public class DatabaseXmlParseHandler
extends org.xml.sax.helpers.DefaultHandler

This class is used by the DatabaseXmlSerializer to read an XML-based database file from disk. It extends a DefaultHandler used by a SAX parser.

The class can read either an entire file into memory, or only parts of it -- excluding contents (headers only) or only selecting certain database version types (DEFAULT or PURGE).
