Good I am trying to show the content of an XML through the JDOM library, but apparently it is not showing me the sub-nodes of a certain field of the XML file, I do not know if the solution I am trying to implement is quite new in this parceo of XML documents, I leave the code.

SAXBuilder builder = new SAXBuilder();
File xmlFile = new File( "E:\Desarollo\AED\workspace\Ficheros\libros.xml" );   
try
 {
       Document document = (Document) builder.build( xmlFile );
       Element rootNode = document.getRootElement();
        List list = rootNode.getChildren( "Libro" );


        for ( int i = 0; i < list.size(); i++ ) {

            Element Libros = (Element) list.get(i);

            String isbn = Libros.getAttributeValue("ISBN");
            String titulo = Libros.getAttributeValue("Titulo");
            System.out.println( "Titulo: " + titulo+" "+"ISBN= "+isbn );

            List<Element> lista_campos = Libros.getChildren();

            for ( int j = 0; j < lista_campos.size(); j++ ) {

                Element campo = (Element)lista_campos.get( j );

                String Ejemplar = campo.getChildTextTrim("Ejemplar");
                System.out.println(Ejemplar);

                String Autor = campo.getChildTextTrim("Autor");
                System.out.println(Autor);


            }
        }

And this is giving me the following console output

As you can see there are certain nodes that I put them to NULL my doubt is as follows as I get to print all the nodes not only the first, I leave you also the original XML file.

Any kind of help or advice to modify the code will be welcome thanks in advance community.

You're eating the Exemplary label so it does not work correctly because of that:

Element ejemplares = Libros.getChild("Ejemplares");
List<Element> listaEjemplares = ejemplares.getChildren();

for ( int j = 0; j < listaEjemplares.size(); j++ ) {
     Element campo = (Element)listaEjemplares.get( j );
     String Ejemplar = campo.getChildTextTrim("Ejemplar");
     System.out.println(Ejemplar);
}
Element autores = Libros.getChild("Autores");
List<Element> listaAutores = autores.getChildren();

for ( int j = 0; j < listaAutores.size(); j++ ) {
     Element campo = (Element)listaAutores.get( j );
     String Autor = campo.getChildTextTrim("Autor");
     System.out.println(Autor);
}
