How do I iterate over the child level elements only (ignoring the 
ones like <type>VkStructureType</type>)?
Do i have to check their parentage each time or is there an 
easier way?

Element.childNodes gives only direct children.

You could also do

document.querySelectorAll("types > type")

to get only the <type> tags that are a direct child of <types>.

(If you've ever done CSS or Javascript, this is similar syntax. I 
didn't implement the whole selector syntax and haven't kept up 
with any of the bleeding edge stuff, but all the basics work the 
same way.)
