extracting the dynamic value, which in this case is 16. How can I create a regex pattern that will capture the last instance of px, and then retrieve the digits between px and the space?

Answer №1

Considering you specifically requested the number prior to the final instance of px, I will refrain from assuming the presence of the term inset. In my opinion, utilizing \b\d+(?=px\b(?!.*\b\d+px\b)) would likely be your optimal choice in this scenario.
