只是想知道是否有任何方法可以解析xsd文件和同时在原始xsd中导入的xsd，因此我可以直接访问导入的xsd中的元素。是否有任何框架使之成为可能？
只是我意思的一个例子
从我要解析的XSD:<xsd:import namespace="..." schemaLocation="anotherFile.xsd"><xsd:element ref="anElement" />
从解析文件中导入的XSD<xsd:element name="anElement"><xsd:simpleType><xsd:restriction base="xsd:string"> <xsd:enumeration value="THIS" /><xsd:enumeration value="IS" /> <xsd:enumeration value="THE" /><xsd:enumeration value="ELEMENTS" /><xsd:enumeration value="I" /><xsd:enumeration value="WANT" /><xsd:enumeration value=":-)" /></xsd:restriction></xsd:simpleType></xsd:element>
因此，我想要通过某种内联或其他方式解析原始xsd时访问导入的xsd中的元素:-)
这有可能吗？
最佳答案
是的，您只需要实现一个LSResourceResolver类即可读取指定的架构位置:
/**
* This function validates a DomResult. T
*
* @param domResult
* @param schemaFile path to the schmea file to validate against.
* @throws org.xml.sax.SAXException
* @throws java.io.IOException
*
*/
protected void validateDomResult(DOMResult domResult, String schemaFile) throws SAXException, IOException, Exception {
Schema schema = createSchema(schemaFile);
javax.xml.validation.Validator validator = schema.newValidator();
ErrorHandler mySchemaErrorHandler = new LoggingErrorHandler();
validator.setErrorHandler(mySchemaErrorHandler);
DOMSource domSource = new DOMSource(domResult.getNode());
validator.validate(domSource);
if (((LoggingErrorHandler) mySchemaErrorHandler).isError()) {
throw new Exception("Validation Error");
}
}
/**
*
* @param baseSchemaFilePath
* @return
* @throws java.lang.Exception
*
*/
protected Schema createSchema(String baseSchemaFilePath) throws Exception {
SchemaFactory factory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
LSResourceResolver resourceResolver = (LSResourceResolver) new LocalSchemaLSResourceResolver();
factory.setResourceResolver(resourceResolver);
Schema schema = factory.newSchema(new File(baseSchemaFilePath));
return schema;
}
这是一个简单的LSResourceResolver实现，该实现在类路径的xsd目录中查找模式:
public class LocalSchemaLSResourceResolver implements LSResourceResolver{
protected final Log logger = LogFactory.getLog(getClass());
public LSInput resolveResource(String type, String namespaceURI, String publicId, String systemId, String baseURI) {
LSInput input = new DOMInputImpl();
try {
FileInputStream fis = new FileInputStream(new File("classpath:xsd/" + systemId));
input.setByteStream(fis);
return input;
} catch (FileNotFoundException ex) {
logger.error("File Not found", ex);
return null;
}
}
}
