Hi,
this line
<param name="weekly-end-date" expression="${weekly.end.date}"/>
means that ant will pass to the stylesheet literally ${weekly.end.date}
if weekly.end.date is not set.
what you would need and which does not exist would be something looking
like that :
<param name="weekly-end-date" expression="${weekly.end.date}"
if="weekly.end.date"/>
meaning pass the weekly-end-date parameter to XSL if the property
weekly.end.date is set.
Miracle, this construct exists, and even better in Ant 1.6.5.
Regards,
Antoine
