So you have the data, and all you need to do is display it in a webpage. The only thing you really need to do is to write out a valid html page to STDOUT - you'll need to enclose your data in or between valid html tags. Not sure what your data looks like, but standard perl module CGI.pm might be the easiest solution for you. CGI.pm has been around for a long time - it makes writing a valid html page a fairly trivial exercise. Do
perldoc CGI
at a command prompt to see read the documentation included with the CGI.pm module. Or browse to http://stein.cshl.org/WWW/software/CGI/ to read Lincoln Stein's documentation on CGI.pm.
HTH.
