No validating saxparser implementation available

You see the data as it streams in, but you cannot go back to an earlier position or leap ahead to a different position.In general, such parsers work well when you simply want to read data and have the application act on it.SAX is an event-driven model (you provide the callback methods, and the parser invokes them as it reads the XML data), and that makes it harder to visualize.Finally, you cannot "back up" to an earlier part of the document, or rearrange it, any more than you can back up a serial data stream or rearrange characters you have read from that stream.

The following code in the when it encounters problems, and defines the command-line options which are required to tell the application the name of the XML file to be processed.

The parser can generate three kinds of errors: a fatal error, an error, and a warning.

When a fatal error occurs, the parser cannot continue.

Both of these public void start Document() throws SAXException public void start Element(String namespace URI, String local Name, String q Name, Attributes atts) throws SAXException public void end Document() throws SAXException method defined in Setting Up I/O.

You could start using your parser now, but it is safer to implement some error handling.

Other command line arguments in this part of the code will be examined later in this chapter, when we start looking at validation. Characters found within the element are passed as an array of characters, along with the number of characters (length) and an offset into the array that points to the first character.
