How to create a FULL RSS feed from a VK Community wall?

Question

RSS

There was a need to create a file with a FULL rss feed of the VKontakte Community wall. Now I can only pick up the last 10 entries (out of more than 500).
Such a feed is needed for further importing posts to a WordPress site.
We decided to make the site the main one, and from it already do cross-posting in VK.
Thank you!

Answer 1

we take api https://vk.com/dev/wall.get and write a simple script.

Answer 2

The rss format is not intended for parsing.
Use api vk.

Answer 3

Or use the service feed.exileed.com/vk/info
