File:SaxReader
Purpose:Wrapper OpenEdge/Core/XML/SaxReaderfacade.p which handles SAX
parser events.
Author(s):pjudge
Created:Tue Jul 13 09:50:23 EDT 2010
Notes:* The strongly-typed events in this class correspond to the
SAX-READER events, as documented in the ABL documentation
set. This class basically acts as a wrapper around a .P
since classes can't be specified as listeners for the SAX-
READER object. This class then re-publishes the events as
strongly typed events.
and not the sender,eventargs convention otherwise used in
this reference code.
