Bug description:SimpleXML doesn't like empty elements with attributes

Description:
------------
If the first XML element is an empty tag, e.g. <link term="no"/>, then no
elements by that name will get recognized. However, if you have many, e.g.
<link> elements, and you write at least the first one as a non-empty tag,
e.g. <link term="no"></link> SimpleXML will recognize all the elements
(even those with empty tags. A test program that uses a test file on my web
site shows this problem.

Test script:
---------------
$fn = "http://www.rajsingh.org/poiwg/c_error.xml";
$xml = simplexml_load_file($fn);

if ( !empty($xml->link) ) {
  echo "number of links: " . sizeof($xml->link) . "\n";
  foreach ($xml->link as $link) {
    echo "link href: " . $link['href'] . "\n";
  }
}

if ( !empty($xml->relationship) ) {
  echo "number of relationships: " . sizeof($xml->location->relationship) .
"\n";
  foreach ($xml->location->relationship as $rel) {
    echo "relationship term: " . $rel['term'] . "\n";
  }
}

Expected result:
----------------
number of links: 3
link href: http://www.rajsingh.org/pois/45343489.xml
link href: http://en.wikipedia.org/wiki/Boston
link href: http://www.geonames.org/maps/google_42.358_-71.06.html
number of relationships: 3
relationship term: contains
relationship term: within
relationship term: contains


Actual result:
--------------
number of links: 3
link href: http://www.rajsingh.org/pois/45343489.xml
link href: http://en.wikipedia.org/wiki/Boston
link href: http://www.geonames.org/maps/google_42.358_-71.06.html
