How to set a redirect rule for multilingualism?

Question

Nginx

The site is multilingual, but because of this, there were problems with opening the site map (there are several of them). The map is successfully opened by url, mysite.my/RU_ru_sitemap_16-11-2020.xmlbut if the current language is present in the url - 404, for example mysite.my/ru/RU_ru_sitemap_16-11-2020
I try this, but it does not work

location ~ ^.*\.xml$ {
    if ($request_uri ~* "([^\/]{3,})\.xml?" ) {
        set  $last_path_component  $1;
        return 301 /$last_path_component;
    }
}

Tell me, how can I solve this problem?

Answer 1

rewrite "^/[a-z]{2}/(\w+_sitemap_[\d-]+)" /$1.xml permanent;

Or

location ~ "^/[a-z]{2}/(\w+_sitemap_[\d-]+)" {
    return 301 /$1.xml;
}
