The root of a document cannot be a comment, however you can add a comment with
$dom->addChild($dom->createComment(‘test comment’))
#!/usr/bin/perl
use strict;
use warnings;
use XML::LibXML;
my $doc = XML::LibXML::Document->new(qw/1.0 utf-8/);
$doc->appendChild($doc->createComment('test comment'));
$doc->setDocumentElement(my $e_products = $doc->createElement('products'));
$e_products->appendTextChild(field => 'testing');
print $doc->toString(1);
