public class XMLFieldHandler

extends HierarchicalHandler

A SAX Event handler that takes over when a parent handler realizes that we have a field within a record. This handler then fills the field on the basis of the SAX events it receives. This handler only handles a single field stored as CDATA with no nested XML elements.
