I also have custom DOM helpers I carry around with me:

* getNodesByType - allows me to get things like attributes, text, and comments directly

* getAncestor - allows me to get a specified element somewhere between a target element and the document.documentElement

getAncestor is built-in: element.closest() :)

Slow. It uses a selector as an argument, which requires a parse step. It doesn’t take much effort to write something substantially better.
