<?php

$xml = simplexml_load_string(

'<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'];

        }

    }
