This is an example of XML fomate sitemap
A site map is a file in which you can provide information about web pages, videos, or other files in your website and explain the relationship between these contents. Search engines such as Google will read this file to more efficiently crawl your website. The site map will tell Google which pages and files in the website you think are important and provide important information about these files. For example, when the page was last updated and whether the page has any alternate language versions.
