Validate XML against XSD generated by Oxygen

[Fiona Chen]

Hello:

I use Oxygen to generate XSD. However, Oxygen hinted Error:

Code: Select all

The {target namespace} of an attribute declaration must not match 'http://www.w3.org/2001/XMLSchema-instance'.

This predicament causes me to comment out below:

Code: Select all

  <xs:import namespace="http://www.w3.org/2001/XMLSchema-instance" schemaLocation="xsi.xsd"/>

If I comment out the subsequent referenced schema in the orignial XML:

Code: Select all

 <xs:attribute ref="xsi:schemaLocation" use="required"/>

Code: Select all

  <xs:attribute ref="xsi:type" use="required"/>

My Java API will fail the XSD validation, as the original XML referenced the import ns:

Code: Select all

 <value nullFlavor="OTH" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:type="CD">

The Java API validation throws error:

Code: Select all

 cvc-elt.4.2: Cannot resolve 'CD' to a type definition for element 'value'.

I review below post but as the "CD" uses

Code: Select all

xmlns:xsi

, it wouldn't work.

Do you have a realistic solution for this problem?

Hello,

We are using Trang to generate an XSD schema from XML files. It seems that Trang generates an xsi.xsd schema when you use attributes from "http://www.w3.org/2001/XMLSchema-instance" namespace. There is already an issue for this on the Trang project:
https://github.com/relaxng/jing-trang/issues/132

As an workaround you can remove the "xsi.xsd" schema import from your generated XSD schema. You need to delete the following line:

Code: Select all

<xs:import namespace="http://www.w3.org/2001/XMLSchema-instance" schemaLocation="xsi.xsd"/>
