thealienz1 has asked for the wisdom of the Perl Monks concerning the following question:
I am currently working on a data mining algorithm program in Perl, which requires the need to read the arff file format. Currently, I have gotten as far as I can in a regular expression I am working on.
The regexp is being designed to load from the arff file the @attribute directive. Currently I am trying to implement the different possible formats of this into a single regexp.possible values

With the current output of the program being
As you can see the relation name for the Feature 0,1,2 are not being correctly read. I no I am so close, but it is getting late, and I have no idea where I am going with this regexp. I though I'd leave it open for the monks to tinker with.
