Index file map

[boyer.brice.1981]

Hello, I am scanning a directory containing sitemaps by Unlimited PHP Sitemap Generator unfortunately this one does not create the necessary index for me:
</ Sitemap>
https: //www.sitemap1.xml
https: //www.sitemap2.xml
<Sitemap>

But use the usual syntax:
<Url>
<Loc>
https: //www.sitemap1.xml
https: //www.sitemap2.xml
</ Loc>
</ Url>

How to do ?
