Convertir XML a PDF en C# y VB.NET

Translated

View the article in English

Convertir XML de C# directamente a PDF puede ser un reto complejo. Hemos comprobado que al convertir XML a PDF en C#, lo mejor es empezar con XSLT como plantilla de transformación. A continuación, el XML puede convertirse en PDF mediante HTML(5) utilizando transformaciones XSLT. Los documentos XSLT definen cómo puede convertirse el XML de un esquema determinado en una representación HTML precisa y son un estándar bien establecido. En resumen, XSLT actúa como un traductor personalizado de XML a HTML.

Navegue hasta 'Uso de la clase XslCompiledTransformde Microsoft para obtener más información sobre la transformación XSLT.

Cómo convertir XML a PDF en C#

Instalar la biblioteca C# de XML to PDF Converter
Utiliza el Carga para importar la plantilla del transformador XSLT
Convertir XML a HTML en C# utilizando la función Transformar método
Renderizar el HTML a PDF con opciones de renderizado personalizadas
Exporte el documento PDF a la ubicación deseada

La cadena o archivo HTML resultante puede convertirse en un PDF utilizando la funciónGenerador de PDF .NET. Puede descargar un proyecto de ejemplo que muestra las capacidades de IronPDF para convertir XML a PDF desde aquíEjemplo de conversión de XML a PDF.
