If you use a DOM parser explicitly for validation, you will definitely instantiate a DOM tree. Is is a case of just creating the Error Handler and associating it with the validator? // parse an XML document into a DOM tree Document Builder parser = Document Builder Instance()Document Builder(); Document document = parser.parse(new File("instance.xml")); // create a Schema Factory capable of understanding WXS schemas Schema Factory factory = Schema Instance(XMLConstants. If I use an Error Handler (own class that implements Error Handler) instead, it recognizes all errors, but the try-catch-block of validator.validate does not throw any Exception..
W3C_XML_SCHEMA_NS_URI); // load a WXS schema, represented by a Schema instance Source schema File = new Stream Source(new File("my Schema.xsd")); Schema schema = Schema(schema File); // create a Validator instance, which can be used to validate an instance document Validator validator = Validator(); // validate the DOM tree try catch (SAXException e) Working this way, a SAXException would be thrown at the first error in the xml-file and stops then the validation. How do I recognize an error in the class that invokes the validate-method of my validator? is probably a network location, so it'll go out and hit the network with each and every validation, not always optimal.

Errors in XML documents will stop your XML applications.
The W3C XML specification states that a program should stop processing an XML document if it finds an error.
This will start creating DOM objects as it parses the document - wasteful if you aren't going to use them.
You should not use the DOMParser to validate a document (unless your goal is to create a document object model anyway).
The validator checks for well formedness first, meaning that your XML file must be parsable using a DOM/SAX parser, and only then does it validate your XML against the XML Schema.
The validator will report fatal errors, non-fatal errors and warnings.Permissions beyond the scope of this license may be available at [email protected] A JAXP implementation could legally use a DOM parser in this case, but there is no reason to. Set Error Handler() as in the example in this SO question stackoverflow.com/questions/4864681/…? Sun's JDK 6 uses SAX parser with a Stream Source. @ziggy - this is an implementation detail of the JAXP implementation.Many formation errors are easy to spot in the syntax highlighting, so you can easily correct obvious errors on-the-fly.
