Remove all attributes by first making a copy of the attribute names and then using the list to remove the attributes:

        

import java.io.File;

import javax.xml.parsers.DocumentBuilderFactory;

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

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 element = doc.getElementById("key1");

    NamedNodeMap attrs = element.getAttributes();
    String[] names = new String[attrs.getLength()];
    for (int i = 0; i < names.length; i++) {
      names[i] = attrs.item(i).getNodeName();
    }
    for (int i = 0; i < names.length; i++) {
      attrs.removeNamedItem(names[i]);
    }
  }
}
