Getting the Root Element in a DOM Document

        

import java.io.File;

import javax.xml.parsers.DocumentBuilderFactory;

import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.NodeList;

public class Main {
  public static void main(String[] argv) throws Exception{
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    factory.setValidating(true);

    factory.setExpandEntityReferences(false);

    Document doc = factory.newDocumentBuilder().parse(new File("filename"));

    Element root = null;

    NodeList list = doc.getChildNodes();
    for (int i = 0; i < list.getLength(); i++) {
      if (list.item(i) instanceof Element) {
        root = (Element) list.item(i);
        break;
      }
    }
    root = doc.getDocumentElement();
  }
