SimpleXMLElement->children() --
Finds children of given node
Description
class
SimpleXMLElement {
SimpleXMLElement
children ( [string ns [, bool is_prefix]] )
}
This method finds the children of the element of which it is a member. The result
follows normal iteration rules.
Note: SimpleXML has made a rule of adding
iterative properties to most methods. They cannot be viewed using var_dump()
or anything else which can examine objects.
Example 1. Traversing a children() pseudo-array
<?php
$xml = new SimpleXMLElement(
'<person>
<child role="son">
<child role="daughter"/>
</child>
<child role="daughter">
<child role="son">
<child role="son"/>
</child>
</child>
</person>');
foreach ($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 |
