Hi
I am using the XercesDOMParser to validate (against an xsd schema) XML
documents that *should not* contain namespace or schema location
information. I do this (successfully) by using the parser's
'setExternalNoNamespaceSchemaLocation()' function.
My next goal is to prevent those same documents from ever specifying schema
locations or namespaces so that my validation cannot be tricked - ie. I want
to only ever validate these documents against my schema, and any other
schema references should be ignored. I thought this would be possible by
instantiating my parser like:
XMLGrammarPool* grammarPool = new
XMLGrammarPoolImpl(XMLPlatformUtils::fgMemoryManager);
XercesDOMParser* parser = new XercesDOMParser(NULL,
XMLPlatformUtils::fgMemoryManager, grammarPool);
... and then using:
grammarPool->lockPool();
grammarPool->unlockPool();
grammarPool->clear();
parser->loadGrammar(
schemaLocation
Grammar::SchemaGrammarType,
true
);
... to control what schema grammars the parser knows about.
However this does not appear to work. When I attempt to parse and validate
the following document (which does not conform to one of my schemas) I do
not get any validation errors!
<xt:test
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:xt="extra"
xsi:schemaLocation="extra ~~extraSchemaPath~~"
>
This
should
<c>fail!</c>
</xt:test>
Is there something obvious that I am doing wrong?

Nathan
p.s. I would be happy to post a little more of my code if necessary.
