I tried to use unlink_node to delete a node, but it never worked.
However, you can delete a node with this:

function delNode($node){
                   $nud=$node->parent_node();
                   $nud->remove_child($node);
}

Just like dump_node*, this method requres the node as an argument.
Like this:
      $removeThis = $dom->get_element_by_id ('26');
      $unlinked = $removeThis->unlink_node($removeThis);

In the example above, $unlinked seems to be NULL.

I'm using 4.3.0-dev (build: Nov 14 2002 10:13:12) in Module mode on Apache/1.3.24 - Win2000.
