Thread:Project:Support desk/How to separate sitemap into series small file?

I am using Manual:GenerateSitemap.php to generate sitemap now.

The world largest Chinese search engine Baidu notified me that they can't handle any sitemap larger than 50000 records. How can I separate sitemap every 50000 records? By default Generatesitemap.php separate siemap by namespace. However, even single "sitemap-zhmoegirlwiki-NS_0-0.xml.gz" contain more than 50000 links.
