David, sempre que reportar um erro, tente seguir estes procedimentos:

:arrow: Jogue o erro que está acontecendo;

:arrow: Mostre todo o código envolvido (.java, .jsp, .xml, .*);

:arrow: Tente descrever o tipo de ambiente (SO, JVM, Classpath…) em que o aplicativo está sendo testado.

import com.sun.xml.tree.*;
import org.w3c.dom.*;

public class XML {

	public static void main ( String args[] )
	{
		try {
			String url = "file://e:\david\xml\teste.xml";
			System.out.println( url );
			Document doc = XmlDocument.createXmlDocument( url );
			doc.getDocumentElement().normalize();

			NodeList node1, node2;
			Node table;
			Element E;
			node1 = doc.getElementsByTagName( "table" );
			int qde = node1.getLength();
			System.out.println( qde + " " + url );
			for ( int i = 0; i < qde; i++ ) {
				table = node1.item( i );
				E = ( Element ) table;
				node2 = E.getElementsByTagName( "field" );
				node2 = node2.item( 0 ).getChildNodes();
				System.out.println( "Campo: " + node2.item(0).getNodeValue() );
