Note: the "Perl and DB" slides (set 4) has an error on page 5, the second slide 
entitled "Example -- Get from DB, output TEXT".    The error does not matter much 
for producing text, but could cause problems when having Perl generate XML.  

Corection -- to have Perl generate a text file (such as CSV format), you should *not*
have: 
   print header("Content-Type: text/plain; charset=UTF-8");
instead use this:  
  print "Content-Type: text/plain; charset=UTF-8\n\n";

(the \n\n is necessary to insert a blank line after the header).

If you want to produce XML, change text/plain to text/xml. Here is a complete Perl file that 
generates simple XML.

use CGI qw( :standard );
use DBI;
use DBD::mysql;
use strict;

print "Content-type: text/xml; charset=UTF-8\n\n";

print "<person>\n";
print "  <fname> Joe </fname>";
print "  <lname> Mid </lname>";
print "</person>\n";
