我已经通过Maven安装了Xerces:
<dependencies>
<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.11</version>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.jdom</groupId>
<artifactId>jdom</artifactId>
<version>2.0.2</version>
</dependency>
<dependency>
<groupId>xerces</groupId>
<artifactId>xercesImpl</artifactId>
<version>2.11.0</version>
</dependency>
</dependencies>
我接着尝试了Xerces FAQ中提供的示例代码,以在版本1.1中校验XML文件是否符合模式。这是我的代码:
private static void validateFile(File xmlFile, File xsdFile) throws SAXException, IOException
{
// 1. Lookup a factory for the W3C XML Schema language
SchemaFactory factory = SchemaFactory.newInstance("http://www.w3.org/XML/XMLSchema/v1.1");
// 2. Compile the schema.
File schemaLocation = xsdFile;
Schema schema = factory.newSchema(schemaLocation);
// 3. Get a validator from the schema.
Validator validator = schema.newValidator();
// 4. Parse the document you want to check.
Source source = new StreamSource(xmlFile);
// 5. Check the document
try
{
validator.validate(source);
System.out.println(xmlFile.getName() + " is valid.");
}
catch (SAXException ex)
{
System.out.println(xmlFile.getName() + " is not valid because ");
System.out.println(ex.getMessage());
}
}
代码只会产生这个异常:
java.lang.IllegalArgumentException: No SchemaFactory that implements the schema language specified by: http://www.w3.org/XML/XMLSchema/v1.1 could be loaded
at javax.xml.validation.SchemaFactory.newInstance(SchemaFactory.java:204)
at example.xml.XSDValidator.validateFile(XSDValidator.java:65)
似乎我没有成功地配置/安装Xerces。请帮助我让它工作起来,XML文件要求我使用1.1版本的模式,我已经有了一个正常的1.0版本验证器,但是对于这个版本我遇到了很大的问题。感谢每一个提示!
