Description

SimpleXMLElement simplexml_element->children ( void )

This method finds the children of the element of which it is a member. The result follows normal iteration rules.

Nota: SimpleXML possiede regole per aggiungere proprietà iterative a diversi metodi. Queste non possono essere visualizzate con var_dump() o qualsiasi altra cosa che possa esaminare gli oggetti.

Esempio 1. Traversing a children() pseudo-array


<?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'];
        }
    }
}
?>

This script will output:

The person begot a son who begot a daughter; The person
begot a daughter who begot a son; and that son begot a son
