The former technique will cause parsers to use the new validation API; the latter will cause parsers to use their own internal validation facilities.
That documentation contains more detailed, developer-targeted descriptions, with conceptual overviews, definitions of terms, workarounds, and working code examples.

The input document contains an extra attribute which has not been defined in the XML Schema, this shows that the XML Schema has been used for the validation.
When using this XML Schema to validate the input XML document, the following error gets reported: ) as defined below has been used in the code examples to validate the input document.
With the valid XSD file we can validate the XML file against this schema.Both, Java and XML are spread widely and used intensively.This post sheds some light onto the possibilities on validating XML files with the JAVA API.Turning on both of these options simultaneously will cause either redundant behavior or error conditions.Submit a bug or feature For further API reference and developer documentation, see Java SE Documentation. Or you can set your own via set Resource Resolver, ex: Source xml File = new Stream Source(xml File Location); Schema Factory schema Factory = Schema Factory Instance(XMLConstants.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.This might depends on the library you use but googling around with "how to validate xml file in java" gave me these results where you might find your answer: first interesting result second interesting result Validator v = Language(Languages.// 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. 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.
