take things to the next logical step, and look at reading XML.
Continuing with the example of converting a properties file to XML,
you are now probably wondering how to access the information in your
XML file. Luckily, there’s a solution for that, too! In this
section, for the sake of explaining how JDOM reads XML, I want to
introduce a new utility class,
class is essentially an XML-aware version of the Java
Properties class; in fact, it extends that class.
This class allows access to an XML document through the typical
property-access methods like
getProperty( ) and
properties( ); in other words, it allows
Java-style access (using the
Properties class) to
XML-style storage. In my opinion, this is the best combination you
To accomplish this task, you can start by creating an
XMLProperties class that extends the
java.util.Properties class. With this approach,
making things work becomes simply a matter of overriding the
save( ), and
store( ) methods. The first of these,
, reads in an XML document and loads the
properties within that document into the superclass object.
Don’t mistake this class for an all-purpose XML-to-properties converter; it only will read in XML that is in the format detailed earlier in this chapter. In other words, properties are elements with either textual or attribute values but not both; I’ll cover both approaches, but you’ll have to choose one or the other. Don’t try to take all ...
