RE: validating XML with no xmlns

[Oleg Lebedev]

Sorry, I accidentally sent incomplete email. Here is a full version:

 

Greetings.

 

I've been struggling with this problem for the last two days. I am trying to validate an xml document, which does not have any xmlns namespaces set. Here is an example:

 

<?xml version="1.0" encoding="UTF-8"?>
<data>
    <report end-date="11/22/2005" name="My Report" start-date="12/31/1969"/>
    <totals class-avg="0.0" stud-avg="94.0"/>
</data>

 

I have an XSD schema to which this document should conform to. I am using sax parser to validate the document as follows:

 

<BEGIN CODE>

 

            String ns = "http://mynamespace";

            String xsdUrl = "MySchema.xsd";

            SAXParserFactory spfactory = SAXParserFactory.newInstance();
            spfactory.setNamespaceAware(true);
            spfactory.setValidating(true);
            SAXParser parser = spfactory.newSAXParser();
            XMLReader xmlReader = parser.getXMLReader();
            
            // Features
            xmlReader.setFeature("http://xml.org/sax/features/namespaces", false);
            xmlReader.setFeature("http://xml.org/sax/features/validation", true);
            xmlReader.setFeature("http://apache.org/xml/features/validation/schema", true);
            xmlReader.setFeature("http://apache.org/xml/features/validation/schema-full-checking", true);           
            xmlReader.setFeature("http://apache.org/xml/features/validation/schema", true);
            xmlReader.setFeature("http://xml.org/sax/features/xmlns-uris", true);
           
            // Properties
            xmlReader.setProperty("http://apache.org/xml/properties/schema/external-schemaLocation",
                    ns + " " + xsdUrl );

 

            ...

           

            xmlReader.parse(xmlDocUrl);

 

<END CODE>

 

Note that MySchema.xsd file contains the schema with default namespace "http://mynamespace" against which I am trying to validate the document.

 

The last line in the code above always throws an exception:

 

"org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'data'."

 

Could anybody tell me how to validate XML documents with no namespaces specified against XSD schemas?

 

Thanks.
