title: Parse HTML using ruby core libraries? (ie, no gems required)
body: <p>Some friends and I have been working on a set of scripts that make it easier to do work on the machines at uni. One of these tools currently uses Nokogiri, but in order for these tools to run on all machines with as little setup as possible we've been trying to find a 'native' html parser, instead of requiring users to install RVM and custom gems (due to disk space limitations for most users).</p>
  
  <p>Are we pretty much restricted to Nokogiri/Hpricot/? Should we look at just writing our own custom parser that fits our needs?</p>
  
  <p>Cheers.</p>
  
  <p>EDIT: If there's posts on here that I've missed in my searches, let me know! S.O. is sometimes just too large to find things effectively...</p>
