Validating XML against XSD [duplicate]

Returns simply true or false (also you don't need any external library):

static boolean validateAgainstXSD(InputStream xml, InputStream xsd){    try    {        SchemaFactory factory =             SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);        Schema schema = factory.newSchema(new StreamSource(xsd));        Validator validator = schema.newValidator();        validator.validate(new StreamSource(xml));        return true;    }    catch(Exception ex)    {        return false;    }}

XMLUnit has some nice classes to do this, there is an example in their README file:

Validator v = Validator.forLanguage(Languages.W3C_XML_SCHEMA_NS_URI);v.setSchemaSources(Input.fromFile("local.xsd").build());ValidationResult result = v.validateInstance(new StreamSource(new File("local.xml")));return result.isValid();

public boolean validate() {  DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();  factory.setValidating(true);  factory.setAttribute(        "http://java.sun.com/xml/jaxp/properties/schemaLanguage",        "http://www.w3.org/2001/XMLSchema");  factory.setAttribute(        "http://java.sun.com/xml/jaxp/properties/schemaSource",        "http://domain.com/mynamespace/mySchema.xsd");  Document doc = null;  try {    DocumentBuilder parser = factory.newDocumentBuilder();    doc = parser.parse("data.xml");    return true;  } catch (Exception e) {    return false;  }}
