Can one get the "original" name of an element?

[marcoscaceres]

given:

const x = document.createElement("div");
x.innerHTML = "<TeSt>"
console.log(x.innerHTML); 
// "<test></test>"

For, x.firstElementChild, is it possible to get the, um, "original" name (i.e., "TeSt") that was used to create the element?

Checking the spec, I'm guessing no - but wanted to double check in case I missed it.

My understanding is that the parser is responsible for the lowercasing; the mixed-case name is never even passed to DOM's element-creation algorithms, so even if DOM wanted to store it somewhere, it couldn't.

On the other hand, if you are in an XML document, then the parser won't lowercase, I believe. So in that case it'll just be available as .localName.

@domenic, thanks for the clarification.
