我正在使用 Jing API 进行 RelaxNG 和 xml 验证。我无法验证我指定松弛的字符串的长度。我已经用 java 编写了以下独立代码。在松弛文件中，我将 minLength 验证指定为 3，在代码中我传递空字符串仍然 jing api 没有抛出任何错误。字符串的验证没有发生。我正在使用 Jing API。

我的代码：

 public static void main(String[] args) throws JAXBException, IOException, SAXException, IncorrectSchemaException, TransformerConfigurationException, TransformerException, TransformerFactoryConfigurationError {
        OBJ006 obj006 = new OBJ006();
        obj006.setMyInput("");
        JAXBContext jc = JAXBContext.newInstance(OBJ006.class);
        Marshaller marshaller = jc.createMarshaller();
        marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
        JAXBElement<OBJ006> rootElement =
            new JAXBElement<OBJ006>(new QName("obj006"),
            OBJ006.class,
            obj006);
        StringWriter xmlFile = new StringWriter();
        marshaller.marshal(rootElement, xmlFile);
        String encodedxml = new String(xmlFile.toString().getBytes());
       System.out.println(encodedxml);

       //Get Schema
       File file = new File("C:/XML/Cardinalities/myRelaxNG.xml");
       FileInputStream fileInput = new FileInputStream(file);
       InputSource schemaSource = new InputSource(fileInput);

       SchemaReader schemaReader = new AutoSchemaReader();
       Schema schema = schemaReader.createSchema(schemaSource, PropertyMap.EMPTY);
       ErrorHandler errorHandler = new ErrorHandlerImpl();
       PropertyMapBuilder builder = new PropertyMapBuilder();
       builder.put(ValidateProperty.ERROR_HANDLER, errorHandler);

       Validator validator = schema.createValidator(builder.toPropertyMap());

       TransformerFactory.newInstance().newTransformer()
       .transform(new StreamSource(new ByteArrayInputStream(encodedxml.getBytes())),
               new SAXResult(validator.getContentHandler()));






}

2.MyRelaxNG.xml

<?xml version="1.0"?>
<!-- Converted to RelaxNG using http://debeissat.nicolas.free.fr/XSDtoRNG.php -->
<rng:grammar xmlns:rng="http://relaxng.org/ns/structure/1.0"
    ns="" datatypeLibrary="http://www.w3.org/2001/XMLSchema-datatypes">
        <rng:start combine="choice">
        <rng:ref name="obj006" />
    </rng:start>
    <rng:define name="obj006">
        <rng:element name="obj006">
            <rng:ref name="obj006ref" />
        </rng:element>
    </rng:define>
            <rng:define name="obj006ref">  
         <rng:element name="myInput">
            <rng:data type="string">
              <param name="minlength">3</param>
              </rng:data>
         </rng:element>


        </rng:define>

    </rng:grammar>

3.）我的程序的输出：

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<obj006>
    <myInput></myInput>
</obj006>

您需要像这样指定参数：

<rng:param name="minLength">3</rng:param>

你有它的方式，你有它，<param>它不在 Relax NG 命名空间中，因此被忽略了。此外，您有，minlength但参数名称minLength带有大写“L”。
