It is possible, either with or without the split. Here is a solution
without the split, which makes use of ant-contrib (yes, I just cannot
work without it, it's too powerful to be ignored imho). Of course,
you'll have to adapt it to what your script expects as an argument,
whether the build should fail if the script fails, etc (and note that
ant-contrib also has try/catch).

Note that while <dirname> looks great, it has a huge drawback: its
output is a property, and properties are immutable. At least, they're
immutable with ant 1.6.x, I don't know for ant 1.7.x.
