-w is kind of pan-galactic and influences modules you're calling, regardless of their own 'warnings' settings. Try 'use warnings' without -w. See p861 in the camel 3rd edition.

I'm messing with XML & MySQL, and I may have run into a newbie snag. I'm using XML::Generator ::DBI with XML::Handler::YAWriter, in the same manner that I've seen in tutorials, the MySQL Cookbook, and other assorted places. > $writer = XML::Handler::YAWriter->new (AsString => 1); $query = > 'SELECT cd_airdate, cd_copies, cd_hilites FROM cds WHERE cd_labeled=0 > ORDER BY cd_airdate'; > $generator = XML::Generator::DBI->new( dbh =>$dbh, > Handler =>$writer, > RootElement=>"Creators", > Indent=>1, > QueryElement => ''); > $xml_output = $generator->execute($query); According to the XML::Gen perldoc, "Nulls are handled by excluding either the attribute or the tag." The XML looks and works just fine. No prob. However,when I use the -w option with the shebang, I get a couple warnings for each record of the database. They're all about the same: "Use of uninitialized value in string eq at /Library/Perl/5.8.1/XML/Generator/ DBI.pm line 180." Now it seems to me that if nulls are supposed to be handled by the modules, then why the warnings? Is it normal for modules to put out warnings during their normal function? I'm used to C/C++ environments where you normally eliminate any warning that appears.
