NAMESPACES

    A true (1) or false (0, undef) value; if this parameter is present and its value is true, then the module will accept two-member array reference in the place of element and attribute names, as in the following example:

      my $rdfns = "http://www.w3.org/1999/02/22-rdf-syntax-ns#";
      my $writer = new XML::Writer(NAMESPACES => 1);
      $writer->startTag([$rdfns, "Description"]);

    The first member of the array is a namespace URI, and the second part is the local part of a qualified name. The module will automatically generate appropriate namespace declarations and will replace the URI part with a prefix.

my $rdfns = "http://www.w3.org/1999/02/22-rdf-syntax-ns#";
my $writer = new XML::Writer(OUTPUT => \$output, NAMESPACES => 1);
$writer->startTag([$rdfns, "Description"]);
$writer->startTag("greeting",
                  "class" => "simple");
$writer->characters("Hello, world!");
$writer->endTag("greeting");
$writer->endTag("Description");
$writer->end();
print $output;
