I have to process an XML file that contains (in part) the following structure <variables> <Variable> <ID>...</ID> <Name>...</Name> <Instance>...</Instance> <Value>...</Value> </Variable> </variables>
I have a predefined list of variables based upon their ID, an abstract Variable class, and then concrete subclasses of these for each valid ID. Variable contains a static method Variable getInstance(int ID) that creates a new variable subclass based upon the ID (the id-subclass mapping is based upon a properties file). The FactoryCreateRule allows for creation of classes based via a factory providing the identifiying parameter is an XML attribute. In this case it is not. It is a sub-element, I have no control over that. How can I use the FactoryCreateRule to call getInstance(int ID) in my Variable class when I need to extract the ID from a nested element not an attribute? Thanks Chris PS I did explore other options for the Variable class where there is just one class, but there is a need for polymorphism with regards to the variables that have led me to implement it this way, so changing Variable is also not an option. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
