Beginning new method for building the xml_index table. This uses the
JDBC resultset directly rather than DBSaxNode, and recurses through the
records of the table. The new function 'buildIndex()' would be called, but
currently is not linked in to any code, so it shouldn't get in the way.
Checking in to checkpoint the code for the weekend.
