The Sitemap Generator described in that Documentation article is a feature that was added in Sitefinity 7.1, you will not find it in earlier versions.
If you do not want to upgrade your project to Sitefinity 7.1 you could use the sample provided in GitHub
. You can take a look at this blog post
, which explains how this module works in details. You can install the module in your project and generate the sitemap for the project.
However I recommend you to upgrade your project to Sitefinity 7.1 so you may use this feature out-of-the-box.
