Feature not recognized: - schema validation

[Clarence Schabe]

Hi,

I am using the sample code provided by a link that was suggested in another posting:

HowToValidateXmlAgainstAnySchema that is in the javaRanch wiki.

but I am getting the error:

Feature not recognized: http: //xml.org/sax/features/validation

which was obviously in response to the line of code:

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

Can someone help?

Also, does anyone know how to reference a schema that is just on the local development machine - i.e. the line of code:

parser.setProperty("http: //apache.org/xml/properties/schema/external-schemaLocation",
"http://domain.com/mynamespace mySchema.xsd");

How do I point to my schema if it is only on my local development machine at say c:\myFolder\myXsd.xsd?

Many Thanks!

Hi - me again.

Please ignore the first part of my question regarding feature not recognized - that was just a silly white space issue.

But the second part of my question is still unanswered - how do I point to and .xsd that is just on my local machine - I tried to run the example with this code:

parser.setProperty("http://apache.org/xml/properties/schema/external-schemaLocation", "_tst01.xsd");

where _txt01.xsd is at the level where the program is executing and not surprisingly I get the warning:

[Warning] :-1:-1: SchemaLocation: schemaLocation value = '_tst01.xsd' must have even number of URI's.

So again, how can I point to an .xsd on my local system?

Answered my own question again - just had to use:

parser.setProperty( "http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation", "_my.xsd"); instead

Hello Clarence,

Thanks for your post that i managed to resolve the xml.org/sax... issue.

But my code ...

 import org.apache.xerces.parsers.DOMParser;
import org.w3c.dom.Document;
import org.xml.sax.SAXException;
import org.xml.sax.SAXNotRecognizedException; 
import org.xml.sax.SAXNotSupportedException;  
import java.io.IOException; 
 
public class SchemaValidationExample 
{     
public static void main(String args[]) 
{
DOMParser parser = new DOMParser();
Document doc = null;
String SchemaUrl = "D:/Projects/Tests/ValidateWithXSD/sample/sample.xsd";
String XmlDocumentUrl = "D:/Projects/Tests/ValidateWithXSD/sample/sample.xml";

try 
{    
parser.setFeature("http://xml.org/sax/features/validation", true);     
parser.setFeature("http://apache.org/xml/features/validation/schema", true);
 
parser.setProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation", SchemaUrl);
 
parser.parse(XmlDocumentUrl);    
doc = parser.getDocument();

}catch(IOException e)
{    
System.out.println("Could not read file: " + e.getMessage());

}catch(SAXNotRecognizedException e) 
{    
System.out.println("Feature not recognized: " + e.getMessage());

}catch(SAXNotSupportedException e) 
{    
System.out.println("Feature not supported: " + e.getMessage());

} catch (SAXException e) 
{    
System.out.print("Parsing XML failed due to a " + e.getClass().getName() + ":");    
System.out.println(e.getMessage());
}    
}
} 

Now gives me other error ...


Feature not recognized: <a href="http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation</b rel="nofollow">" target="_blank">http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation[/B]

Can u tell me what might be the issue ? I am using Xerces Impl 2.6.2 if the version matters ...

Thanks in advance ...
