XML::LibXML Comment Class
This class provides all functions of XML::LibXML::Text, but for comment nodes. This can be done, since only the output of the nodetypes is different, but not the datastructure. :-)
new 	

$node = XML::LibXML::Comment( $content );

The constructor is the only provided function for this package. It is required, because libxml2 treats text nodes and comment nodes slightly differently.
