Hello, ad 1:
Vadim, as you suggested it finally works with this expression - thanks!: <util:include-expr><util:expr><xsp:expr>mm.marshal(mm.getSimpleItems())</xsp:expr></util:expr></util:include-expr> ad 2: The contentHandler used in 2 b) is a TraxTransformer instance. Is it possible that in this case the resulting intermediate XML contains the '<?xml version="1.0" encoding="UTF-8"?>' expression before the actual marshalled xml? Could this be the reason for the javax.xml.transform.TransformerException: java.lang.NullPointerException? So far I did not cope it to apply a stylesheet correctly to the marshalled xml. The stylesheet works correctly for option 1: Regards, Harald > > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] > > > > > > 1.
