Hussein -
Thanks to your help I now have XXE working using our no namespace XML
schema with styled views.
The key to the solution was:
[3] If your root element has no namespace, then you must modify the
<detect> rule in gpp.xxe.
For example, use this:
---
<detect>
<and>
<rootElementNamespace xsi:nil="true"/>
<rootElementLocalName>content_root</rootElementLocalName>
</and>
</detect>
---
Which means:
XXE! Apply the GPP configuration to the document you have opened if and
only if the root element of this document has "content_root", without a
namespace, as its name.
My poor attempts at obfuscation of the URL (i.e. hiding the names of our
servers) resulted in my creating more confusion and inconsistency in
describing the problem. Both the gpp.xxe and gpp.xml files did have
consistent namespaces however it was the no namespace issue that was
causing the problem.
Now that it is working as expected I will continue to evaluate XXE for our
environment. I have more work to do in creating a proper style sheet before
I can present this to the rest of my team.
Thanks you so much for your help and for educating me on XML namespaces.

Steve Deal

All your problems come from the fact that your gpp.xxe configuration
file and your gpp.xml file are inconsistent.
In gpp.xxe:
---
<detect>
<rootElementNamespace>http://myCompany.com/schemas/content/prod/gpp.xsd</rootElementNamespace>
</detect>
---
implies that your root element has a namespace:
http://myCompany.com/schemas/content/prod/gpp.xsd
(doesn't look like a namespace though!)
in gpp.xml:
---
<content_root xmlns="http://webdev.kodak.com/schemas/content/prod";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:noNamespaceSchemaLocation="
http://myCompany.com/schemas/content/prod/gpp.xsd";
xmlns:x0="http://www.w3.org/2001/XMLSchema";>
---
means
* that your root element has namespace which is
http://webdev.kodak.com/schemas/content/prod
(and which is not http://myCompany.com/schemas/content/prod/gpp.xsd!)
* and that XXE needs to use
http://myCompany.com/schemas/content/prod/gpp.xsd to validate elements
without a namespace found in gpp.xml (???).
Your problem is easy to fix by making everything consistent:
[1] I suspect that gpp.xsd has no targetNamespace (that's fine because
this will allow you to freely use Standard Edition).
[2] In such case, gpp.xml must start with:
---
<content_root
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:noNamespaceSchemaLocation="
http://myCompany.com/schemas/content/prod/gpp.xsd";
xmlns:x0="http://www.w3.org/2001/XMLSchema";>
---
That is, I removed: xmlns="http://webdev.kodak.com/schemas/content/prod";.
[3] If your root element has no namespace, then you must modify the
<detect> rule in gpp.xxe.
For example, use this:
---
<detect>
<and>
<rootElementNamespace xsi:nil="true"/>
<rootElementLocalName>content_root</rootElementLocalName>
</and>
</detect>
---
Which means:
XXE! Apply the GPP configuration to the document you have opened if and
only if the root element of this document has "content_root", without a
namespace, as its name.
Please find modified gpp.xxe attached to this email.

I think this alert dialog box will disappear once you'll fix your
configuration (if gpp.xsd really has no targetNamespace).

I'll answer these questions as soon as your initial problem is solved.
