All Implemented Interfaces:

org.exolab.castor.xml.EventProducer

public class AttributeExpander

extends java.lang.Object

implements org.exolab.castor.xml.EventProducer

This class expands attributes in XML documents as the document is being parsed. It is designed to be used in conjunction with the Castor unmarshalling framework.

To be expanded, attribute values must contain text of the form ${property.name}, where property.name is a property returned by System.getProperty().
If no property exists, the attribute value remains unchanged.
