How to validate XML files without specifying xmlns namespace attribute in the root element? [message #675080]

We have a lot of projects that consists of XML files. We have to validate all these XML files based on a single XML schema.

In order to realize this, we have used XML Catalog entries to associate an XML Schema with a given namespace key. In this way you define the location of XML Schema only once in XML Catalog and all XML files will be validated based on this single XML Schema. You can see the XML Category Entry below:

Entry element: URI
Location: dm_d/src/DESchema.xsd
URI: platform:/resource/dm_d/src/DESchema.xsd
Key type: Namespace name
Key: http://www.example.com

This method works fine, BUT only thing that you have to do is to add 'xmlns' namespace attribute to root element of every single XML file in your projects.

We don't want to add the namespace attribute to each XML file, because we have to update a lot of Client projects, which is not efficient and feasible.

At the moment, we are looking for other ways of XML validation based on a single XML schema without introducing xmlns namespace to each XML file.

How can we do this in Eclipse IDE?

Normal XML Validation (e.g.: underlines when you have wrong closing tag,..) in Eclipse XML editor works without namespace. Here, you don't have to define anything that relates to XML Schema. How it is done for this normal XML validation?

Can we do the same as in the normal XML validation?

Any tips, guidance in this direction are very appreciated.

Thanks! Smile

Does your schema have a target namespace? If so, your root element must
be using that namespace to conform to it, rigth?

I don't think so. I've asked about 4 years ago about similar (if
not the same) thing:

"Infer an XML Schema or DTD grammar depending on the root element
name" <http://www.eclipse.org/forums/index.php/mv/msg/63174/>

I haven't seen development on the front, at least not in the base
Eclipse bundles.

Yes, my schema has a target namespace, namely http://www.example.com (as described above). When I add this namespace to my XML file, it works fine, it validates.

BUT the problem is that I don't want to add namespace to root element. Because it is not feasible to update all XML files/projects that are already in the client/customer side.

Do you know how to validate XML file based on XML Schema without introducing namespaces?

It is somehow done, in normal XML editor, it underlines with red color when you have non-valid XML. Where is that Schema? It/namespace is NOT in the ROOT element.

How can we do that?

Yes because for an instance to conform to a schema it must use the
namespace of the schema on the root element.

Then you should be using a schema without a namespace.

A root element without a namespace is describe by a schema without a
targetNamespace.

It might be hard to have multiple schemas without a target namespace
(see other comment in this thread) but hopefully there's at least
support for one schema without a target namespace.

Bug 206370 is a relevant read, but the short answer is no, not without
writing plug-ins to deal with your special case, and maybe not even
then. They're not *.xml files at least, right?

How an we do that?

There was an extension point added by https://bugs.eclipse.org/341279 that allows one to associate schemas without requiring explicit reference of the schema in the XML document. If you're willing to implement it, this might help you.

They are 'XML' files with javascript embedded in some xml tags with <![CDATA[ .. ]]>.
But the structure of all XML files confirms all XML rules(properly nested tags, closing tags...). JS code is always inside <![CDATA[ .. ]]>. SO, they are valid XML files.

I actually meant in terms of their file names. You have considerably
more flexibility if your file names can be used to differentiate them.
