Processing XML - Java - page 794

Discussion

The Serialization demonstration in Saving and Restoring Java Objects showed an abstract
base class that called upon abstract methods to write the file out in some format.
Example 20-3 is the XML subclass for it. If you haven't read that section, all that matters is
that write() is called with one argument, the tree of objects to be saved.

Example 20-3. SerialDemoXML.java
public public class class SerialDemoXML SerialDemoXML extends extends SerialDemoAbstractBase {

public public static static final final String FILENAME = "serial.xml" ;

public public static static void void main ( String [] args ) throws throws IOException {

new new SerialDemoXML (). save ();

new new SerialDemoXML (). dump ();

}

/** Save the data to disk. */
public public void void write ( Object theGraph ) throws throws IOException {

XMLEncoder os = new new XMLEncoder (

new FileOutputStream ( FILENAME ));
os . writeObject ( theGraph );
os . close ();

new

}

/** Display the data */
public

public void throws IOException {

XMLDecoder inp = new

void dump () throws

new XMLDecoder (

new FileInputStream ( FILENAME ));
System . out . println ( inp . readObject ());
inp . close ();

new

}

}

Transforming XML with XSLT

Problem

You need to make significant changes to the output format.
