Sounds like you need an external tool for this. If you can depend on unix tools, you can use the paste command (see man paste) and run it from ant using the exec task. If not, you can either

• write the tool in java, then use tasks javac and java to compile and run it from ant
• or use the script task to embed the tool in your ant script using some scripting language
