title: Is it possible to create a new dom using select parts from another dom? Or prune away unwanted parts
body: <p>I'm wondering if its possible to load a html page but only display a few select parts of it.</p>
  
  <p>Two possible approaches come to mind:</p>
  
  <p>1) Delete parts of the dom I'm not interested in.
  However I wouldn't know what all those parts are, I'd only know the parts I'm interested in.
  Is it possible to find the parts I'm interested in then remove everything else?</p>
  
  <p>2) Create a new dom which has been made by extracting parts of the dom from the original.
  Is it possible to somehow create this in parallel to the existing dom and make the browser switch to this new dom? Or alternatively create a html page from this new dom and then load that?</p>
  
  <p>Are these crazy ideas? Any simple / alternative solutions?</p>
