Hi,
Can u please tell me how i can user SAXON parser? I am using FOP for
processing XML data using XSL:FO for outputs. It fails after just 10mb. i
have to process larger volume of data say 100mb. I can see in the FOP.bat
file that its using XALAN and SAX Parser. Please guide me.

Make a backup copy, remove xerces.jar, xml-apis.jar and xalan.jar
from the classpath, put the saxon.jar into the classpath and
make sure you are not using JDK1.4.
A somewhat simpler approach is to use the command line utility
from Saxon to produce a FO file from your XML and XSL, then run
this file through FOP.
