Adding a new unique key to a schema.

Post by babynapoleon » Sun May 13, 2018 2:35 am

Hello,

I have a load of large XML files that I need to process into a database on a continual basis. The XML schema is not great as I can't use the "key" to link the data together because it doesnt extend through the elements. I have tried to add a unique identifier to the schema with Oxygen and I can't :(

The "Keys" element is not linked through the schema so the data doesnt relate properly in a database; please can you give me a hand figuring out what to do with this schema as it is causing me big problems :(

Thank you so much for helping and for your advice.

Here is the schema:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
