I'm new to Jsitemap, but it looked like to only sitemap tool to do what I need.
I have one Joomla installation powering 3 websites (menus linked to template) in a lot of languages, all defined by domain. So both the menu+template and language are defined by the domain name. So there is no language dropdown and I'm not using the standard Joomla multi language but I'm using Falang instead.
trikke.nl needs a Dutch sitemap for menu 1
hpv.trikke.nl needs a Dutch sitemap for menu 2
skki.trikke.nl needs a Dutch site map for menu 3
trikke.pl needs a Polish sitemap for menu 1
hpv.poland.pl needs a Polish sitemap for menu2
And so on for +/- 20-30 domain/languages.
I hope someone can point me in the right direction on how to do. I've found http://storejextensions.org/faq/can-i-have-multiple-sitemaps-for-the-same-site.html
in the faq, but it is not helpful in my case.
