* <p><strong>Note:</strong> This class is designed to work with the now-deprecated
|
|
* SAX1 {@link org.xml.sax.Parser Parser} class. SAX2 applications should use
|
|
* {@link org.xml.sax.helpers.XMLReaderFactory XMLReaderFactory} instead.</p>
|
|
*
|
|
* <p>ParserFactory is not part of the platform-independent definition
|
|
* of SAX; it is an additional convenience class designed
|
|
* specifically for Java XML application writers. SAX applications
|
|
* can use the static methods in this class to allocate a SAX parser
|
|
* dynamically at run-time based either on the value of the
|
|
* `org.xml.sax.parser' system property or on a string containing the class
|
|
* name.</p>
|
|
*
|
|
* <p>Note that the application still requires an XML parser that
|
|
* implements SAX1.</p>

|
