  <title>Exemple de fichiers collection.xml et collection.xsl</title>
  <para>
   De nombreux exemples de ce chapitre nécessitent à la fois un fichier XML et un fichier XSL.
   Nous utiliserons <filename>collection.xml</filename> et
   <filename>collection.xsl</filename> qui contiennent respectivement :

  <title>Gestion des erreurs avec les fonctions de gestion d'erreur libxml</title>
  <para>
   libxml fournit des fonctions pour gérer les erreurs qui peuvent être 
   utilisées pour capturer et gérér celles ci lors du traitement XSLT.
