Hola @abe.sherman
Let me understand your request… do you want to show or handle on your APP the XML data generated by your NVR?
If so, I think it’s possible. Due to XML is the JSON’s father I think what you try to do can be done by using an API.
I found this quickly that looks easy to use: GitHub - factmaven/xml-to-json: Simple API that converts dynamic XML feeds to JSON through a URL or pasting the raw XML data. Made 100% in PHP.
Its syntax is:
Of course, you must use some Glide’s API plugin later to handle JSON payload received from XML API and organize that data in your tables/sheets.
I hope it helps.
