because you have used parent::node() (which could more simply be written 
as ..) rather than parent::* then if it doesn't find the $node-id it 
will reach / and then (because your template only matches * not /) it 
will apply the default template to / which will apply templates to its 
element child, hitting this template again and looping forever. 
cahanging the match to "*|/" should fix it.
