Generated a sitemap with 2 URL(s) and 0 finding(s).

Split the URL list, trim blank lines and remove exact duplicates.
Validate each URL is absolute and within the protocol length limit.
Emit a UTF-8 XML declaration and a <urlset> with one <url> per entry, escaping XML metacharacters.

These are examples, not current values: they use fixed inputs, while the interactive tool computes live results in your browser.

A sitemap lists the URLs you want crawled. It is a hint, not a directive; a URL is only indexed if it is crawlable and useful.

Keep the URL set canonical: list the preferred URL, not every variant.

Does the sitemap need a lastmod?: No. lastmod is optional and, when present, should be the last significant modification date, not the build date.
Should I use priority?: Google says priority is ignored for ranking. It is still part of the protocol, so use it only if another consumer needs it.
