This is happens at the very end of the script. The only printing I do. 
print CGI->header('text/xml');
print "<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?>\n";
print "<dataset>\n";
print @output;
print "</dataset>";
exit;

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
