Schema Validation over the network

[moon...@gmail.com]

I've got a question which I think should be easy, but I have not been
able to find any way to get it to work as of yet. What I would like
to do is to setup a webserver that has all of my schema documents.
Then I would like to be able to reference these schema documents on
the webserver from my xml documents. From what I've been able to get
working, it seems that the schemaLocation references the schema from a
local perspective.
Thanks,
Jeff

Hi Jeff,

No, there is no such limitation in the XML Schema specification. It may
be possible that you have no access to the resources on the server, for
instance if you are behind a proxy or behind a firewall.
Note also that you should be able to use also XML Catalogs to resolve
the references to the online version of the schemas to local copies of
those files - that is useful when working offline and when the
connection with the server is slow.

Best Regards,
George

I control the server and I can get to the schemas if I type them into
my browser, so I don't think that the problem is a proxy or firewall.
It gives me an error:

Error at file /home/jmoon/xmlServer/test.xml, line 4, char 87
Message: Schema in http://ws14.design.amis.com/test.xsd has a
different target namespace from the one specified in the instance
document http://ws14.design.amis.com/.

If you can help on this I can send you the schema I'm using and such
if that would help. I basically just want to get it working with a
really simple example.

<library
xmlns="http://ws14.design.amis.com"
xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"
xs:schemaLocation="http://ws14.design.amis.com/
http://ws14.design.amis.com/test.xsd">
</library>

Errors occurred, no output available

I'm using the xerces validator, if that adds anything to the
discussion.

Hi Jeff,

You have a namespace mismatch, see

<library
xmlns="http://ws14.design.amis.com"
xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"
xs:schemaLocation="http://ws14.design.amis.com/
http://ws14.design.amis.com/test.xsd">
</library>

You declare library element to be in the http://ws14.design.amis.com
namespace while when you associate the schema with the document you
use xs:schemaLocation="http://ws14.design.amis.com/
http://ws14.design.amis.com/test.xsd", note the trailing / at the end
of the namespace. Check the target namespace in your schema file and
make sure you use that both for the element declaration and inside the
schemaLocation attribute.

Best Regards,
George

Here's the current full setup. I'm still getting similar errors:
test.xml:

<library
xmlns="http://ws14.design.amis.com"
xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"
xs:schemaLocation="http://ws14.design.amis.com

http://ws14.design.amis.com/test.xsd">
</library>

test.xsd:
<?xml version="1.0"?>
<xsd:schema
xmlns="http://ws14.design.amis.com"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified"
version="1.0">
<xsd:element name="library" type="xsd:string"/>
</xsd:schema>

Output:
> DOMCount -s -n -v=always -f test.xml

Error at file /home/jmoon/xmlServer/test.xml, line 5, char 60
Message: Schema in http://ws14.design.amis.com/test.xsd has a

different target namespace from the one specified in the instance

document http://ws14.design.amis.com.

Error at file /home/jmoon/xmlServer/test.xml, line 5, char 60
Message: Unknown element 'library'

Errors occurred, no output available

Any more help would be appreciated. I'm sort of a newbie with xml validation.
Thanks!

The schema does not define a target namespace, you need

<xsd:schema
xmlns="http://ws14.design.amis.com"

targetNamespace="http://ws14.design.amis.com"

xmlns:xsd="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified"
version="1.0">

etc.

Best Regards,
George
