Hi Ninju,
I really really want to thank you for that great help. I almost spent 7
hours and was still trying to figure it out when your reply came.I tried
everything from <antcontrib> to <replace> to <propertyset> and god knows
what else....

And you made it sound soo easy...wow..you are genius man.

Thanks again for that great help...really appreciate it!!!!!
