title: How do I remove some (or all) HTML elements and/or attributes using HTML Agility Pack?
body: <p>Using the <a href="http://htmlagilitypack.codeplex.com/" rel="nofollow noreferrer">HTML Agility Pack</a>, how can I remove all HTML attributes, elements, etc, etc, from a blob of HTML, with the result as if I pasted it into notepad?</p>
  
  <p>Additionally, I need to remove all formatting but I need to keep UL/LI and B tags.</p>
