Parse XML med PHP

jeg har følgende:

Det jeg vil parse ligger her:
http://news.php.net/group.php?group=php.announce&format=rss

Der kommer noget men ikke den sidste echo tabel

*************FEJL*******
$counting=count($xmlC->obj_data->CHANNEL[0]->ITEM); //to find out the number of elements in the array
$IPADDR="";
$OWNER="";
$PUB="";
$DESC="";

for($i=0;$i<$counting;++$i)
  {
      $IPADDR[$i]=$xmlC->obj_data->CHANNEL[0]->ITEM[$i]->LINK[0];
      $OWNER[$i]=$xmlC->obj_data->CHANNEL[0]->ITEM[$i]->TITLE[0];
      $DESC[$i]=$xmlC->obj_data->CHANNEL[0]->ITEM[$i]->DESCRIPTION[0];
      $PUB[$i]=$xmlC->obj_data->CHANNEL[0]->ITEM[$i]->PUBDATE[0];
      }
  echo("<center><TABLE border=1>");
  for($i=0;$i<$counting;++$i)
    { echo "<tr><td>$IPADDR[$i]</td><td>$OWNER[$i]  $DESC[$i] $PUB[$i]</td></tr>"; }
  echo("</TABLE></center>");
