Printing XML error

[NZ_Kiwis]

I have this script to make me an XML file, here is the link http://www.rugbyleaguenz.com/app/userlist.php
As you can see it does not work as such, it does display a page in firefox and when i view the source it's all there but why does it not display normally????

<?php

// THIS IS ABSOLUTELY ESSENTIAL - DO NOT FORGET TO SET THIS
@date_default_timezone_set("GMT");

$writer = new XMLWriter();
// Output directly to the user

$writer->openURI('php://output');
$writer->startDocument('1.0');

$writer->setIndent(4);

// declare it as an rss document
$writer->startElement('rss');
$writer->writeAttribute('version', '2.0');
$writer->writeAttribute('xmlns:atom', 'http://www.w3.org/2005/Atom'); 



$writer->startElement("channel");
//----------------------------------------------------
//$writer->writeElement('ttl', '0');
$writer->writeElement('title', 'Members List');
$writer->writeElement('description', 'A list of all members plus their details.');
$writer->writeElement('link', 'http://www.***.com');
$writer->writeElement('pubDate', date("D, d M Y H:i:s e"));
//----------------------------------------------------

mysql_connect (localhost, **, **);
mysql_select_db (**);

//----------------------------------------------------
$result = mysql_query ("SELECT * FROM members limit 10"); 
WHILE ($row = mysql_fetch_array($result)) { 
$username = $row['username'];
$level = $row['level'];
$password = md5($row['password']);

$writer->startElement("User");
$writer->writeElement('Username', $username);
//$writer->writeElement('Password', $password);
$writer->writeElement('Level', $level);

// End Item
$writer->endElement();

}
//----------------------------------------------------


// End channel
$writer->endElement();

// End rss
$writer->endElement();

$writer->endDocument();

$writer->flush();
?>

I suspect the problem is that your output is specifying that it is RSS/Atom, but there is no <User> element in the Atom specification, so they are being ignored in the browser's display of the file.

You are right, how can I get around this? is there a list of elements in the Atom specification anywhere

Hold on it does not work.....

$writer->startElement("item");
$writer->writeElement('description', $username);
$writer->writeElement('description', $password);
$writer->writeElement('guid', $level);

// End Item
$writer->endElement();

Same link for the output...

yet if i copy and paste the code to a XML file it works okay

Try adding a header() before anything is output:

header('Content-Type: text/xml');
