13267	Implement htmlParser.element.find() method	Piotrek Koszuliński		"It is hard to find matching elements in `htmlParser.element`. Real DOM has couple of methods like find, findOne, byId, byClass, etc., but HMTL parser has nothing except `forEach()` which allows you to iterate over the entire sub tree and find whatever you need.

Implementing find/findOne which would work in the same way as in real DOM is reasonable, because the CSS selectors implementation would be huge. Therefore, I propose a simpler method accepting a callback or element name. It can be implemented in few lines of code using `forEach()`.

Based on #12854."	Bug	confirmed	Normal		General
