Default Adding an elements to existing xml document

I've gone over the code a million times, and I've even downloaded the code from this website and still can't seem to get it to work. Can anyone help me. The code is:
PHP Code:
  "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
  <head>
    <title>Adding an Element to an XML File with the DOM Extension</title>
    <link rel="stylesheet" type="text/css" href="common.css">
  </head>
  <body>
    <h1>Adding an Element to an XML File with the DOM Extension</h1>
    <pre>

<?php

// Load XML file
$doc = new DOMDocument();
$doc->preserveWhiteSpace false;
$doc->load"./stock_list.xml" );
$doc->formatOutput true;

// Get the stocklist root element
$stockListElements $doc->getElementsByTagName(  "stockList" );
$stockList $stockListElements->item);

// Create a new "item" element and add it to the stocklist
$item $doc->createElement"item" );
$item->setAttribute"type""vegetable" );
$stockList->appendChild$item );

// Create the item's "name" child element
$name $doc->createElement"name""carrot" );
$item->appendChild$name );

// Create the item's "unitprice " child element
$unitPrice $doc->createElement"unitPrice""0.79" );
$item->appendChild$unitPrice );

//Create item's quantity element
$quantity $doc->createElement"quantity""31" );
$item->appendChild$quantity );

// Create item's description element
$description $doc->createElement"description" );
$item->appendChild$description );
$cdata $doc->createCDATASection"Carrots are crunchy" );
$description->appendChild$cdata );

//Output the XML document, encoding markup characters as needed
echo htmlspecialchars$doc->saveXML() );

?>
      </pre>
    </body>
</html>
Thanks
