Why can I get the validation to work??

[Johan 'Spocke' Sörlin <sp...@paregos.se>]

I've used the IBM xml4j parser before and Iäm thinking of migrating to
Xerces but
I cant even make simple validation correctly, can some one help me???

Should'nt this code produce a parse error on a invalid document??


Java Source:
 org.apache.xerces.parsers.DOMParser parser = new
org.apache.xerces.parsers.DOMParser( );
  Document document;

  ((Configurable)
arser).setFeature( "http://xml.org/sax/features/validation", true );

  parser.setValidating( true );

  parser.parse("d:\\test.xml");

  document = parser.getDocument( );


tem.out.println( document.getDocumentElement( ).getFirstChild( ).getNodeName
( ) );


XML code:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE document SYSTEM "document.dtd">
<document>
<title>bla bla</title>
<text>
bla bla bla
</text>
<ERROR>In valid element</ERROR>
</document>

I'm having trouble finding documentation that provides useful hints like
this one.  Where is it kept?

In general the documentation for Xalan is pretty bad.  I could really
benefit from an explanation of a lot of the terms used, like "connection".
And some examples of how to use it would go a long way.  It's far from
obvious how these tools should be used.

You must register an ErrorHandler to receive notification of
the validity errors.

Just a note, the Configurable interface has been removed in
the latest SAX2 beta. The latest version of Xerces (1.0.2)
supports the new SAX2 API, and therefore doesn't have the
Configurable interface.
