I would like to use deeply buried nodes of xml tree as nodes (and connections) in a diagram. How do I specify the properties holding them?
In the examples of the samples plugin the nodes are children of the root node so that they can be easily specified.
The with construct is only applicable for forms. If the model needed for the diagram is buried within a larger model, you can navigate to the relevant root element when instantiating SapphireDiagramEditor in the editor class.
