  You can also have a look
at the EXPath ZIP facility.  It has
not been released yet, and is still in
development, but if you
generate (at least some of) the entries of the ZIP
file in XSLT,
it allows you to handle the creation of the ZIP file directly
from the stylesheet.  See a complete example at the end of this
message.

  As
I said, it has not been released yet, but you can find a dev
version at
http://www.expath.org/tmp/expath-zip-saxon-0.1.pkg.zip
for Saxon.  Just import
the included stylesheet in your own
stylesheet and put the JAR file into your
classpath.

  For any further info, see http://groups.google.com/group/expath
and http://www.expath.org/.
