Hi all,

I've done a bit of work on this and have modified the doit.groovy to:

import org.apache.tools.ant.Task

import java.lang.Class.*
import java.lang.reflect.*

def groovydoit()
{
  Task body = (Task) elements.get("sequential").get(0)
  println body.dump()

  Class c = Class.forName("org.apache.tools.ant.taskdefs.Sequential")
  def m = c.getDeclaredMethods()
  m.each() {
    println it
  }
  Field f = c.getDeclaredField("nestedTasks")
  f.setAccessible(true)
  Vector nestedTasks = (Vector)f.get(body)
  for (Enumeration e = nestedTasks.elements(); e.hasMoreElements();)
  {
    Task nestedTask = (Task)e.nextElement();
    nestedTask.perform()
  }
}

You'll notice that I'm using reflection to get the private field *nestedTasks *in *org.apache.tools.ant.taskdefs.Sequential*. After
that, I can do what execute() would do and I'm iterating over the element body.

I'm thinking that if I can do:

* Serialize each nested task to a string representation
* Make my tokenization substitutions
* Take the resultant string and form a Task from it

then, this would solve the tokenization challenge. Can anyone suggest how I can do the above?

Thanks,
