Java EE (Java Enterprise Edition) General Discussion

Hi!
I need to read XML with the Xerces DOM Parser and also validate it against prepared XSD. So far, I have this:

import java.io.IOException;

import org.w3c.dom.Document;
import org.xml.sax.SAXException;

import com.sun.org.apache.xerces.internal.parsers.DOMParser;


public class XMLParser {

  public XMLParser(String inputFile) {
    DOMParser parser = new DOMParser();
    try {
      parser.parse(inputFile);
      Document document = parser.getDocument();
    } catch (IOException e) {
      System.err.println (e);
    }
    catch (SAXException e) {
      e.printStackTrace();
    }
  }
}

Now I tried to find how to do the validation, but without success. I believe it should be done by setting

parser.setFeature();

but I don't now, what should be in the argument. Or am I wrong and there is different way? Thanks!
