I recently did some changes to my sitemap because i updated my website to support two languages but now i get an error when submitting the sitemap and i don't see where the problem is.
Your Sitemap or Sitemap index file does not properly declare the namespace.
> Examples
> Line 5
> Parent tag:
> url
> Tag:
> link
<urlset xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:xhtml="http://www.w3.org/TR/xhtml11/xhtml11_schema.html" xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd http://www.w3.org/TR/xhtml11/xhtml11_schema.html http://www.w3.org/2002/08/xhtml/xhtml1-strict.xsd">

***Update
Tried this method like the Google Documentation says so
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"
xmlns:xhtml="http://www.w3.org/1999/xhtml">
Although when using xmlns:xhtml="http://www.w3.org/1999/xhtml" converts the xml to plain text, changing http to https outputs the xml correctly and does the work but i have read you must use only http to avoid my issue, honestly this it too confusing.
