$xml = new SimpleXMLElement($string);

/* Search for <a><b><c> */
$result = $xml->xpath('/a/b/c');

while(list( ,
$node) = each($result)) {
    echo
'/a/b/c: ',$node,"\n";
}

/* Relative paths also work... */
$result = $xml->xpath('b/c');

while(list( ,
$node) = each($result)) {
    echo
'b/c: ',$node,"\n";
