You are right Steve, that was an error on my part.

Subject: Re: Checking if a Target Exists
Hi Vimil,
Thanks for the code! I'm pretty sure the fifth line of the script should be:
var targetname = attributes.get("targetname");
I haven't tried running it yet today, but I will test it and let you know how
it works.

The conditions <http://ant.apache.org/manual/Tasks/conditions.html> page tells
us: "Types include tasks, datatypes, scriptdefs,
macrodefs and presetdefs." So, I'm not sure if target is a task. I'll check
it out.
Thanks to all!
