 </b>
 <d>
  <c>code</c>
 </d>
</a>
XML;

$xml = new SimpleXMLElement($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";
}
?>

/a/b/c: text
/a/b/c: stuff
b/c: text
b/c: stuff

Notice that the two results are equal.
