javascript - How to execute document.querySelectorAll on a text string without inserting it into DOM

var html = '<p>sup</p>'

I want to run document.querySelectorAll('p') on that text without inserting it into the dom.

In jQuery you can do $(html).find('p')

If it's not possible, what's the cleanest way to to do a temporary insert making sure it doesn't interfere with anything. then only query that element. then remove it.

(I'm doing ajax requests and trying to parse the returned html)

With IE 10 and above, you can use the DOM Parser object to parse DOM directly from HTML.

var parser = new DOMParser();
var doc = parser.parseFromString(html, "text/html");
var paragraphs = doc.querySelectorAll('p');
