RE: Accepting any URL on the default namespace declaration

Radu,

 

No – that’s not the idea.  

 

All I was trying to do was use a simple piece of well-formed XML without any namespace prefixes in it!!!

 

This appears to be one of those situations where the Java implementation stack (Saxon, ‘Beans, et al) default behaviour is not 100% aligned with the W3C specifications.

 

First off XMLBeans complained about the well-formed XML unless there was a default namespace declaration – even though technically – one should not be needed (there’s no namespace prefixes used).

 

Upon deeper inspection I found that this was being triggered by what was defined in the schema used to do the XMLBeans generation.

 

It appears that XMLBeans locks the default namespace declaration into what it generates to be explicitly that URL from the schema.

 

Again this is not 100% kosher – since the well-formed XML should be allowed to define the namespace without the URL for the declaration having any special significance.

 

I can understand WHY the XMLBeans is doing this – its using it as an unofficial “version” marker – but I’m asking if there is a way to turn this behaviour off?

 

Reason is that I fully expect people that start working with our well-formed XML to want to REPLACE the URL in that default namespace declaration with their own URL – not ours.  And technically by the W3C – they should be able to.

 

Thanks, DW

Let me see if I got this straight. You want that regardless of the namespace in the document, XmlBeans to consider it as having no namespace at all. If this is correct, I have to say I find it pretty strange. You can do two things:

 

1. Try using .setLoadUseXMLReader() and pass in a Reader that doesn't use namespaces

2. Write a SAX filter that strips the namespace before passing the events to XMLBeans; this is not as difficult as it may sound.

 

I suppose that we could always add an option for XMLBeans to do this automatically; but first, is this a good characterization of what you had in mind?

Subject: Accepting any URL on the default namespace declaration

Just trying to puzzle out the XmlOptions for the Factory.parse – the FAQ and the Javadoc gives some parameters – but no guide to their usage / purpose.  Not always clear from the name of the parameter.

 

What I’m attempting to do is to have the namespace declaration URL be ##any – instead of enforced to be a specific URL value.

 

E.g.

 

<myxml xmlns=”foobar.com/mustbe/this/that”>

  <test/>

</myxml>

 

Where the namespace URL is forced to match the value put in targetNamesSpace in the XSD that was used to generate the XMLBeans.

 

I want to relax that check and allow any URL to be used for the default namespace.

 

Thanks,

 

David Webber
