Stripping empty elements while still conforming to DTD

Is there a simple way to strip empty elements from an XML while still 
conforming to the requirements of the DTD?  I know how to use the string() 
function to copy only those elements that contain data, but this often removes 
child elements required by the DTD.

Thanks for your help.
