Hello,
I’ve used the ArcGIS Pro SDK ‘Metadata Toolkit’ and user guide on GitHub to successfully create a custom metadata editor page (similar to the screenshot below), however, there doesn’t seem to be any documentation on how to actually display this information when you save and close the editor. The guide on GitHub mentions XLST stylesheets but there are no steps to follow or code samples to show how this is achieved.
Any help or assistance would be very much appreciated.
