How to read content of a file ?

hi,
I have a build.xml file that does a lot of things and then in the end there is a .zip file generated.
In a .txt file there are a set of file-names reprenting the names of the .zip files to be generated.
I would like to make a loop so that the build.xml file is called as many times as there are filenames in the .txt file (passing the name to the build file).
I could do this with a batch file (under DOS) that reads the .txt file and then calls the build.xml file.
Is there a possibility I could do this entirely with Ant (maybe 2 ant files - one is reading the filenames and the passing this to the second ant file using <ant> ?)
Any ideas ?
Regards,
Stefan

You might try the <foreach> task from ant-contrib, http://ant-contrib.sourceforge.net/

Hi,
sorry to come back only now but I'm afraid my problem has not been solved.
Can anyone give me an example of how to read the content of a file with <foreach> ant task ?
The file content just contain the names of the files create (one filename per line) :
filename1
filename2
filename3
..

Thanks
Stefan
