Hi Monks;

I am hoping that you might be able to help me with something with which I am having trouble even figuring out where to start. I have a file that has a column in it of the following form:

Category1

Category1--Subcategory1--subsubcategory1--etc.

Category1--Subcategory1--subsubcategory2--etc.

Category1--Subcategory2--subsubcategory1--etc.

Category1--Subcategory2--subsubcategory2--etc.

Category2

Category2--Subcategory1--subsubcategory1--etc.

Category2--Subcategory2--subsubcategory1--etc.

What I would like to do is create an index that would number each category and subcategory within it. So according to the info above, it would look something like this:

1

1.1.1

1.1.2

1.2.1

1.2.2

2

2.1.1

2.2.1

I don't have much yet in the way of code because I'm not sure which way would be best to incriment each time there was a change. I was thinking separating hashes based on the main category but I still am unsure how that would work out. Does anyone have any suggestions? Any help would be greatly appreciated.

Here's How I've started my code anyway:

#!/usr/bin/perl -w

use strict;

open (IN, "C:/Work/start_file.txt");
open (OUT, ">C:/Work/finish_file.txt");
     
     while (<IN>){
            chomp;
           
           my @t=split(/\t/);
           
           my @categories=split(/--/,$t[0]);
           

           
           }
           
close OUT;
close IN;
