Output XML to Internet Explorer using PHP??

[Whysman]

Is there a way Internet Explorer can interpret PHP output as an XML file?

I know how to create a DomDoc using PHP, but when I output the document to the browser, Internet Explorer always interprets the data tree as text/html rather than giving me the usual XML collapsable tree view one gets when directly opening a filename.xml

Don't forget the header("Content-Type: text/xml"); so that the browser knows how to interpret what it's getting.
