Determining If an Attribute Was Supplied in a DOM Element

        

import java.io.File;

import javax.xml.parsers.DocumentBuilderFactory;

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

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");
    Attr attr = (Attr) element.getAttributeNode("attrName");
    boolean wasSpecified = attr != null && attr.getSpecified();
  }
}
