XML is a markup language that looks a lot like HTML.

XML is very strict when it comes to document structure.

HTML list that is valid XML

<ui>
<li>code now</li>
<li>code always</li>

Parsing an XML Document

It turns an XML document into an object that provides structured access to the XML.

<?php
$myXMLData =
"<?xml version='1.0' encoding='UTF-8'?>

<note>
   <to>Mr. Mark john</to>
   <from>Lara Mosh</from>
   <heading>Assignment Submission</heading>
   <body>PHP XML Tutorials  </body>
</note>

XML;
$xml=simplexml_load_string($note);
print_r($xml);
?>

This will produce the following result −

Result :

SimpleXMLElement Object ( [to] => Mr. Mark john [from] => Lara Mosh [heading] => Assignment Submission [body] => PHP XML Tutorials )
