węzeł dziecko idą jak ten USER_ID = „testpub2” muszę konwertować xnode i uzyskać wartość jak ukryty węzeł xml? i weź wartość za pomocą saxparser. czy mogę wziąć wartość bezpośrednio?

Answer 1

Poniższy kod przekształca ciąg na dokument XML. Gdy już masz dokument, możesz nawigować w węzłach lub możesz pisać do pliku itp.

import java.io.*; 
import javax.xml.parsers.*; 
import org.w3c.dom.*; 
import org.xml.sax.*; 

public class Util { 

    public static Document stringToDom(String xmlSource) 
      throws SAXException, ParserConfigurationException, IOException { 
     DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); 
     DocumentBuilder builder = factory.newDocumentBuilder(); 
     return builder.parse(new InputSource(new StringReader(xmlSource))); 
    } 
} 

Answer 2

public void writeFile(String yourXML){ 
    BufferedWriter out = new BufferedWriter(new FileWriter("outfilename.xml")); 
    try { 
     out.write(yourXML); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } finally { 
     out.close(); 
    } 
}
