XML Sitemap Generator — illustrative example

INPUT
Create sitemap XML for two canonical pages: https://example.com/tools/a/ and https://example.com/tools/b/. No last-modified dates are supplied.

RESULT
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
  <url><loc>https://example.com/tools/a/</loc></url>
  <url><loc>https://example.com/tools/b/</loc></url>
</urlset>

REVIEW
Include canonical URLs you want discovered, with correct XML escaping. A sitemap helps discovery but does not guarantee indexing or ranking.

This is a teaching example, not a live execution record.
