title: Best XML DB for a PHP website?
body: <p>I'm planning on writing a RSS Feed Aggregator with a team, but I'm wondering what XML Database we should use. The server currently runs IIS 6.0 with PHP 5.3.0 x64, I understand already that I need both a server application and a PHP extension. </p>
  
  <p>What I've discovered already:</p>
  
  <ul>
  <li>Galax
  
  <ul>
  <li>Have previously used this at university, but I <strong>can't find information</strong> about it on google, it tends to show information about something else named Galax or the Galaxy...</li>
  </ul></li>
  <li><a href="http://exist.sourceforge.net/" rel="nofollow noreferrer">eXist</a>
  
  <ul>
  <li>Together with <a href="http://query-exist.sourceforge.net/" rel="nofollow noreferrer">Phexist</a> this seems like a last resort, although it's dated from 2007.</li>
  <li>Bad documentation.</li>
  <li>Wondering if it has all features I will need through the development.</li>
  </ul></li>
  <li><a href="http://modis.ispras.ru/sedna/" rel="nofollow noreferrer">Sedna</a>
  
  <ul>
  <li>Looks professional and does have API support for PHP.</li>
  <li>Good documentation!</li>
  <li>Wondering if it has any disadvantages.</li>
  </ul></li>
  <li><a href="http://www.oracle.com/database/berkeley-db/xml/index.html" rel="nofollow noreferrer">Berkeley DB XML</a>
  
  <ul>
  <li>Also looks professional, Oracle is well-known and I have heard of Berkeley before...</li>
  <li>Can't find documentation right away, only an old presentation.</li>
  <li>I will have to mess around with trying to get the PHP extension to compile.</li>
  </ul></li>
  <li><a href="http://sourceforge.net/projects/saxon/" rel="nofollow noreferrer">Saxon</a>
  
  <ul>
  <li>Hard to <a href="http://sourceforge.net/apps/mediawiki/saxon/index.php?title=Saxon-from-PHP" rel="nofollow noreferrer">set-up in PHP</a> and seems bloated and unstable when you do so.</li>
  </ul></li>
  <li>...
  
  <ul>
  <li>Are there any other solutions?</li>
  <li>Is PHP good enough for this?</li>
  </ul></li>
  </ul>
  
  <p>I would love to hear your opinions on the best way to accomplish this, thanks in advance!</p>
