Here is your code:

http://bobcat.webappcabaret.net/javachina/faq/xml_java_01.htm#jaxp_sax_Q60

Here is a pair of sample xml and xsd files that you can use to test:

http://bobcat.webappcabaret.net/javachina/faq/xschema_01.htm#schema_Q13

I wrote those several years ago, therefore, I just re-test them, it still works! There was a small problem in the xsd file, which I have fixed it now.

Enjoy!

Thanks for reply sir

But the problem is i am creating xml with the help of a java program
thus sir i don't know how to generate or add a root with xmlns:xsi="....in the Root element these thing like in this
:----

<root xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:noNamespaceSchemaLocation="x.xsd">
...........
</root>

And also i am using jdom instead of sax

i tried following code in this direction but didn't work

Following code giving error

import java.io.File;
    
    import org.jdom.Document;
    import org.jdom.input.SAXBuilder;
    import org.jdom.output.XMLOutputter;
    
    public class Test
    {
        public static void main( String[] args )
        {
            try
            {
                File xmlFile = new File( args[ 0 ] );
                File xsdFile = new File( args[ 1 ] );
    
                SAXBuilder builder = new SAXBuilder(
                    "org.apache.xerces.parsers.SAXParser", true );
    
         builder.setFeature(
         "http://apache.org/xml/features/validation/schema", true);/////**************error 
"http://apache.org/xml/features/validation/schema feature  not provided in org....xerces/.....***********8*/
    
                builder.setProperty(
                    "http://apache.org/xml/properties/schema"
                    + "/external-noNamespaceSchemaLocation",
                    xsdFile.toURL().toString() );
 
  /////**************error "http://apache.org/xml/properties/schema"
                    + "/external-noNamespaceSchemaLocation",
property  not provided in org....xerces/.....************/
  
             Document doc = builder.build( xmlFile );
    
              System.out.println( "Successfully parsed and validated" );
            }
            catch ( Exception cause )
            {
                System.err.println( cause.toString() );
            }
        }
    }

Please do reply

Thanks and Regards

I tried your code with all hopes but unfortunatly It's giving error

I don't know why

Could you tell me the reason

Output is written to the log file C:\PStudio30\MyTesting\SaxValidation.log

You need xerces or xalan on your classpath

This is my build.xml, I am using ant. Please pay attention to the classpath. change it to use your own xalan/xerces location.

<project name="prj" default="comp" basedir="." >
  <property name="xml.home" value="../../tools/xalan-j_2_7_0" />
  <target name="comp">
    <javac srcdir="." >
      <classpath>
        <fileset dir="${xml.home}" 
          includes="*.jar" />
      </classpath>
    </javac>
  </target>
  <target name="validate" depends="comp">
    <java classname="SAXXMLValidatorUsingSchema" fork="yes" >
      <classpath>
    <pathelement location="." />
        <fileset dir="${xml.home}" 
          includes="*.jar" />
      </classpath>
    </java>
  </target>
</project>
