Parse flat file and display in expandable tree

Hi all,
I haven't written code in a while and was hoping someone here might be able to help. In theory it seems pretty simply but I am not sure of the syntax.

I need to parse a data text file which natively in this format:

CORP,101,90210-sf101,aggregate2.402:1,10.1.1.100/27,402

Next I need to display it, delimited and in tables.

Ideally I plan to include an expansion tree table so that all data of the same type (CORP) will have a heading that can be expanded to reveal all data under that heading.

How do I start? What is the proper syntax to do this in CGI/Perl?

Thanks for the help.Start Free Trial
