코드입니다 :

다음은 내 XML 파일입니다 IT는 XML 축구의 첫 번째 값을 출력하고 다음을 인쇄 할 수 없습니다.

nodeLst = doc.getElementsByTagName("Sport"); 
for (int i = 0; i < nodeLst.getLength(); i++) { 

    Node myNode = nodeLst.item(i); 

    if (myNode.getNodeType() == Node.ELEMENT_NODE) { 

     Element Sport = (Element) myNode; 
     NodeList Name= Sport 
     .getElementsByTagName("Name"); 
     Element NameElement = (Element) Name.item(0); 
     NodeList Namevalue = NameElement.getChildNodes(); 
     System.out.println("Name : " 
    + ((Node) Namevalue.item(0)).getNodeValue()+"|"); 

    //This gives me null value 
     NodeList Category = Sport 
     .getElementsByTagName("Category"); 
     Element CategoryName= (Element) Category 
     .item(0); 
     NodeList Categoryvalue = CategoryName 
     .getChildNodes(); 
     System.out.println("Category: " 
     + ((Node) Categoryvalue.item(0)) 
     .getNodeValue()); 
    } 
} 

첫 번째 데이터 Soccer.The 두 ​​번째는 단지 null 값을 제공 할 수 있습니다. 로

내가 내 결과를 필요

:

Soccer | Australia | Hyundai A-League | Wellington Phoenix FC - Melbourne Victory : 2 - 0 
Soccer | England | Premier League | Blackpool FC - Birmingham City : 5 - 1
