Re: [jboss-as7-dev] Validation of XML Parsers / Schemas
Can this be done without *requiring* changes to subsystems?
ExtensionParsingContext.setSubsystemXmlMapping(String namespaceUri,
XMLElementReader<List<ModelNode>> reader) is a stable API that we cannot
break.
A new method could be added to register a parser that requires a
ValidatingXmlReader to be passed in, but we can't force subsystems to
change their impl's
public void readElement(final XMLExtendedStreamReader reader, final
List<ModelNode> list) throws XMLStreamException
to
public void readElement(final ValidatingXmlReader reader, final
List<ModelNode> list) throws XMLStreamException

The topic of how to validate the XML parsers or the schemas crops up
every now and again.
I have been having a couple of ideas of how we could at some point look
into this: -
http://community.jboss.org/docs/DOC-17243
The proposed idea actually covers two parts: -
- A wrapper around the existing API that allows the parsers to just
request the elements / attributes they require and leave the wrapper to
handle all the error handling we currently have distributed across the
parsers.
- This then allows us during testing to validate that the calls match
the structure defined in the schema.
I may try prototyping something other the weekend but thought I would
put this out there and see if anyone has any thoughts / comments.
