I am completely baffled with xml, I dare admit it.
I've looked at tutorials for xml and xsl(i think it's called that), but I fail to see any difference between that and say xhtml and using html markup.
My main question is, is it suitable to use an xml document for use as a template in php? or should I just stick to xhtml instead?
I really can't see the benefits of xml, but I'm hoping someone can show me. Why xml and not xhtml with a serverside language supporting it?
