The second one is created using XML - Extensible Makeup Language. This is the one most people pay more attention to. Google Webmaster Tools account uses it to analyze a submitted blog/website and generate reports such as Overview, Diagnostics, Statistics, Links, Sitemaps, and Tools for it. A sample format of a XML Sitemap with one single URL would look like this:
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
<loc>http://www.yoursite.com/</loc> <lastmod>2007-12-29</lastmod> <changefreq>monthly</changefreq> <priority>0.5</priority> </url> |
P.S. The bolded parts you need to plot in your correct information.
