Inserting arbitrary HTML into a DocumentFragment

Question

I know that adding innerHTML to document fragments has been recently discussed, and will hopefully see inclusion in the DOM Standard. But, what is the workaround you\'re sup

Answer 1

No one ever provided the requested "easy one-liner".

Given the variables…

var html = '
x
y';
var frag = document.createDocumentFragment();

… the following line will do the trick (in Firefox 67.0.4):

frag.append(...new DOMParser().parseFromString(html, "text/html").body.childNodes);
