Split XML file into seperate files with XSLT and ANT

Hello,

I don't know if there is a standard way to do this, but maybe you have
an idea.

I have many XML files which hold multiple XML fragments of a specific
type <contentitem>..</contentitem> For an easy import of those seperate
contentitems into a CMS it would be better to split those fragments up
into different file (one contentitem per file).

As I am doing this inside an ant pipeline, I wonder if there is an
elegant way to do this with a mixture of XSLT and other file tasks?

Can you help,

Robert
