Convertir XML en PDF en C# et VB.NET

Translated

View the article in English

La conversion de XML C# directement en PDF peut s'avérer complexe. Nous avons constaté que lors de la conversion de XML en PDF en C#, il est préférable de commencer par utiliser XSLT comme modèle de transformation. XML peut ensuite être converti en PDF via HTML(5) en utilisant des transformations XSLT. Les documents XSLT définissent comment le langage XML d'un schéma donné peut être converti en une représentation HTML précise et constituent une norme bien établie. En bref, XSLT agit comme un traducteur personnalisé de XML à HTML.

Comment convertir XML en PDF en C#

Installer la bibliothèque C# de XML to PDF Converter
Utiliser le Chargement pour importer un modèle de transformateur XSLT
Convertir XML en HTML en C# à l'aide de la fonction Transformer méthode
Rendre le HTML en PDF avec des options de rendu personnalisées
Exporter le document PDF à l'emplacement souhaité

La chaîne ou le fichier HTML qui en résulte peut ensuite être rendu sous forme de PDF à l'aide de la fonction.NET Générateur de PDF. Vous pouvez télécharger un exemple de projet présentant les capacités d'IronPDF à convertir du XML en PDF à partir de ce lienExemple de conversion de XML en PDF.
