Hello everyone, I´ve been working several days in this and I can´t get the right way to solve it. Let´s take this example XML. <ReadingList> <Reading> <idReading>123</idReading> <value>66.0</value> <endValue>34.0</endValue> <initialValue>12.0</initialRValue> </Reading> <Reading> <idReading>123</idReading> <value>66.0</value> <endValue>34.0</endValue> <initialValue>12.0</initialRValue> </Reading> <ReadingList> I don't have any problems to list every Reading in mi jasper report, I just use XPath and point the Reading node as queryString. The problem is when I need to do some operations and more logic operations over the Readings and show the data when is already processed, thought one way could be send as a list the ReadingList node to my own Scriptlet class and do everything there, but I'm not getting the correct way to do it. Please, I'd really aprecciate if someone could help me with it.
