I just finished struggling with this same problem. I had to change
several things to make it work.
You did not say which version of Xerces-J you are using. I urge you to
download 1.4.0 to get the latest schema handling. I did, and my code
examples are based on using version 1.4.0.
My java file contains this code:
DOMParser parser = new DOMParser();
MyErrorHandler errHandler = new MyErrorHandler();
try {
parser.setFeature("http://apache.org/xml/features/dom/defer-node-expansion",true);
parser.setFeature("http://xml.org/sax/features/validation";, true );
parser.setFeature("http://xml.org/sax/features/namespaces";, true );
parser.setFeature("http://apache.org/xml/features/validation/schema",true);
parser.setErrorHandler(errHandler);
parser.parse(xmlFile);
where "MyErrorHandler" is a Java class that I wrote which implements the
ErrorHandler interface.
I tested this using the personal-schema.xml and personal.xsd files that
come with the Xerces package.
My schema file contains this:
<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns='http://www.w3.org/2001/XMLSchema'>
XMLSpy creates schema which contain the string "2000/10", not "2001".
You must edit the .xsd file to change this.
My .xml file contains this:
<?xml version="1.0" encoding="UTF-8"?>
<personnel xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:noNamespaceSchemaLocation='personal.xsd'>
The parser apparently assumes that the schema is in the same directory
as the xml file. If it is not, I had to fully qualify it like this:
xsi:noNamespaceSchemaLocation='file:///c:/xerces-1_4_0/data/personal.xsd'>
I had to do all these things (setFeatures, change "2000/10" to "2001",
and fully qualify the schema location) to get the validation to work.
Good luck.
