How to cancel a redirect to a page without a slash?

Question

Programming

Hello LiteSpeed
​​Shared Hosting .htaccess htaccess is set to redirect all URLs to a URL with a trailing slash:

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !(.*)/$
RewriteRule ^(.*[^/])$ $1/ [L,R=301]

What rule and where to add so that the desired page does not redirect to a URL with a slash?
There is a page sitemap.xmland it redirects to sitemap.xml/
PS For a
long time and often there are difficulties with understanding the rules of the htaccess file. What language are these rules written in? Are there any solid works on this subject? How many times I tried to find information, the same number of times I came across only someone's notes.

Answer 1

Add RewriteCond %{REQUEST_URI} !(\.xml)$
