'<person>
<child role="son">
 <child role="daughter"/>
</child>
<child role="daughter">
 <child role="son">
  <child role="son"/>
 </child>
</child>
</person>');

foreach ($xml->children() as $second_gen) {
   echo ' The person begot a ' . $second_gen['role'];

   foreach ($second_gen->children() as $third_gen) {
       echo ' who begot a ' . $third_gen['role'] . ';';

       foreach ($third_gen->children() as $fourth_gen) {
           echo ' and that ' . $third_gen['role'] .
               ' begot a ' . $fourth_gen['role'];
