To solve your problem, i'd suggest a scripted approach using something
like the <groovy> or <scriptdef> task. If using groovy for example, this
would allow you to use similar Java code as in your suggestion and give
you much more fine grained control over error handling etc e.g. if the
data in the file is malformed for some reason or the file is missing.

Thanks

Adam
