Sitemap and XML sitemap

Question

I originally had a sitemap using the sitemap module. I've now installed and enable dthe xml sitemap module instead. After following the instructions and configuring xml sitemap, when I go to mysite/sitemap.xml all I see is an unstyled page with an ugly table listing the Links.

How would I go about styling this sitemap? I was expecting it to work like the Sitemap module does and generate a page using a default template, but I guess I was wrong, or am I?

How should a sitemap.xml display after it's been set up?
