XML Advantages?

[opulyst]

I have heard that using XML for websites can have an advantage in SEO, could somebody please explain to me how XML would be advantageous for SEO?

None that I can think of. XML is mainly useful on the server-side, and therefore the client can't tell that you are using XML at all. Client-side XML only works within the context of a specific browser (see an example in this [webmasterworld.com] thread).

XML does have advantages for maintaining the web site. I use it on the server-side to maintain my site map. By using it, all my web pages are consistent: the title attribute that links to a page is exactly the same as the description meta tag of the page that it links to, for example, since they both come from the same attribute in the XML file. It gives a consistent look and feel across the entire web site.
