Can you arrange for the text group you want passed to your program to be
passed via the URI used to access your program?  For instance, if someone
clicks a link in the page that contains "Files (12)" that points to this:

    http://example.com/cgi/your_script.rb

=2E . . can you arrange for it to send this instead?

    http://example.com/cgi/your_script.rb?myfiles=3DFiles (12)

If so, you can use the Ruby/CGI library to parse that:

    require 'cgi'
    cgi =3D CGI.new

    myfiles =3D cgi['myfiles']

(code untested, dredged from memory; hopefully it would work as written)
