Get element by xpath on HTML string

I have a JS variable that contains an a string that represents an HTML page. For example:

var response = "<!DOCTYPE html><html><body><h1>This is heading 1</h1></body></html>"

I’d like to perform query selectors and xpath evaluations on this response to traverse through the HTML elements. Since the response is not in the DOM I can’t use document.x actions.

One option is to write it into an invisible iframe in the DOM but this is not allowed for Chrome extensions. Are there any other alternatives?
