To demonstrate using a Sitemap to investigate content, we will use the Gap website.

Gap has a well structured website with a Sitemap to help web crawlers locate their updated content. If we use the techniques from Chapter 1, Introduction to Web Scraping, to investigate a website, we would find their robots.txt file at http://www.gap.com/robots.txt, which contains a link to this Sitemap:

Sitemap: http://www.gap.com/products/sitemap_index.xml

Here are the contents of the linked Sitemap file:
