Answer 1

를 사용하여 MON-FRI에 다음과 같은 변환합니까이 :

여기

File file = new File("YourXMLFile.xml"); 
    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); 
    DocumentBuilder db = dbf.newDocumentBuilder(); 
    Document doc = db.parse(file); 
    doc.getDocumentElement().normalize(); 
    NodeList nodeLst = doc.getElementsByTagName("days"); 

    if (nodeLst.getLenth() > 1) { 
    String first = ((Node) nodeLst.item(s)).getNodeValue().toString().toUpperCase(); 
    String last = ((Node) nodeLst.item(nodeLst.getLength() - 1)).getNodeValue().toString().toUpperCase(); 
    System.out.println(first + "-" + last); 
    } 

Answer 2

당신이 XStream을 라이브러리를 사용하는 예제를 이동 :

package MonFri.monfri; 

import java.util.List; 
import com.thoughtworks.xstream.XStream; 
import com.thoughtworks.xstream.io.xml.DomDriver; 


public class App 
{ 
@SuppressWarnings("unchecked") 
public static void main(String[] args) 
{ 

    XStream xstream = new XStream(new DomDriver()); 
    xstream.alias("day", String.class); 
    xstream.alias("Days", List.class); 
    List<String> days = (List<String>)xstream.fromXML(data); 
    String firstDay = days.get(0); 
    String lastDay = days.get(days.size()-1); 
    System.out.println(firstDay.toUpperCase() + "-" + lastDay.toUpperCase()); 
} 
private static String data = "<Days>\n" + 
     " <day>Mon</day>\n" + 
     "  <day>Tue</day>\n" + 
     "  <day>Wed</day>\n" + 
     "  <day>Thu</day>\n" + 
     "  <day>Fri</day>\n" + 
     "</Days>"; 
}
