How do I serve an XML file as a web service in PHP?

[fredramsey]

I would like to have a web service in PHP simply send an existing XML file - this is to get around the cross-site XMLHttpRequest limitation. I need to read it in JavaScript on the client end.

Can this be done?

I am a PHP n00b, so any code example some kind soul can provide would be greatly appreciated.

All you need is to set your header for XML content and then output pure XML.

<?php
header ("Content-Type: text/xml");

echo $xmlContent;
?>

That's cool, but I think you're still limited by JavaScript's inability to read a file located on another server. I was really looking to make it into a Web Service I can call.

Thanks, though, I did learn something.

You misunderstand JavaScript's cross-domain policy. JavaScript can read files on other domains...it cannot interact with DOM elements on other domains.
