How do I loop in Ant?

I have a <property name='xxx' value='yyy'/> where I have a set of
targets to perform for value 'yyy'. But I want to have an array of
'yyy' values, i.e. to perform the same set of commands for different
values of the property or loop through values.

Thanks.

Ant doesn't really support this. You can declare a macro so that you can
perform the same tasks for different inputs.

http://ant.apache.org/manual/CoreTasks/macrodef.html

Alternatively, you can download the Ant contrib tasks. These include a
foreach task.

http://ant-contrib.sourceforge.net/tasks/tasks/index.html

You don't. In an attempt to force declarative coding style over
procedural, Ant is deliberately (if not perhaps correctly) light on
control structures to do this.

If your set if file-related, then you might be apply to use Apply (Ant
1.7+)

Otherwise there's a foreach task from ant-contrib, but this limits
easy deployment of your Ant buildfile to other Ant installations that
might not have this task installed.
