$xml = simplexml_load_string($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"; } ?>
