I do not know if this is the right sub-forum, by the way.
I explain my situation: through XPath Expression (define in an external XML file which I read using JAXB) I read data from a second XML file (a datasource, for example).
Then, inside my Java code, according to which Node name (org.w3c.node), or Nodelist, or attribute name, or something else have been selected from the datasource I make some operations on them an display them on the screen.
As you can understand, inside the Java code there are direct references to the names of the Node, attributes and so on from the datasource.
What I would like to do is to remove these "hard coded" part from the Java code and allow make the processing using another external file (XML, XSLT, or what else).
This means that anyone using my software can define its own data processing defined externally from the Java source code on its data source XML file without changing the Java source code.
