Re: [xsl] how to make a progress report in XSLT? (was "how to make a log file in XSLT?"

Hi,

How about running these transforms from a shell script that renames the
output file after the transform, so that for the transform, file logA is
read and file logB is written out. Then on exit, the shell script removes
logA and renames logB to logA?
