RE: Namespace prefix throws spanner in works
A question about xmlbeans: if I change the schema locally and compile my xmlbeans into a jar, is that elementFormDefault attribute ( all schema info) compiled into my jar, or will xmlbeans validate() try to reference the schema again? In my current set-up in Eclipse, I am certain that the app is not accessing the schemas once running.

I guess that you've declared the mediumName element as a local element in the schema (this will happen if it is not an immediate child of the top-level schema element). How you refer to local elements and specifically whether you should include a namespace prefix or not is controlled by the form attribute on the element's declaration in the schema. If the form attribute is missing then it's controlled by the elementFormDefault attribute on the surrounding schema element. The default in both these cases (and therefore what will happen if they are both missing) is unqualified. This means that local elements _must_ be referred to without a namespace. I'm guessing that this is what has happened in your case. If the form value is unqualified then it is an error to refer to the local element using a namespace prefix and the validator correctly points this out. It sounds like you have control over the schema. If so then you can change it so that either that specific element declaration has form=qualified or you can set the same rule for the whole schema by setting elementFormDefault=qualified in the schema element instead. Note that it is equally an error for you to be expecting a namespace and not to see one - so if you update your schema in this way be sure that all clients know about it and will ensure that all local elements are namespace qualified in all the instance documents. http://www.bbc.co.uk/ This e-mail (and any attachments) is confidential and may contain personal views which are not the views of the BBC unless specifically stated.

RE: Namespace prefix throws spanner in works
Hi Adam Re your question on which elementFormDefault applies (1) or (2) - unfortunately for you it's the one in the schema element surrounding the local declaration of mediumName in the scheduleNameGroup model group definition. So the unqualified treatment required by (2) is correct. I have some sympathy with your other comments as I prefer the elementFormDefault=qualified setup myself. But having said that, elementFormDefault=unqualified is not illegal. And it's not as if the attribute has been forgotten (and therefore defaulted); rather the schema designers have explicitly chosen to make it unqualified. It is the responsibility of whoever constructs the instance document to conform to the schema so, technically, whoever is providing you with your instance doc is providing invalid XML which should be rejected and you should contact them to fix it. But if you're happy having your local copy of the schema then so be it.

Does this make no difference? As far as my project is concerned, I can keep a local copy of the schema and change that elementFormDefault. That will sort out my xml beans validation. Truth be told this is actually the second change we have to make to the schema, which points a finger at the WorldDAB committee who wrote it. I did email them when I had to make the first change but received no reply. Oh well.

My xml header looks like this: ?xml version=1.0 encoding=UTF-8? epg xmlns:epg=http://www.worlddab.org/schemas/epg; xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance; xsi:schemaLocation=http://www.worlddab.org/schemas/epg epgSchedule_11.xsd system=DAB Etc etc And the xml where the first error occurs looks like this: programme shortId=59033 epg:mediumNamePM/epg:mediumName [snip...] /programme And the error says: Expected element mediumName at the end of the content in element programme If I remove the epg: namespace prefix from the elements, then it validates fine, but I can't do that in the live environment - the app
RE: Namespace prefix throws spanner in works
Hi Adam scomp has an option, -dl, which will download included and imported schemas from the network. In the absence of this option no network downloads take place and it searches for includes and imports locally. I'm not sure of the details of exactly how this works but if you are compiling successfully without the -dl option then it is correctly finding the imported schema from somewhere local. All the details of the infoset, including the information about the namespace against which to validate instance docs, are included in the .xsb files which are part of what gets generated in the jar. So when you run validate() on an XmlBean you are comparing the instance to the information in the .xsb's which in your case were compiled from the local schema.
