W3C_XML_SCHEMA_NS_URI); Schema schema = schema Schema(); Validator validator = Validator(); Resource Resolver(new LSResource Resolver() ); validator.validate(xml File); // 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.. validation errors) and "fatal errors" (well-formedness errors). But a validation error does not stop it : you have to explicitly throw an exception.

But then again, validating XML against XSD files is a rather heavy weight problem.

You can then use these objects to build an XML document based on this schema.

It has built-in support for schema validation, and can convert Java objects to an XML document and vice-versa. In debian squeeze it is located in the package "libxerces-c-samples". As far as libraries goes, pretty much the de-facto standard is Xerces2 which has both C and Java versions.

You should not use the DOMParser to validate a document (unless your goal is to create a document object model anyway).

W3C_XML_SCHEMA_NS_URI); try catch (SAXException e) catch (IOException e) but you could just as easily validate against a local file.
