使用Java 7，您可以遵循包描述中提供的文档。

// create a SchemaFactory capable of understanding WXS schemas SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI); // load a WXS schema, represented by a Schema instance Source schemaFile = new StreamSource(new File("mySchema.xsd")); Schema schema = factory.newSchema(schemaFile); // create a Validator instance, which can be used to validate an instance document Validator validator = schema.newValidator(); // validate the DOM tree try { validator.validate(new StreamSource(new File("instance.xml")); } catch (SAXException e) { // instance document is invalid! }

我们使用ant构建我们的项目，所以我们可以使用schemvalidate任务来检查我们的配置文件:

<schemavalidate> 
    <fileset dir="${configdir}" includes="**/*.xml" />
</schemavalidate>

现在淘气的配置文件将失败我们的构建!

使用Woodstox，配置StAX解析器以根据您的模式进行验证并解析XML。

如果异常被捕获，则XML无效，否则有效:

// create the XSD schema from your schema file
XMLValidationSchemaFactory schemaFactory = XMLValidationSchemaFactory.newInstance(XMLValidationSchema.SCHEMA_ID_W3C_SCHEMA);
XMLValidationSchema validationSchema = schemaFactory.createSchema(schemaInputStream);

// create the XML reader for your XML file
WstxInputFactory inputFactory = new WstxInputFactory();
XMLStreamReader2 xmlReader = (XMLStreamReader2) inputFactory.createXMLStreamReader(xmlInputStream);

try {
    // configure the reader to validate against the schema
    xmlReader.validateAgainst(validationSchema);

    // parse the XML
    while (xmlReader.hasNext()) {
        xmlReader.next();
    }

    // no exceptions, the XML is valid

} catch (XMLStreamException e) {

    // exceptions, the XML is not valid

} finally {
    xmlReader.close();
}

注意:如果您需要验证多个文件，您应该尝试重用您的XMLInputFactory和XMLValidationSchema，以最大化性能。

对在线模式进行验证

Source xmlFile = new StreamSource(Thread.currentThread().getContextClassLoader().getResourceAsStream("your.xml"));
SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = factory.newSchema(Thread.currentThread().getContextClassLoader().getResource("your.xsd"));
Validator validator = schema.newValidator();
validator.validate(xmlFile);

对本地模式进行验证

使用Java进行离线XML验证

下面是如何使用Xerces2来实现这一点。这方面的教程在这里(req。注册)。
