Having XML readerclass return values, but which way is best?

[Kenjitsuka]

Hello all,

I wrote a class a while back, which gets a specific set of values from specific XML files. It can then print the results in Console and it works just fine.
But of course I didn't make a class to print to console ;)

I need to get the values into a database. There is a separate class that handles the db input.
What I'd like to ask you guys is, what way is the simplest or otherwise best?
I was thinking of a String[], but am having trouble returning anything at all...

For as far as I know the return statement should be outside the current method (after the main method ends), but then I can't get the values from inside the main method that reads them from the XML (the values from the Nodelist 'nodes'). I was thinking of using a bunch of global variables, but it seems a rather awkward thing to do.

Maybe split the whole thing into two methods; one for reading which can be called from another class and a second method that can be read by the database-put class?

I'm not a very good coder, let alone experienced, so I'd value your input highly! :)

Below is the class as it is now:

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

public class xmlGrabber {

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

    DocumentBuilderFactory domFactory = 
    DocumentBuilderFactory.newInstance();
          domFactory.setNamespaceAware(true); 
    DocumentBuilder builder = domFactory.newDocumentBuilder();
    String docuInvoer = "C:/temp/document.xml";
    Document doc = builder.parse(docuInvoer);
    XPath xpath = XPathFactory.newInstance().newXPath();
       // XPath Query for showing all nodes value
    XPathExpression expr = xpath.compile("//@fieldvalue");

    Object result = expr.evaluate(doc, XPathConstants.NODESET);
    NodeList nodes = (NodeList) result;
    for (int i = 1; i < 24; i++) {
     System.out.println(nodes.item(i).getNodeValue()); 
     //String bla = nodes.item(1).getNodeValue(); 
    
    }
  }
}
