Generate xml to download

Question

Hello,
With an APEX application I need to generate an xml file to download to users computer.
The file should look like that:
<?xml version="1.0" encoding="UTF-16"?>
<flashmedialiveencoder_profile>

How could I achieve this so that the xml file would be downloadable from a link or a button?
What I have done so far is this:
-- Set the MIME type
owa_util.mime_header( 'text/xml', FALSE );
-- Set the name of the file
htp.p('Content-Disposition: attachment; filename="test.xml"');
-- Close the HTTP Header
owa_util.http_header_close;
htp.p('<?xml version="1.0" encoding="UTF-16"?>

-- Send an error code so that the
-- rest of the HTML does not render
htmldb_application.g_unrecoverable_error := true;
This gives me a file, but it does not work. I need to use the file as a profile for Flash Media Live Encoder (http://www.adobe.com/products/flashmediaserver/flashmediaencoder/). After donloading this file it says that the file is not good for the encoder.
I really do hope that you can help.

Hello,
Try your htp.p without the <?xml version="1.0" encoding="UTF-16"?>
That should get added automatically when you call owa_util.mime_header
