XMLReader

Synopsis

This interface defines the methods that must be implemented by a SAX2 XML parser. Since it is an interface, XMLReader cannot define a constructor for creating an XMLReader. To obtain an XMLReader, object, you can instantiate some implementation-specific class that implements this interface. Alternatively, you can keep your code independent of any specific parser implementation by using the SAXParserFactory and SAXParser classes of the javax.xml.parsers package. See those classes for more details. Note that the XMLReader interface has no relationship to the java.io.Reader class or any other character stream classes.

Once you have obtained an XMLReader instance, you must register handler objects on it, so that it can invoke methods on those handlers to notify your application of the results of its parsing. All applications should register a ContentHandler and an ErrorHandler with setContentHandler( ) and setErrorHandler( ). Some applications may also want to register an EntityResolver and/or a DTDHandler. Applications can also register DeclHandler and LexicalHandler objects from the org.xml.sax.ext package, if the parser implementation supports these extension handler interfaces. DeclHandler and LexicalHandler objects are registered with setProperty( ), as explained below.

In addition to registering handler objects for an XMLReader, you may also want to configure the behavior of the parser using setFeature( ) and setProperty( ). Features and properties are both ...
