in reply to Parsing multi-line record with varying data
If you use something like "\nrn" as input record separator (assigning this string to the $/ variable), you will be able to work with each group of lines in paragraph mode. Then, you only need to count the number of occurrences of "id-info" in each record (one way to do it is to use the s/// function on the id-info pattern in scalar context, as it will return the number of substitutions made). I will not elaborate more for the time being since you are not showing real input data nor really detailing the output you need.
Update 23:06 UTC: Oops, I did not see that's basically the solution proposed by NetWallah, whose code I had not tried to read before posting.
