public class XMLTransactionHandler

extends HierarchicalHandler

A SAX Event handler that takes over when a parent handler realizes that we have a transaction element. This handler then fills in a record's fields on the basis of the SAX events it receives. TODO: Give it the ability to handle compound nested transactions. (Not so hard, really. :-)
