public static XMLInputFactory newInstance()
                                   throws FactoryConfigurationError
```
    Creates a new instance of the factory in exactly the same manner as the newFactory() method.
    
    抛出:
    
    FactoryConfigurationError - if an instance of this factory cannot be loaded
  - newFactory
```
public static XMLInputFactory newFactory()
                                  throws FactoryConfigurationError
```
    Create a new instance of the factory.
    This static method creates a new factory instance. This method uses the following ordered lookup procedure to determine the XMLInputFactory implementation class to load:
    - Use the ohos.javax.xml.stream.XMLInputFactory system property.
    - Use the properties file "lib/stax.properties" in the JRE directory. This configuration file is in standard java.util.Properties format and contains the fully qualified name of the implementation class with the key being the system property defined above.
    - Use the service-provider loading facilities, defined by the ServiceLoader class, to attempt to locate and load an implementation of the service using the default loading mechanism: the service-provider loading facility will use the current thread's context class loader to attempt to load the service. If the context class loader is null, the ClassLoader#getSystemClassLoader() will be used.
    - Otherwise, the system-default implementation is returned.
    Once an application has obtained a reference to a XMLInputFactory it can use the factory to configure and obtain stream instances.
    
    Note that this is a new method that replaces the deprecated newInstance() method. No changes in behavior are defined by this replacement method relative to the deprecated method.
    抛出:
    
    FactoryConfigurationError - in case of service configuration error or if the implementation is not available or cannot be instantiated.
  - newInstance
```
@Deprecated
public static XMLInputFactory newInstance(String factoryId,
                                          ClassLoader classLoader)
                                   throws FactoryConfigurationError
```
    已过时。 This method has been deprecated to maintain API consistency. All newInstance methods have been replaced with corresponding newFactory methods. The replacement newFactory(java.lang.String,java.lang.ClassLoader) method defines no changes in behavior.
    
    Create a new instance of the factory
    
    参数:
    
    factoryId - Name of the factory to find, same as a property name
    
    classLoader - classLoader to use
    
    返回:
    
    the factory implementation
    
    抛出:
    
    FactoryConfigurationError - if an instance of this factory cannot be loaded

                                         ClassLoader classLoader)
                                  throws FactoryConfigurationError
```
    Create a new instance of the factory. If the classLoader argument is null, then the ContextClassLoader is used.
    This method uses the following ordered lookup procedure to determine the XMLInputFactory implementation class to load:
    - Use the value of the system property identified by factoryId.
    - Use the properties file "lib/stax.properties" in the JRE directory. This configuration file is in standard java.util.Properties format and contains the fully qualified name of the implementation class with the key being the given factoryId.
    - If factoryId is "ohos.javax.xml.stream.XMLInputFactory", use the service-provider loading facilities, defined by the ServiceLoader class, to attempt to locate and load an implementation of the service using the specified ClassLoader. If classLoader is null, the default loading mechanism will apply: That is, the service-provider loading facility will use the current thread's context class loader to attempt to load the service. If the context class loader is null, the ClassLoader#getSystemClassLoader() will be used.
    - Otherwise, throws a FactoryConfigurationError.
    Note that this is a new method that replaces the deprecated newInstance(String factoryId, ClassLoader classLoader) method. No changes in behavior are defined by this replacement method relative to the deprecated method.
    参数:
    
    factoryId - Name of the factory to find, same as a property name
    
    classLoader - classLoader to use
    
    返回:
    
    the factory implementation
    
    抛出:
    
    FactoryConfigurationError - in case of service configuration error or if the implementation is not available or cannot be instantiated.
