| <section name="The Digester Component"> |
| |
| <p>Many Jakarta projects read XML configuration files to provide initialization |
| of various Java objects within the system. There are several ways of doing |
| this, and the <em>Digester</em> component was designed to provide a common |
| implementation that can be used in many different projects.</p> |
| |
| <p>Basically, the <em>Digester</em> package lets you configure an XML -> |
| Java object mapping module, which triggers certain actions called |
| <em>rules</em> whenever a particular pattern of nested XML elements is |
| recognized. A rich set of predefined <em>rules</em> is available for your |
| use, or you can also create your own. Advanced features of <em>Digester</em> |
| include:</p> |
| <ul> |
| <li>Ability to plug in your own pattern matching engine, if the standard one |
| is not sufficient for your requirements.</li> |
| <li>Optional namespace-aware processing, so that you can define rules that |
| are relevant only to a particular XML namespace.</li> |
| <li>Encapsulation of <em>Rules</em> into <em>RuleSets</em> that can be |
| easily and conveniently reused in more than one application that requires |
| the same type of processing.</li> |
| </ul> |
