Get all parent terms for a specific node

Oh I ended up solving this with a custom module, sorry should have closed it.

I just re-read my post and realized the formatting was lost which probably didn't help any lack of replies for over a month!

Never mind, thanks for the interest to help!

I just made a custom module which provides a function which I'm using at the theme level to take the nid and then output the term parents of a hardcoded taxonomy ID. My code is not reusable unless you're prepared to modify it, but here it is:

In the theme ($output is the nid supplied by a view field):

$sectionArray=_taxonomy_get_sections($output);
$sectionLinks=array();
foreach($sectionArray as $tid => $section){
  $sectionLinks[]=l($section,"taxonomy/term/$tid");
}
print implode(', ',$sectionLinks);

In the custom module:

function _taxonomy_get_sections($nid){
$sectionArray=array();
  if(is_numeric($nid)){
    $sql="
      SELECT DISTINCT
        td_sec.name,
        td_sec.tid
      FROM term_data td_cat
      JOIN term_node tn_cat
        ON td_cat.tid=tn_cat.tid
      JOIN term_hierarchy th_cat
        ON tn_cat.tid=th_cat.tid
      JOIN term_data td_sec                                                                                                                        
        ON th_cat.parent=td_sec.tid
      WHERE
        nid=$nid
        AND td_cat.vid=1
    ";
    if($query=db_query($sql)){
      while($result=db_fetch_object($query)){
        $sectionArray[$result->tid]=$result->name;
      }
    }
  }
  return $sectionArray;
}
