Comparaison à d'autres formats

Pour savoir à quoi ressemble du XML, le mieux est certainement d'en voir. Commençons par un exemple simplifié. Il propose une transposition du début de cet article dans un langage XML appliqué à la documentation technique, DocBook.

                        xmlns="http://docbook.org/ns/docbook">            >Extensible Markup Language>                >                                                     >XML> (Extensible Markup Language,             « langage de balisage extensible »)...          >        >

Dans ce code, chacun peut identifier des portions de texte (exemple : Extensible, XML…) et des mots clés encadrés de chevrons (<, >) :

, , <para>… Ce <span class='lienGlossaire'><a href='https://www.techno-science.net/definition/221.html'>document</a></span> est ouvert par le mot clé <article>, et clos par </article>. Notez la <span class='lienGlossaire'><a href='https://www.techno-science.net/definition/10865.html'>barre oblique</a></span>, elle signifie la <span class='lienGlossaire'><a href='https://www.techno-science.net/definition/5308.html'>fermeture</a></span> de la balise article. En XML, une balise doit toujours être <i>fermée</i>. À l'intérieur de cet <i>article</i>, il y a un titre (<<span class="lang-en" lang="en" xml:lang="en"><i>title</i></span>>), un paragraphe (<para>), et un acronyme (<<span class="lang-en" lang="en" xml:lang="en"><i>acronym</i></span>>).</p> <p>Ce qui est spécifique à XML, c'est le choix des chevrons pour identifier les balises, et l'obligation de les fermer. Les mots clés ne sont pas définis par la <span class='lienGlossaire'><a href='https://www.techno-science.net/glossaire-definition/Norme.html'>norme</a></span> XML, mais par le vocabulaire choisi. En XHTML, l'élément racine aurait été <html>, en XSLT, cela peut être <xsl:stylesheet> ou <xsl:transform>. Ceci illustre la nature extensible d'XML. Ce n'est pas un jeu de noms réservés (exemple : <span class="lang-en" lang="en" xml:lang="en">echo, for, public, function, <span class='lienGlossaire'><a href='https://www.techno-science.net/glossaire-definition/CLASS.html'>class</a></span></span>…), mais plutôt des caractères réservés permettant de définir un « langage ».</p> <div lazyload="view"><!--lazy <div class="conteneurEncadre alignleft"> <div class="encadre encadreleft encadrePub"> <ins class="adsbygoogle" style="display:inline-block;width:300px;height:250px" data-ad-client="ca-pub-6990544335324031" data-ad-slot="7286811235"></ins> <script> (adsbygoogle = window.adsbygoogle || []).push({}); </script> </div> </div> lazy--></div> <p>Cet exemple illustre une autre spécificité de ce format. À part SGML, peu d'autres syntaxes permettent de séparer la <span class='lienGlossaire'><a href='https://www.techno-science.net/definition/6402.html'>définition</a></span> sémantique de l'information (qu'est-ce qui est titre, lien, section…), de l'apparence qu'on lui souhaite (aujourd'hui un titre est souligné, demain on le voudra peut-être en bleu). Cela fait d'XML un excellent format pour conserver des textes ou des <span class='lienGlossaire'><a href='https://www.techno-science.net/definition/222.html'>données</a></span>. Pour s'en convaincre, regardons ce que la même information donne dans d'autres formats.</p> <h3> <span class="mw-headline" id="Formats_binaires_.28un_exemple_Microsoft_Word.29">Formats binaires (un exemple <span class='lienGlossaire'><a href='https://www.techno-science.net/definition/416.html'>Microsoft</a></span> Word)</span></h3> <p>Les logiciels, surtout pour le grand public, aboutissent généralement à des fichiers. Le format se soucie d'abord d'être fiable et performant, mais est-il échangeable ? Le format d'enregistrement natif du traitement de texte Word est l'exemple du <span class="need_ref" style="cursor:help;" title="Ce passage nécessite une référence.">format binaire le plus déployé</span>. Il n'est pas lisible par l'humain. Le texte est difficile à extraire, le lien avec sa structuration (gras, italique…) est difficile à reconstruire. Dans la pratique, un document Word pose beaucoup de problèmes de conservation sur le long terme.</p> <pre> ÐÏ à¡± á > þÿ ! # þÿÿÿ ÿÿ% ð ¿ a bjbj%ç%ç Extensible Markup Language XML (Extensible Markup Language, « langage de balisage extensible ») i 8 @ñÿ 8 N o r m a l CJ _H aJ mH sH tH N @ N T i t r e 1 ÿ <b>[… beaucoup d'informations binaires supprimées ]</b> ÿ ÿÿÿÿ À F Document <span class='lienGlossaire'><a href='https://www.techno-science.net/glossaire-definition/Microsoft-Word.html'>Microsoft Word</a></span> MSWordDoc Word.Document.8 ô9²q </pre> <p>L'éditeur, Microsoft, propose désormais un format d'enregistrement en XML.</p> <h3> <span class="mw-headline" id="RTF_.28Rich_Text_Format.29">RTF (Rich Text Format)</span></h3> <p>Afin de favoriser l'échange avec d'autres traitements de texte, Microsoft proposa RTF <span class="lang-en" lang="en" xml:lang="en"><i>Rich Text Format</i></span> « format texte riche » (1987).

Ainsi, {\b XML} indique que les lettres XML sont en gras, <i>bold</i> : \b. Pour le titre, humains comme logiciels ne peuvent pas l'identifier par "\f2\fs36\b", ce code indique en fait l'apparence du paragraphe (gras, gros…).
