Use Case

This macro uses a very specific RegEx in response to the requirements in this topic:
Extracting Text from URL

Most likely anyone else who wants to use this macro will need to change the RegEx to fit their needs.

However, this macro does illustrate an approach that can be used in general.

RegEx Solutions

USER CHOICE: Review these solutions and choose the one best for your use case.
Copy the RegEx expresstion and paste into the "Search Variable" Action.

FIRST SOLUTION -- See https://regex101.com/r/tyAOOA/1
Allow for any digit to precede the Capture Groups
This is the most flexible solution.


SECOND SOLUTION -- See https://regex101.com/r/X37oty/1
Requires specific numbers prior to the Capture Groups:
!3d AND !4d
This is the more reliable solution, assuming these specific numbers will always be in the URL.
