Retrieve spell IDs of all the additional spells learned from a talent?
 

Is there a way to get all the spell IDs of spells that can be learned from a talent (without learning the talent)?

I mean those talents that give you access to multiple spells (druid affinities, warlock summoning circle, maybe others).

Guardian Affinity for example adds the following spells to the spellbook as balance druid:

Thick Hide
Thrash
Ironfur
Frenzied Regeneration

I can parse the spell description to get all the (localized) spell names, but didn't yet find a way to retrieve spell IDs. Maybe someone has an idea (if it's even possible)?
