Here is the HTML code to put on your website

include 'premium_programming_xml.class.php';

$p = new PremiumXML();
$xml = $p->xml_load_filename('sample.xml');

print_r($xml);

Here is sample.xml

<SampleXML>
	<Customer>
		<Name>Aaron</Name>
		<Position>Computer Programmer</Position>
	</Customer>
	<Customer>
		<Name>Phil Dunphy</Name>
		<Position>Real Estate Agent</Position>
		<MarriedTo>
			<Name>Claire Dunphy</Name>
		</MarriedTo>
	</Customer>
	<BusinessName>Your Company Name Here</BusinessName>
</SampleXML>

Here is the output

SimpleXMLObject Object
(
    [Customer] => Array
        (
            [0] => SimpleXMLObject Object
                (

/* This code was written by Aaron Jay Lieberman on 11/13/10 
This class creates a SimpleXML object for an XML string.  It assumes simple 
XML formatting and was written to overcome large XML string sizes.
It is a replacement for simplexml_load_string for PHP4 and 
doesn't use any PHP XML classes
