title: How Can I Parse a Document and Replace the Content to Change Context from 1st or 2nd Person to 3rd Person?
body: <p>Basically I need some text like:</p>
  
  <ul>
  <li>I have an ice cream cone.</li>
  <li>You are in trouble.</li>
  <li>You need a bath.</li>
  </ul>
  
  <p>And change it from 1st or 2nd person to 3rd person.</p>
  
  <ul>
  <li>He has an ice cream cone.</li>
  <li>He is in trouble.</li>
  <li>He needs a bath.</li>
  </ul>
  
  <p>I've started a js app, but it's super simple at the moment.</p>
  
  <p>Before I waste time reinventing the wheel, I figured I'd ask: Is anyone aware of any 3rd party libraries that do this sort of thing? If not, does anyone have any advice or guidance to offer to help me get something going?</p>
