What this XML sitemap validator does
This XML sitemap validator checks whether the sitemap code you paste is well-formed XML that follows the sitemap structure, and it counts the URLs the file contains. Paste the XML and run it to get either a clean pass with the URL count, or the first error it finds in the file, which is usually the fastest route to the underlying problem.
When a quick check saves time
Sitemaps are often generated by plugins or scripts, and a small syntax slip can make the whole file unreadable to search engines. A paste-in check suits the moment before you submit a sitemap, after a site move, or when a generated file suddenly looks different from the one that worked last month.
Good to know
This is a simple validator: it checks XML syntax and sitemap structure only. It does not visit the listed addresses, so it cannot tell you whether they exist, redirect, or return errors; that check belongs to your server logs and search console.
Frequently asked questions
What does well-formed mean here?
It means the XML follows the rules of the format: tags open and close correctly, the document nests properly, and the sitemap elements sit where the protocol expects them. A single broken tag can make a whole file fail.
Does a valid sitemap mean my pages will be indexed?
No. Validity only means search engines can read the file and find the addresses. Whether those pages get indexed depends on the pages themselves, their content and their signals, which this check does not judge.
Why does it report only the first error?
XML parsers stop at the first place the document breaks, because everything after that point is unreliable. Fix the reported error and run the check again; a file with several slips may need a few passes.

Limitations
This is a simple validator: it checks XML syntax and sitemap structure, not whether listed URLs exist or return 200.
