How to filter items out of sitemap using custom code

I just recently was able to do this by creating a custom URL Generator based on the EntityUrlGenerator plugin.

There you can alter the entity query used to identify which entities you wish to have included in the final result set. I used it to key off of a custom boolean on my site. That way I could intentionally exclude content based on whatever I wanted.

And since it's using an entity query, you can query based on anything the entity query system and access.

Either create a new URL generator by code and use it within the UI or just use the sitemap links alter hook (see Readme) to filter out entities beyond a certain creation date.

When it comes to having certain content types indexed in certain sitemap, this is already possible without custom code.

Let me know if yiu need further pointers.
