The
11valuereturned is an <strong>xmlDocPtr</strong>(i.e., a pointer to
12an<strong>xmlDoc</strong>structure). This structure contains information
13suchas the file name, the document type, and a
14<strong>children</strong>pointerwhich is the root of the document (or more
15exactly the first child under theroot which is the document). The tree is
16made of <strong>xmlNode</strong>s,chained in double-linked lists of siblings
17and with a children&lt;-&gt;parentrelationship. An xmlNode can also carry
18properties (a chain of xmlAttrstructures). An attribute may have a value
19which is a list of TEXT orENTITY_REF nodes.</p><p>Here is an example (erroneous with respect to the XML spec since
20thereshould 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
21default)called <strong>xmllint</strong>which parses XML files given as
22argument andprints them back as parsed. This is useful for detecting errors
23both in XMLcode and in the XML parser itself. It has an option
24<strong>--debug</strong>which prints the actual in-memory structure of the
25document; here is theresult with the <a href="#example">example</a>given
