Create dynamic sitemap on ruby on rails

Sitemaps are an easy way for webmasters to inform search engines about pages on their sites that are available for crawling. In its simplest form, a Sitemap is an XML file that lists URLs for a site along with additional metadata about each URL (when it was last updated, how often it usually changes, and how important it is, relative to other URLs in the site) so that search engines can more intelligently crawl the site. It’s basically a XML file describing all URLs in your page: The following example shows a Sitemap that contains just one URL and uses all optional tags. The optional tags are in italics. <?xml version="1.0" encoding="UTF-8"?> <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">    <url>       <loc>http://www.example.com/</loc>       <lastmod>2005-01-01</lastmod>       <changefreq>monthly</changefreq>     ...
