RE: [xsl] error in XSL file when using JAXP

Hi Michael and David

I installed the latest version of the XSL Editor and
debugged my program as it started giving me the same
error as my JAXP.

I made the changes that both of you suggested and now
my program is working fine !

Thanks a lot for all your help.
