Добавить новый тег в файл XML с различными атрибутами

Question

Я пытаюсь добавить новую строку тега "" с разными атрибутами. Я могу редактировать существующую строку, но не могу добавить новый тег, имеющий разные атрибуты.

XML-файл

Java Code

private static void updat() { 
    NodeList similarmodels = doc.getElementsByTagName("similarModels"); 
    Element model = null; 
    for(int i=0; i<similarmodels.getLength();i++){ 
     model = (Element) similarmodels.item(i); 
     String model = model.getElementsByTagName("similarModel").item(0).getFirstChild().getNodeValue(); 
     if(model.equalsIgnoreCase("KD440")){ 
      model.setAttribute("A"); 
     }else{ 
      model.setAttribute("B"); 
     } 
    } 
} 

Есть ли способ сделать это в JAXB & xsd ??

Answer 1

Не должно быть проблем ни с DOM, ни с JAXB. В JAXB вы должны просто создать новый объект SimilarModel, который затем можно добавить в список объектов SimilarModels.
