Re: writing error file

"2>error.log" should work. If not, it's really an operating system question
rather than a Saxon or XSLT problem, but I guess we can help if you tell us
exactly what OS environment you are in and what command shell you are using.

set errorfilename=C:\errors\%date:~-4%%date:~-7,2%%date:~-10,2%.log
set saxdir=C:\Programme\saxonb8
set filedir=C:\XMLBatchProcessor\input
java -jar %saxdir%\saxon8.jar -o %3 %3 first.xsl >> %errorfilename%
..
.. (calling further xslts)
..
..

appreciating your help,
hoping my information is enough detailled
