Looping over lines in a file

[Mike Castle <da...@ix.netcom.com>]

I have an input file I need to process with an ant task.


line1
line2
line3


I need to process each line individually.  That is, massage the line, do
some other internal processing on it, and start a java process with that as
an option.

What is the ant way of doing this?

I've started out with <loadfile/> and <foreach/>, but can't figure out how
to either easily turn EOL into a `,' (portably I might add) or tell foreach
that a newline character is the delimiter.

And apparently I haven't found the good search terms to find anything in
the archives.

Suggestions appreciated,
mrc

Wasn't sure how to get the delimite to be EOL character, until I did more
playing around.  Found ${line.separator}, which does appear to work as the
delmiter.

Thanks for kick in the right direction.

Also, foreach has a "delimiter" attribute.  Don't know
whether this would have worked, but I can't see why it
shouldn't.

To answer my own questions:

filterchain, prefix, striplinebreaks

Just had to step away from the keyboard for a few minutes.
