Generating an XML model from an Object-Oriented Model

You can only generate an XML model from the active OOM diagram window.

To update an existing XML model by generating from an OOM:

1Select Tools→Generate XML Model to display the XML Model Generation Options dialog box.

If you do not have an XML model in the current workspace, the Update existing XML Model option is not available.

2Select the Update existing XML Model radio button.

3Select a model from the Select model dropdown listbox, if the current model has already been generated.

or

Click the Ellipsis button, beside the Select model dropdown listbox, and select an existing model in the Select a model dialog box.

Preserve modifications

Select the Preserve modifications check box if you want to preserve objects in the XML model.

If you clear this check box, all existing objects in the XML model will be removed from the model, leaving only the objects generated from the OOM.
