If you're facing problems on Windows Servers running PHP 5.3 and newer, where this function quits with an "Unable to resolve file path" Error, here is a Workaround which isn't posted on the Bug site yet:

Add this before you use the openURI()-function:

<?php
touch($uri);
$uri = realpath($uri);
?>

This Bug appears in the following cases:

$xml->openURI('file.xml'); -> ok!
$xml->openURI('../file.xml'); -> ok!
$xml->openURI('xml/file.xml'); -> DON'T WORK!
$xml->openURI('../xml/file.xml'); -> DON'T WORK!

I wanted to stream a XML file directly to the user and having him prompted to save it without displaying the content, but when using

<?php
$out =new XMLWriter();
$out->openURI('php://output');
?>

the user's browser was displaying the file contents instead of prompting the user with a filesave window.

To have the XML file stream saved directly to the user without being displayed by the browser, you shoud add:

<?php
header("Content-Type: text/html/force-download");
header("Content-Disposition: attachment; filename='file_name.xml'");
$out =new XMLWriter();
$out->openURI('php://output');
?>

This will prompt the user with a dialog box to save 'file_name.xml' on his disk, and will not display the content of the streamed XML.

Want to write xml-data directly to the user instead of memory or file?
This will do:
<?php
$out =new XMLWriter();
$out->openURI('php://output');
?>
