<p>Libxml is made of multiple components; some of them are optional, and most
of the block interfaces are public. The main components are:</p>
<ul>
<li>an Input/Output layer</li>
  <li>FTP and HTTP client layers (optional)</li>
  <li>an Internationalization layer managing the encodings support</li>
  <li>a URI module</li>
  <li>the XML parser and its basic SAX interface</li>
  <li>an HTML parser using the same SAX interface (optional)</li>
  <li>a SAX tree module to build an in-memory DOM representation</li>
  <li>a tree module to manipulate the DOM representation</li>
  <li>a validation module using the DOM representation (optional)</li>
  <li>an XPath module for global lookup in a DOM representation
  (optional)</li>
  <li>a debug module (optional)</li>
</ul>
<p>Graphically this gives the following:</p>
