question about validation feature in xerces 2.7.1
Hello Xerces gurus,
I am trying to enable the feature
http://apache.org/xml/features/validation/warn-on-undeclared-elemdef
using xerces 2.7.1, which I just downloaded from
http://www.wmwweb.com/apache/xml/xerces-j/.
This is my java class:
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;
import org.xml.sax.SAXNotRecognizedException;
public class TestSAXParser
{
//~ Methods
----------------------------------------------------------------
public static void main( String[] args )
{
try
{
SAXParserFactory factory = SAXParserFactory.newInstance( );
factory.setFeature( VALIDATE_XML_FEATURE, true );
factory.setFeature( WARN_ON_UNDECLARED_ELEMENT, true );
factory.setFeature( WARN_ON_DUPICATE_ENTITY, true );
SAXParser parser = factory.newSAXParser();
}
catch ( SAXNotRecognizedException snre )
{
System.out.println( "feature not supported: " +
snre.getMessage() );
snre.printStackTrace();
}
catch ( Exception other )
{
other.printStackTrace();
}
}
//~ Static variables
-------------------------------------------------------
private static final String VALIDATE_XML_FEATURE =
"http://xml.org/sax/features/validation";
private static final String WARN_ON_UNDECLARED_ELEMENT =
"http://apache.org/xml/features/validation/warn-on-undeclared-elemdef";
private static final String WARN_ON_DUPICATE_ENTITY =
"http://apache.org/xml/features/warn-on-duplicate-entitydef";
}
When I run the code, however, I get this error:
C:\Documents and Settings\mhannaford\Desktop\test>java -classpath .
TestSAXParser
feature not supported: Feature
'http://apache.org/xml/features/validation/warn-on-undeclared-elemdef'
is not recognized.
org.xml.sax.SAXNotRecognizedException: Feature

Is there something obvious I am doing wrong, or is the feature not
enabled in this version of Xerces?
Thanks for your help.

Re: question about validation feature in xerces 2.7.1

Hello Michael,
It's a long standing bug [1] and has been broken for so long I'm not sure
any version of Xerces 2.x ever supported the feature. It's been on my TODO
list for awhile and I'm hoping to finally get around to it for Xerces
2.8.0.
By the way you weren't actually using Xerces 2.7.1 when you ran your test
(probably since you didn't put the Xerces jars on the classpath). The
com.sun.org.apache.xerces.internal.* packages originate from Sun's Java
5.0.
Thanks.
