RE: Calling java from xsl - with xml as parameter

Calling extension functions from XSLT depends on the XSLT processor you are
using, so we can't answer without that information.

You haven't said what the Java method signature is. It sounds to me as if
the Java method is expecting a string, and so the call is taking the string
value of the supplied node, just as it would when you call an XPath function
that expects a string. But you actually seem to want the Java method to get
the XML serialization of the node - you won't get that automatically, you
will have to call a function such as saxon:serialize() to get it.

What is your Java method actually doing?

Well, yes, you can't have XSLT instructions in the middle of an XPath
expression (or XML elements in the middle of an XML attribute). The fact
that you're making this mistake suggests we ought to start from first
principles and look at the problem you are trying to solve and whether your
whole approach makes sense.
