How validate Schema with JAXP DOM?

Posted: Mar 10, 2003 3:38 PM

I want to use the Java XML API so that I can pop in and out different
implementations of XML parsers as I need/want to. However, as far as I can
tell, if I want Xerces to validate an XML document with a Schema, I CANNOT
use the DocumentBuilderFactory method. Is this correct?

As far as I can tell, the only way to make it use a schema for validation
is by setting certain parser features such
as "http://apache.org/xml/features/validation/schema" and this can only be
done on either a SAX Parser or Xerces' DOMParser, which you MUST refer to
explicitly by name to use "setFeature" since setFeature is not part of the
DOM interface.

Does anyone know if there's a way around this? Can I actually use the
following and make it use an XML Schema for validation?

<code>
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setValidating( true );factory.setNamespaceAware( true );
DocumentBuilder builder = factory.newDocumentBuilder();
Document doc = builder.parse( file );
</code>

If not, then what was the purpose of the above interface (JAXP)?!
