I basically want to add such urls to my existing sitemap index. I'm currently using WP SEO by yoast, but I'm open to trying out alternative plugins. My urls are currently like this...
e.g www.mysite.com/used-cars/location/paris/model/bmw-m3 & www.mysite.com/used-cars/model/bmw-m3
I want to have all these kind of urls in a loop, then push them into a sitemap.
How can I do this?
