      creating and manipulating <span class="acronym">XML</span> data. This tutorial
    provides example code and explanations of its basic functionality.</p><p>Libxml and more details about its use are available on <a href="https://gitlab.gnome.org/GNOME/libxml2" target="_top">the project home page</a>. Included there is complete <a href="https://gnome.pages.gitlab.gnome.org/libxml2/devhelp/general.html" target="_top">
	<span class="acronym">API</span> documentation</a>. This tutorial is not meant
    to substitute for that complete documentation, but to illustrate the
    functions needed to use the library to perform basic operations.

</p><p>The tutorial is based on a simple <span class="acronym">XML</span> application I
    use for articles I write. The format includes metadata and the body
    of the article.</p><p>The example code in this tutorial demonstrates how to:
      </p><div class="itemizedlist"><ul type="disc"><li><p>Parse the document.</p></li><li><p>Extract the text within a specified element.</p></li><li><p>Add an element and its content.</p></li><li><p>Add an attribute.</p></li><li><p>Extract the value of an attribute.</p></li></ul></div><p>
