Parsing XML in PHP

To parse XML easily in PHP, I recommend you to use SimpleXML extension. The below is the sample reference to use SimpleXML extension.

<?php

// this is a sample xml string

$xml_string="<?xml version='1.0'?>
<moleculedb>
	<molecule name='Benzine'>
		<symbol>ben</symbol>
		<code>A</code>
	</molecule>
	<molecule name='Water'>
		<symbol>h2o</symbol>
		<code>K</code>
	</molecule>
</moleculedb>";

// load the xml string using simplexml function
$xml = simplexml_load_string($xml_string);

//loop through the each node of molecule
foreach ($xml->molecule as $record)
{
	// attribute are accessted by
	echo $record['name'], '  ';

	// node are accessted by -> operator
	echo $record->symbol, '  ';
	echo $record->code, '<br />';
}
