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。是否有任何框架可以实现这一目标?
只是我的意思的一个例子
从我要解析的XSD:
<xsd:import namespace="..." schemaLocation="anotherFile.xsd">
<xsd:element ref="anElement" />
从已解析文件中导入的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>
所以,我想要的是当我通过某种内联或其他东西解析原始xsd时,可以访问导入的xsd中的元素: - )
这有可能吗?

是的,您只需要实现一个能够从您指定的模式位置读取的LSResourceResolver类:
/**
* 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,它在类路径的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;
}
}
}

看起来你需要JAXB来将你的模式(包括导入的模式)放到Java类中。

当XSD文件位于local / src / main / resources目录或打包在jar中时,这对我有用:
final SchemaFactory sf = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
final URL url = this.getClass().getClassLoader().getResource("META-INF/parent.xsd");
final Schema schema = sf.newSchema(url);
parent.xsd已包含&#34; kid.xsd&#34; - 两个XSD文件都在同一目录下
