如何使用DOM解析n級xml

Question

我需要解析n級xml文件並顯示其元素。它永遠不會有任何屬性。 我當前的代碼

String xmlInputFile="reportA.xml" ; 
     File file =new File(xmlInputFile); 
     Document document; 
     DocumentBuilder documentBuilder; 
     DocumentBuilderFactory documentBuilderFactory; 
     NodeList nodeList; 
     documentBuilderFactory = DocumentBuilderFactory.newInstance(); 
     documentBuilder = documentBuilderFactory.newDocumentBuilder(); 
     document = documentBuilder.parse(xmlInputFile); 

     document.getDocumentElement().normalize(); 
     nodeList = document.getElementsByTagName("*"); 
     for (int index = 0; index < nodeList.getLength(); index++) { 
      Node nodeA = nodeList.item(index); 
      if (nodeA.getNodeType() == Node.ELEMENT_NODE) { 
       Element element = (Element) nodeA; 
       if(element.hasChildNodes()){ 
        System.out.println("Name "+element.getNodeName()+" value "+element.getFirstChild().getNodeValue().trim()); 
       } 
      } 
     } 

我的XML文件是

<?xml version="1.0" encoding="UTF-8" ?> 
<company> 
    <record> 
     <name> 
      <firstName>Brad</firstName> 
      <lastName>Pitt</lastName> 
     </name> 
     <age>41</age> 
     <dob>31/8/1982</dob> 
     <income>200,000</income> 
    </record> 
</company> 

目前放出來的是：

Name company value 
Name record value 
Name name value 
Name firstName value Brad 
Name lastName value Pitt 
Name age value 41 
Name dob value 31/8/1982 
Name income value 200,000 

我不需要公司，唱片，名字。如何刪除這些元素？

改變了代碼到

nodeList = document.getElementsByTagName("*"); 
     for (int index = 0; index < nodeList.getLength(); index++) { 
      Node nodeA = nodeList.item(index); 
      if (nodeA.getNodeType() == Node.ELEMENT_NODE) { 
       NodeList nodeList1 = nodeA.getChildNodes(); 
       if(nodeList1.getLength()<=1){ 
        String value=""; 
        if(nodeList1.getLength()!=0){ 
         value= nodeA.getFirstChild().getNodeValue(); 
        } 
        System.out.println("Name "+nodeA.getNodeName()+" value "+ value); 
       } 
      } 

     } 

現在只有根節點越來越打印。不過，我想看看有沒有人有更好的想法..
