Java Dom getAttribute

Question

即時嘗試解析XML文件，但它不會打印屬性值。我不知道如何從手機

try { String subor = "Noviny.xml"; 
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); 
DocumentBuilder builder = factory.newDocumentBuilder(); 
Document document = builder.parse(subor); 
System.out.println("----------------\n"); 
NodeList nodelist = document.getElementsByTagName("Author"); 
NodeList nodelist1 = document.getElementsByTagName("Article"); 
for(int i = 0; i < nodelist.getLength(); i++) { 
    Node uzol = nodelist.item(i); 
    if (uzol.getNodeType() == Node.ELEMENT_NODE) 
    { 
     Element element = (Element) uzol; 
     System.out.println("Id:" + element.getElementsByTagName("Id").item(0).getTextContent() + "\n"); 
     System.out.println("Name:" + element.getElementsByTagName("Name").item(0).getTextContent() + "\n"); 
     System.out.println("Email:" + element.getElementsByTagName("Email").item(0).getTextContent() + "\n"); 
     System.out.println("typ: " + element.getAttribute("typ") + "\n"); 
     System.out.println("phone:" + element.getElementsByTagName("phone").item(0).getTextContent() + "\n"); 
     System.out.println("typ: " + element.getAttribute("typ") + "\n"); 
     System.out.println("sal: " + element.getElementsByTagName("sal").item(0).getTextContent() + "\n"); 
    } 


    catch (Exception e) { 
    e.printStackTrace(); 
} 

和XML

<Noviny> 
    <Author> 
    <Id>1</Id> 
    <Name>first</Name> 
    <Email>first@gmail.com</Email> 
    <phone typ="mobil">09443916565</phone> 
    <sal>500</sal> 
    </Author> 
    <Author> 
    <Id>2</Id> 
    <Name>second</Name> 
    <Email>second@gmail.com</Email> 
    <phone typ="pevna">094415665465</phone> 
    <sal>1000</sal> 
    </Author> 

還有一件事屬性類型：NIS有可能只是打印XML文件（的System.out.println）樹表示？

謝謝

您目前正在尋求的<Author>元素的typ屬性（兩次，出於某種原因）。您應該獲取<phone>元素（您已經在做），然後要求屬性爲元素，而不是<Author>元素。
