PHP - Handling XML

To handle xml document using php, here's a bit of code of it:
For example, you have an xml document:

<?php

$xml = '<?xml version="1.0"?>';

$xml .= '<data>';

$xml .= '<name>Luna Maya</name>';

$xml .= '<city>Denpasar</city>';

$xml .= '<age>27</age>';

$xml .= '</data>';

$xmlDoc = new DOMDocument();

// if the xml document lies on the file, use $xmlDoc->load('your_file.xml');

$xmlDoc->loadXML($xml);

$name = $xmlDoc->getElementsByTagName('name');

echo $name->item(0)->nodeValue;
