How to generate sitemap for root domain from sub-domain?

[kat.joker]

Hi,
I installed the sitemap generation script on my sub-domain (sub.mydomain.com) , is there anyway for the script to generate sitemap for the root domain (sitemap.xml for [ External links are visible to forum administrators only ]) ?

Hello,

you can specify your main domain as Starting URL.
