[Xmlunit-general] Schema Validation patch development

[James A. <jam...@gm...>]

I'm writing a patch for consideration that will handle schema validation.

My use case is as follows:

An XML document is generated in some fashion, but it does not contain

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="somenamespace somelocation"

So I would like to set some properties on a Validator like this:

validator = new Validator(new FileReader(xmlFile));
validator.setSchemaNamespace("http://www.example.com/xmlns/books");
validator.setSchemaURL(xsdFile.toURL());
validator.useXMLSchema(true);

validator.assertIsValid();

This is what my patch is aiming to provide. Comments on the API and
intended usage are welcome.

In developing the tests for this patch though, I seem to have hit a
bug, and was hoping someone could help me see what I'm doing wrong.
The below tests fail, although I don't think they should. I can't see
what properties I should be setting that would cause it to pass.


import org.custommonkey.xmlunit.DetailedDiff;
import org.custommonkey.xmlunit.Diff;
import org.custommonkey.xmlunit.XMLTestCase;

public class XMLUnitNamespaceTestCase extends XMLTestCase {

    private String expected = "<root
xmlns='http://www.example.com/xmlns/example'"
        + " xmlns:xsi='http://exampe.com/xmlns/not/schema-instance/namespace'
/>";;
    private String actual =  "<root
xmlns='http://www.example.com/xmlns/example' />";

    public void testNamespaceDifferencesFailViaAssertXMLMethod()
throws Exception {
        assertXMLNotEqual(expected, actual);
    }

    public void testNamespaceDifferencesFailViaDetailedDiff() throws Exception {
        Diff diff = compareXML(expected, actual);
        DetailedDiff detailedDiff = new DetailedDiff(diff);
        assertFalse(detailedDiff.similar());
    }
}

Cheers,

James
