Error Importing XML using SSIS XML Source maxOccurs=1 on element-CodePudding

When attempting to import XML data using an SSIS package, I keep getting this error :

The XML Source was unable to process the XML data. The Xml source document contains multiple "CaseCode" elements and maxOccurs=1 was specified in the Xml schema.

I'm using the following sample data:

I'm using the following XSD: PasteBin

As far as I can tell there are no multiple CaseCodes inside a Case. I'm confused, don't work with XML much, any help or pointers are much appriciated.

CodePudding user response：

I tried to validate the XML against the XSD.

The validation revealed few errors.

You need to make a decision about what is correct XML or XSD.
