Hi, i have a question about parsing file in Java.
How would i parse a specific line in file such as XML or txt file and is static so i can use it anywhere in the applet? Below is example of text i want to parse.

For XML file <configuration> <main> <theme>com.sun.java.swing.plaf.windows.WindowsLookAndFeel</theme> </main> </configuration>

For text file [Configuration] Theme=com.sun.java.swing.plaf.windows.WindowsLookAndFeel

Thanks alot!

Solution 1

For parsing the XML use XPath[^] and for the text file based approach use Java Property Riles[^].

Hope that helps a bit.

Cheers!

Thanks im going to try it and tell you if it works or not!

Edited: See i tried using DOM Parser and it works but the thing would be that its not static meaning i cannot use it globally!

import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.DocumentBuilder;
import org.w3c.dom.Document;
import org.w3c.dom.NodeList;
import org.w3c.dom.Node;
import org.w3c.dom.Element;
import java.io.File;
 
public class ReadXMLFile {
 
 public static void main(String argv[]) {
 
 try {
 
    File fXmlFile = new File("file.xml");
    DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
    Document doc = dBuilder.parse(fXmlFile);
    doc.getDocumentElement().normalize();
 
    System.out.println("Root element :" + doc.getDocumentElement().getNodeName());
    NodeList nList = doc.getElementsByTagName("Configuration");
    System.out.println("-----------------------");
 
    for (int temp = 0; temp < nList.getLength(); temp++) {
 
       Node nNode = nList.item(temp);	    
       if (nNode.getNodeType() == Node.ELEMENT_NODE) {
 
          Element eElement = (Element) nNode;
 
          System.out.println("Theme : "  + getTagValue("theme",eElement));
 
        }
    }
  } catch (Exception e) {
    e.printStackTrace();
  }
 }
 
 private static String getTagValue(String sTag, Element eElement){
    NodeList nlList= eElement.getElementsByTagName(sTag).item(0).getChildNodes();
    Node nValue = (Node) nlList.item(0); 
 
    return nValue.getNodeValue();    
 }
 
}
