information about its encoding. Then the rest of the document is a text
format whose structure is specified by tags between brackets. <strong>Each
tag opened has to be closed</strong>. XML is pedantic about this. However, if
a tag is empty (no content), a single tag can serve as both the opening and
closing tag if it ends with <code>/&gt;</code> rather than with
<code>&gt;</code>. Note that, for example, the image tag has no content (just
an attribute) and is closed by ending the tag with <code>/&gt;</code>.</p>

long term structured document maintenance (where it follows the steps of

(glade), spreadsheets (gnumeric), or even shorter lived documents such as

used at startup to initialize the catalog, if the catalog should be
initialized with specific values xmlLoadCatalog() or xmlLoadCatalogs()
should be called before xmlInitializeCatalog() which would otherwise do a
default initialization first.</p>

preferences between public and system delegation,
xmlCatalogSetDefaultPrefer() allows this, xmlCatalogSetDefaults() and
xmlCatalogGetDefaults() allow to control if XML Catalogs resolution should
be forbidden, allowed for global catalog, for document catalog or both, the
default is to allow both.</p>

An entity defines an
abbreviation for a given string that you can reuse many times throughout the
content of your document. Entities are especially useful when a given string

document to a restricted area in the internal subset of the document (at the

finding them in the input).</p>

non-predefined entities in your documents, then the learning curve to handle

strongly suggest you consider using the DOM interface instead and let libxml
deal with the complexity rather than trying to do it yourself.</p>

<p>Libxml is the XML C library developed for the Gnome project. XML itself
is a metalanguage to design markup languages, i.e. text language where
semantic and structure are added to the content using extra &quot;markup&quot;
information enclosed between angle brackets. HTML is the most well-known
markup language. Though the library is written in C <a href="python.html">a
variety of language bindings</a> make it available in other environments.</p>

the content for a family of XML files. This is part of the XML 1.0
specification, and allows one to describe and verify that a given document
instance conforms to the set of rules detailing its structure and content.</p>

generally against a set of construction rules).</p><p>The validation process and building DTDs are the two most difficult parts
of the XML life cycle. Briefly a DTD defines all the possible elements to be
found within your document, what is the formal shape of your document tree
(by defining the allowed content of an element; either text, a regular
expression for the allowed list of children, or mixed content i.e. both text
and children). The DTD also defines the valid attributes for all elements and
the types of those attributes.</p>

something permanent or something which can evolve over time can be radically
different. Really complex DTDs like DocBook ones are flexible but quite
harder to design. I will just focus on DTDs for a formats with a fixed simple
structure. It is just a set of basic rules, and definitely not exhaustive nor

<code>--valid</code> option turns-on validation of the files given as input.
For example the following validates a copy of the first revision of the XML
1.0 specification:</p>
<p><code>xmllint --valid --noout test/valid/REC-xml-19980210.xml</code></p>
<p>the -- noout is used to disable output of the resulting tree.</p>
<p>The <code>--dtdvalid dtd</code> allows validation of the document(s)
against a given DTD.</p>
<p>Libxml exports an API to handle DTDs and validation, check the <a href="http://xmlsoft.org/html/libxml-valid.html">associated
description</a>.</p>
<h3><a name="Other1">Other resources</a></h3>
<p>DTDs are as old as SGML. So there may be a number of examples on-line, I
will just list one for now, others pointers welcome:</p>
<ul>
<li><a href="http://www.xml101.com:8081/dtd/">XML-101 DTD</a></li>
</ul>
<p>I suggest looking at the examples found under test/valid/dtd and any of
