根据XSD验证XML

Question

我需要使用给定的XSD文件验证XML文件.如果验证正常,我只需要方法返回true,否则返回false.

Answer 1

返回true或false(也不需要任何外部库):

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;
    }
}

Answer 2

XMLUnit有一些很好的类来做到这一点，在他们的 README 文件中有一个例子：

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();
