I've been trying to see some way to achieve the following:
From the input:
lorem d5, ipsum, asd ffs: 5455, 45454, 232334, 23234.
Select by 1 single regular expression all commas (only commas) that are preceded by a number from the text that follows after the text "asd ff":
I have tried several ways with the lookbehind but I can only fulfill one of the two conditions at a time, is there any other way to achieve it?
It is not possible with a regular expression, since you need to use repeating groups and these only match the last iteration, so you would first have to get the text part after "asd ff" and to that string apply the expression that match a comma.
To select each comma after "asd ff" with a single expression, you would have to repeat the pattern N times within the regular expression but this is not practical at all
