Hi Kumar,

The ObjectParamRule can't currently be invoked from xmlrules, nor can
the PathCallParamRule.

A patch for ObjectParamRule support in xmlrules has been submitted on
the development email list, but the Digester maintainers haven't yet
evaluated it.

So you could search the dev list for that email and compile the attached
code yourself. Or if you can wait 1-2 weeks, I think the odds are fairly
good that one of the maintainers will have committed the patch by then;
at that point you could use a nightly snapshot of Digester.

If xmlrules allows you to invoke FactoryCreateRule to create your class
instance, then you could implement a factory class which creates your
object and then passes the appropriate value for the "content" attribute
of your object.

Or you could change to using the digester API (rather than xmlrules)
until this is sorted out.

Regards,

Simon

Now, I have not been able to use either <set-properties-rule> or <call-method-rule> because none of them can pass the pattern name as parameters to the methods.
