SAXParserFactory newInstance() Method
Description
The Javax.xml.parsers.SAXParserFactory.newInstance() method obtains a new instance of a SAXParserFactory. This static method creates a new factory instance This method uses the following ordered lookup procedure to determine the SAXParserFactory implementation class to load −
Use the javax.xml.parsers.SAXParserFactory system property.
Use the properties file "lib/jaxp.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. The jaxp.properties file is read only once by the JAXP implementation and it's values are then cached for future use. If the file does not exist when the first attempt is made to read from it, no further attempts are made to check for its existence. It is not possible to change the value of any property in jaxp.properties after it has been read for the first time.
Use the Services API (as detailed in the JAR specification), if available, to determine the classname. The Services API will look for a classname in the file META-INF/services/javax.xml.parsers.SAXParserFactory in jars available to the runtime.
Platform default SAXParserFactory instance.
Once an application has obtained a reference to a SAXParserFactory it can use the factory to configure and obtain parser instances.
Declaration
Following is the declaration for Javax.xml.parsers.SAXParserFactory.newInstance() method
public static SAXParserFactory newInstance()
Parameters
NA
Return Value
This method returns a new instance of a SAXParserFactory.
Exception
FactoryConfigurationError − if the implementation is not available or cannot be instantiated.
Example
The following example shows the usage of Javax.xml.parsers.SAXParserFactory.newInstance() method.
package com.tutorialspoint; import javax.xml.parsers.SAXParserFactory; public class SAXParserFactoryDemo { public static void main(String[] args) { // create a new SAXParserFactory SAXParserFactory factory = SAXParserFactory.newInstance(); try { // check if our factory parsers are XInclude aware System.out.println("" + factory.isXIncludeAware()); // change this setting factory.setXIncludeAware(true); // check if our factory parsers are XInclude aware System.out.println("" + factory.isXIncludeAware()); } catch (Exception ex) { ex.printStackTrace(); } } }
If we compile the code and execute it, this will produce the following result −
false true
