          DOMParser dom = new DOMParser();
          try
               dom.parse("nitinxml.xml");
               System.out.println("NOOOOO error during parsing");
          catch(Exception e)

Answer 1

i did just as u said ...
i added the following code before parsing the document
import org.apache.xerces.parsers.DOMParser;
class trail
     public static void main(String arg[])
          DOMParser dom = new DOMParser();
          try
               dom.setFeature("http://xml.org/sax/features/validation", true);
               dom.parse("nitinxml.xml");
               System.out.println("NOOOOO error during parsing");
          catch(Exception e)
               System.out.println("error during parsing "+e.getMessage());
but still the dtd is not getting applied ......
i concluded that the dtd is not getting applied because the parsing does not throw any error even when the XML does not follow the rules in the inline DTD ...
any further help would be appreciated a lot ..
any site where i can get the working of XERSER parser
i am a novice in the filed of XML ....:(:(:(
thx in advance .....
