Contomatix Sitemap URL Extractor: Pull every URL out of a sitemap.xml into a list, free

Hi Product Hunt! Anyone who audits a site, plans a migration or builds a redirect map starts by getting the URLs out of a sitemap. The file is XML, so pulling the list out by hand is slow and easy to get wrong. Paste a sitemap.xml and the Sitemap URL Extractor gives you a clean list of every URL, with optional last-modified dates as CSV. It reads sitemap index files too, filters by path (for example only /blog/), removes duplicates and decodes XML entities. Everything runs in your browser: nothing is uploaded and there is no signup. It does not fetch a sitemap from a URL, because browsers block that for most sites, so you paste the contents. Compressed .xml.gz files need unzipping first. I would love feedback on what you would want next, for example grouping URLs by folder.
