Macrodef and If

[Steve Amerige]

I'd like to do something like:

   <if>
   <mymacrodef/>
   <then>
        ...
   </then>
   </if>
   <macrodef name="mymacrodef">
   ...
   </macrodef>


Within the macrodef, there would be places it would return true and other places it returns false.  I want the solution to be wholly 
in Ant (no Java, Groovy, external file use, etc.).

Is it possible?  If so, can you show an example of how the mymacrodef would be 
coded?

Thanks!
