Free extensions for Joomla!

I am trying to use xmap to generate a google news sitemap but are not seeming to have any luck.
I am using Joomla 2.5 with K2 and have entered my Publication name into the settings but when I select
the link for News Sitemap I receive a page with the title:
This XML file does not appear to have any style information associated with it. The document tree is shown below.
followed by:

Code: Select all

<urlset xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:news="http://www.google.com/schemas/sitemap-news/0.9" xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd"></urlset>

Not sure if I am doing something wrong here, any ideas please?
