XML to XML Transformation using XSL and XALAN

[Thushara Perera <thusharap@eurocenter.lk>]

Hi

 

I am using XALAN to transform my XML file to another XML file using XSL. I have a small JAVA program which does this. Does anyone knows How to validate an XML file against the DTD using JAVA ? Is there any methods available in XALAN to implement this ? If yes, could you please send me a sample example of how to it, please ?

 

For your information, my JAVA program that I use to do the transformation is listed below:

 

Your help will be very much appreciated.

 

Thanks a lot

    // system property setting determines the actual class to instantiate -- org.apache.xalan.transformer.TransformerImpl.

 

    XmlToXmlConvertor xmlToXmlConversion = new XmlToXmlConvertor();

 

    xmlToXmlConversion.performTransformation();

  }

 

  public void performTransformation() throws TransformerException, TransformerConfigurationException, FileNotFoundException, IOException
  {
    tFactory = TransformerFactory.newInstance();

 

    // Use the TransformerFactory to instantiate a Transformer that will work with the stylesheet you specify. This method call also processes the stylesheet into

   // a compiled Templates object.

 

    transformer = tFactory.newTransformer(new StreamSource("classes/XslIn.xsl"));

 

    // Use the Transformer to apply the associated Templates object to an XML document (foo.xml) and write the output to a file (foo.out).

 

    transformer.transform(new StreamSource("classes/semicolon.xml"), new StreamResult(new FileOutputStream("classes/foo.xml")));

 

    System.out.println("************* The result is in foo.out *************");
  }
