The value
returned is an <strong>xmlDocPtr</strong> (i.e., a pointer to an
<strong>xmlDoc</strong> structure). This structure contains information such
as the file name, the document type, and a <strong>children</strong> pointer
which is the root of the document (or more exactly the first child under the
root which is the document). The tree is made of <strong>xmlNode</strong>s,
chained in double-linked lists of siblings and with a children&lt;-&gt;parent
relationship. An xmlNode can also carry properties (a chain of xmlAttr
structures). An attribute may have a value which is a list of TEXT or
ENTITY_REF nodes.</p><p>Here is an example (erroneous with respect to the XML spec since there
should be only one ELEMENT under the root):</p><p><img src="structure.gif" alt=" structure.gif " /></p><p>In the source package there is a small program (not installed by default)
called <strong>xmllint</strong> which parses XML files given as argument and
prints them back as parsed. This is useful for detecting errors both in XML
code and in the XML parser itself. It has an option <strong>--debug</strong>
which prints the actual in-memory structure of the document; here is the
result with the <a href="#example">example</a> given before:</p><pre>DOCUMENT
