XML Node to String in Java

Question

I came across this piece of Java function to convert an XML node to a Java String representation:

private String nodeToString(Node node) {
StringWriter sw =

All important has already been said. I tried to compile the following code.

import java.io.ByteArrayInputStream;
import java.io.InputStream;
import java.io.StringWriter;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.transform.OutputKeys;
import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerException;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.dom.DOMSource;
import javax.xml.transform.stream.StreamResult;

import org.w3c.dom.Document;
import org.w3c.dom.Node;

public class Test {

  public static void main(String[] args) throws Exception {

    String s = 
      "
" +
      "  " +
      "    " +
      "  " +
      "  Most other kinds of bees live alone instead of in a colony." +
      "  These bees make tunnels in wood or in the ground." +
      "  The queen makes her own nest." +
      "
";
    InputStream is = new ByteArrayInputStream(s.getBytes());

    DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
    DocumentBuilder db = dbf.newDocumentBuilder();
    Document d = db.parse(is);

    Node rootElement = d.getDocumentElement();
    System.out.println(nodeToString(rootElement));

  }

  private static String nodeToString(Node node) {
    StringWriter sw = new StringWriter();
    try {
      Transformer t = TransformerFactory.newInstance().newTransformer();
      t.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
      t.setOutputProperty(OutputKeys.INDENT, "yes");
      t.transform(new DOMSource(node), new StreamResult(sw));
    } catch (TransformerException te) {
      System.out.println("nodeToString Transformer Exception");
    }
    return sw.toString();
  }

}

And it produced the following output:

          Most other kinds of bees live alone instead of in a colony.  These bees make tunnels in wood or in the ground.  The queen makes her own nest.

You can further tweak it by yourself. Good luck!
