iceq on "[Plugin: WordPress SEO by Yoast] xml sitemap displays links as text not links"

Can someone please tell me how is this xml supposed to be displayed?

What I have is this:
http://personal.al-rasid.com/sitemap_index.xml

And this
http://personal.al-rasid.com/post-sitemap.xml

As you see it's pure text not hyperlinks. Is this normal?

BTW, another plugin seems to be generating the sitemap just fine:
http://personal.al-rasid.com/sitemap.xml
