Hi Begue,
I don't understand what you are asking.
How about changing the value of an xlink:href on an image element
to load a different set of data?

Hi Begue,
You can't just create a ScriptingEnvironment. One is created
as part of the build of the document (if appropriate). Unfortunately
we currently don't provide real access to the Window Object from
Java. Fortunately you can fairly easily implement all the window
object functions yourself in Java - if in no other way than by
copying the implementation that Batik provides in the
BaseScriptingEvironment.Window inner class (although often you
can do a better job by just using the JDK classes).
