Re: Difficulties with Java

Consider creating your own utility/helper classes.
Then outputing an xml file to the console could *simply* be:

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

public class DomTest
{
    public static void main(String[] args)
    throws Exception
    {
        DocumentBuilder db =
DocumentBuilderFactory.newInstance().newDocumentBuilder();
        InputStream is = new FileInputStream("test.xml");
        Document doc = db.parse(is);
        is.close();
        System.out.println(DomUtil.toString(doc));
    }
}

This is the utility class:

// DomUtil.java
import java.io.*;
import javax.xml.transform.*;
import javax.xml.transform.stream.*;
import javax.xml.transform.dom.*;
import org.w3c.dom.*;

public class DomUtil
{
    public static String toString(Document doc)
    throws Exception
    {
        StringWriter sw = new StringWriter();
        TransformerFactory tf = TransformerFactory.newInstance();
        Transformer t = tf.newTransformer();
        t.setOutputProperty(OutputKeys.METHOD, "xml");
        if (doc.getXmlEncoding() != null)
            t.setOutputProperty(OutputKeys.ENCODING,
doc.getXmlEncoding());
        t.setOutputProperty(OutputKeys.INDENT, "yes");
        t.transform(new DOMSource(doc), new StreamResult(sw));
        return sw.toString();
    }
}
