<sentence> 
    <one> sentence one </one> 
    <two> sentence two</two> 
    <three> sentence three</three> 
    <four> sentence four </four> 
    <five> sentence five </five> 
    <six> sentence six </six> 
    <seven> sentence seven </seven> 
    <eight> sentence eight </eight> 
    <nine> sentence nine </nine> 
    <ten> sentence ten </ten>

請你就如何使用Java解析XML谷歌搜索！ – Keerthivasan

使用XStream，JAXB或使用DOM或SAX解析器解析它。 –

感謝您的回覆我得到了解決方案..... – Ankita

嘗試：

//package test; 

import java.io.IOException; 
import java.io.StringReader; 
import java.util.HashMap; 
import java.util.Map; 
import java.util.logging.Level; 
import java.util.logging.Logger; 
import javax.xml.parsers.DocumentBuilder; 
import javax.xml.parsers.DocumentBuilderFactory; 
import javax.xml.parsers.ParserConfigurationException; 
import org.w3c.dom.Document; 
import org.w3c.dom.Element; 
import org.w3c.dom.Node; 
import org.xml.sax.InputSource; 
import org.xml.sax.SAXException; 

public class Test { 

    private static final String xmlString = "<?xml version=\"1.0\" encoding=\"utf-8\"?>\n" 
      + "<sentence>\n" 
      + " <one> sentence one </one>\n" 
      + " <two> sentence two</two>\n" 
      + " <three> sentence three</three> \n" 
      + " <four> sentence four </four>\n" 
      + " <five> sentence five </five> \n" 
      + " <six> sentence six </six> \n" 
      + " <seven> sentence seven </seven>\n" 
      + " <eight> sentence eight </eight>\n" 
      + " <nine> sentence nine </nine> \n" 
      + " <ten> sentence ten </ten>\n" 
      + "</sentence>"; 

    public static void main(String[] args) throws IOException, SAXException { 

     try { 

      Map<String, String> hMap = new HashMap(); 
      DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance(); 
      DocumentBuilder dBuilder = dbFactory.newDocumentBuilder(); 
      InputSource is = new InputSource(new StringReader(xmlString)); 
      Document doc = dBuilder.parse(is); 

      Node node = doc.getElementsByTagName("sentence").item(0); 
      String keys[] = {"one", 
       "two", 
       "three", 
       "four", 
       "five", 
       "six", 
       "seven", 
       "eight", 
       "nine", 
       "ten"}; 

      for (String kValue : keys) { 
       if (node.getNodeType() == Node.ELEMENT_NODE) { 
        hMap.put(kValue, ((Element) node).getElementsByTagName(kValue).item(0).getTextContent()); 
       } 
      } 

      for (String key : keys) { 
       System.out.println(hMap.get(key)); 
      } 

     } catch (ParserConfigurationException ex) { 
      Logger.getLogger(Test.class.getName()).log(Level.SEVERE, null, ex); 
     } 

    } 
}

輸出：

sentence one 
sentence two 
sentence three 
sentence four 
    sentence five 
sentence six 
sentence seven 
sentence eight 
    sentence nine 
    sentence ten
