XML文件校验

已经找到解决方案，但是digester好像不行。
dom4j解决方案：

Java代码

SAXReader reader = new SAXReader();

        reader.setValidation(true);
        try {
            reader.setFeature("http://xml.org/sax/features/validation", true);
            reader.setFeature("http://apache.org/xml/features/validation/schema", true);

            reader.setProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",
                                            "d://requestinfo.xsd");

            XMLErrorHandler errorHandler = new XMLErrorHandler();
            reader.setErrorHandler(errorHandler);

            Document document = reader.read("d://requestInfo.xml");
            XMLWriter writer = new XMLWriter(OutputFormat.createPrettyPrint());
            if (errorHandler.getErrors().hasContent()) {
                    writer.write(errorHandler.getErrors());
            } else {
                    System.out.println("validate success.");
            }
        } catch (SAXException e) {
            e.printStackTrace();
        } catch (DocumentException e) {
            e.printStackTrace();
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

    }
================================================================不知道你用是不是jdk1.5以上，如果是可以试试jdk提供的Schema，我直接拷贝项目中的代码了。  
     public class DefaultSchemaValidator implements SchemaValidator {

    private InputStream schemaStream;

    /**
     * 构造函数
     * @param schemaStream schema文件输入流
     */
    public DefaultSchemaValidator(InputStream schemaStream) {
    this.schemaStream = schemaStream;
    }

    /**
     * 构造函数
     * @param clz
     * @param schemaFile schema文件
     */
    public DefaultSchemaValidator(Class clz, String schemaFile) {
    this.schemaStream = clz.getResourceAsStream(schemaFile);
    }

    public DefaultSchemaValidator(ClassLoader classLoader, String schemaFile) {
    this.schemaStream = classLoader.getResourceAsStream(schemaFile);
    }

    public void validate(InputStream xmlStream, ErrorHandler errorHandler) throws SAXException, IOException {
    Schema schema = createSchema(schemaStream);
    Validator validator = schema.newValidator();
    validator.setErrorHandler(errorHandler);
    validator.validate(new StreamSource(xmlStream));
    }

    public void validate(InputStream xmlStream) throws SAXException, IOException {
    validate(xmlStream, new DefaultErrorHandler());
    }

    /**
         * 验证给定的xml是否合法
         *
         * @return
         * @throws SAXException
         */
    protected Schema createSchema(InputStream schemaStream) throws SAXException {
    SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
    return schemaFactory.newSchema(new StreamSource(schemaStream));
    }
