Examples of javax.xml.parsers.SAXParserFactory

javax.xml.parsers.SAXParserFactory
Defines a factory API that enables applications to configure and obtain a SAX based parser to parse XML documents.
An implementation of the SAXParserFactory class is NOT guaranteed to be thread safe. It is up to the user application to make sure about the use of the SAXParserFactory from more than one thread. Alternatively the application can have one instance of the SAXParserFactory per thread. An application can use the same instance of the factory to obtain one or more instances of the SAXParser provided the instance of the factory isn't being used in more than one thread at a time.
The static newInstance method returns a new concrete implementation of this class. @since JAXP 1.0 @version 1.0
