Sitemap Validator

Valid sitemap with 2 URL(s) and 0 finding(s).

How it works

• Removed a byte-order mark and located the root element.
• Parsed each <url> (or <sitemap>) block and read its <loc> and optional elements.
• Validated absolute URLs, duplicates, ISO dates, changefreq and priority.

• A sitemap holds at most 50,000 URLs and 50 MB uncompressed.

Methodology

1. Strip a byte-order mark, then detect a <urlset> or <sitemapindex> root.
2. Extract each entry's elements (including CDATA) and unescape XML entities.
3. Validate structure, URL absoluteness, duplicate locs, ISO dates, changefreq and priority, and the protocol limits.

Usage

1. Paste the full sitemap XML.
2. Run the validator.
3. Read the URL count and each named finding.
4. Fix errors first, then warnings.

Examples

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

A valid two-URL sitemap

{
  "xml": "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<urlset xmlns=\"http://www.sitemaps.org/schemas/sitemap/0.9\">\n  <url><loc>https://gampangin.example/</loc></url>\n  <url><loc>https://gampangin.example/tools/</loc><lastmod>2026-10-01</lastmod></url>\n</urlset>"
}

A sitemap with a relative URL

{
  "xml": "<urlset xmlns=\"http://www.sitemaps.org/schemas/sitemap/0.9\"><url><loc>/relative</loc></url></urlset>"
}

Limitations

What the protocol requires

A sitemap is an XML document with a <urlset> root; each <url> must contain one <loc>. Optional <lastmod>, <changefreq> and <priority> refine the record.

A sitemap may hold at most 50,000 URLs and must be under 50 MB uncompressed; larger sites use a sitemap index.
