Searching with recursion

[JKwan]

LSD is a location format with Oil and Gas sector
I use dashes for visibility
Union - I would like to capture all the Asset Numbers for every match

Yes, I know this may turn out to be a spider web.... I am doing this as a test and see where it will take me.
The chain will stop when the From = To or that the list is exhausted.
