What are the options to run a target for each file in e.g. a fileset?

There is clear one solutions: write your own task. But I'd like to have the build.xml independent of any Java code. So I see potential areas:


- existing core/optional task (didn't find any).


- script. Javascript? How to access result of fileset?


- third party task (almost same as developing my own - just saves some time).


- my own task in Java.
