Revision:	1.3
Committed:	Fri Nov 17 14:45:56 2000 UTC (24 years ago) by pjm2
Branch:	MAIN
Changes since 1.2:	+5 -2 lines
Log Message:	Fixed a major parsing problem by wrapping the XML in an InputSource object and removing null characters from the input. Also modified the XMLSender class so that it no longer sent "null" when the last line of an input file is reached.
