Substring / regex on a package name?

[Ben Gill]

Hi,

 

I have two questions:

 

1) I have a property called "com.myapp" within my build.xml file (or at
least loaded in at runtime), and I want to strip off everything past the
first dot (to get the base package name com)...

 

Is that possible?

 

2) Is there a rename packages ANT task?

 

Thanks
