There are three things you should do: Associate the source XML document with its DTD with a doctype declaration after the XML declaration: Note: The DOCTYPE root must match the root element in the source XML. SetValidating to true on the DocumentBuilderFactory Provide an org.xml.sax. ErrorHandler instance to the DocumentBuilder using setErrorHandler Here's a complete example: DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance(); domFactory.

SetValidating(true); DocumentBuilder builder = domFactory. NewDocumentBuilder(); builder. SetErrorHandler(new ErrorHandler() { @Override public void error(SAXParseException exception) throws SAXException { // do something more useful in each of these handlers exception.printStackTrace(); } @Override public void fatalError(SAXParseException exception) throws SAXException { exception.printStackTrace(); } @Override public void warning(SAXParseException exception) throws SAXException { exception.printStackTrace(); } }); Document doc = builder.

Parse("employee. Xml"); Source document: E-001 Vinod [email protected].

Thanks lwburk! But I don't allow to change in original source xml file. – Sachin Jalkotkar Jan 4 at 4:41.

You just need to read the files and report the exceptions, if any. Here is a SAX parser example you can rely upon. In order to validate your XML and DTD you just need to setValidating: DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance(); dbf.

SetValidating(true); // since the default value is false Also declare the DTD usage in your XML file.

2 Document root element "Employee", must match DOCTYPE root "employee". – lwburk Jan 3 at 19:37 Of course Employee! Thank you... – Costis Aivalis Jan 3 at 20:05 +1 - Thanks for fixing.

You can validate an xml with an xsd schema using JAXB api. I am not sure if you can do the same for DTD.

This should be a comment. – lwburk Jan 3 at 19:30.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
