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.

> 注: 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.

範例 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
