if 0 { schlenk I have made up this small toy for a collegue who needed to use Saxon 7.x for some transformations and he was bored at using the cmdline. So i did this one and added basic support for tDOM and TclXSLT also.
Many thanks to Rolf Ade for pointing out some really broken stuff in the original version.

# A little multi XSLT processor demo in Tcl/Tk
#
# This script is a simple demonstration how to use the following XSLT Processors
# from Tcl/Tk to transform XML files via XSLT.
#
# It is written for use with tclkit or ActiveStates distro.
# You have to set your auto_path before sourcing it, so
# it can find tDOM or TclXSLT packages.
#
# The following processors can be used:
# InstantSaxon 6.5.2 (Windows only) (http://saxon.sourceforge.net/)
# Saxon 7.x (with java available) (http://saxon.sourceforge.net/)
# tDOM (http://www.tdom.org)
# TclXSLT (http://tclxml.sourceforge.net/tclxslt.html)

showWindowLES on July 23 2004, 358 days after this page's last edit: this is a great little app. But it's sad that no one seems to be using it, because there is a tiny silly bug that prevents it from running at all: Inputfile:\t$inputn , in line 315, actually should be Inputfile:\t$input\n .
schlenk your right, fixed it but why didn't you fix the code in place? Its a wiki after all. :-)
