Hi Mitch, thanks for the code. Currently, I've got a different solution running but it's always good to have examples.

It is better to subclass the XPathEntityProcessor and put it in a state that prevents it from calling "initQuery" which triggers the dataSource.getData() call. I have overridden the initContext() method setting a go/no go flag that I am using in the overridden nextRow() to find out whether to delegate to the superclass or not. This way I can also avoid the code that fills the tmp field with an empty value if there is no value to query on. Cheers, Chantal
