get opening tag including attributes - outerHTML without innerHTML

Question

I would like to retrieve a certain tag element with its attributes from the DOM. For example, from

  link text
         


        

Answer 1

If someone is not using jQuery . . .

elem.outerHTML
"
  link text
"
elem.cloneNode().outerHTML
""

If you want to be safe for Firefox etc. released before mid-2014, use cloneNode(false) to avoid getting inner stuff.
