Re: [xsl] Transformation using Saxon.Net-1.0-RC1

["M. David Peterson" <m.david.x2x2x@xxxxxxxxx>]

Hi Arthur,

I've been away for the last 18 hours and am just noticing this email.

I have some examples posted to the weblog. >
http://weblog.saxondotnet.org  Its true that with the latest version
of IKVM compiler and runtime you no longer need the ByteArrayHack to
get things to work.  Here is the updated way to write the support
class in C# (the same one listed on the weblog):

using System;

using System.IO;

using System.Xml;

using javax.xml.transform;

using javax.xml.transform.stream;

using net.sf.saxon;





namespace org.x2x2x.Xml

{



  public class Xsl

  {



    public static string Transform(string inXML, string inXSL){



      StreamSource inputXml_Source = new StreamSource(new
java.io.FileInputStream(inXML));

      inputXml_Source.setSystemId(inXML);



      StreamSource inputXsl_Source = new StreamSource(new
java.io.FileInputStream(inXSL));

      inputXsl_Source.setSystemId(inXSL);



      return DoTransform(inputXml_Source, inputXsl_Source);



    }



    private static string DoTransform(StreamSource Xml, StreamSource Xsl){



      java.lang.System.setProperty("javax.xml.transform.TransformerFactory",
"net.sf.saxon.TransformerFactoryImpl");



      StreamResult outResult = new StreamResult();



      java.io.ByteArrayOutputStream outputXmlResult = new
java.io.ByteArrayOutputStream();



      outResult.setOutputStream(outputXmlResult);



      TransformerFactory trans = TransformerFactory.newInstance();



      Transformer transformer = trans.newTransformer(Xsl);



      //transformer.setParameter("dir", "output");



      transformer.transform(Xml, outResult);



      return outputXmlResult.toString();

	

    }

  }

}


Let me know if you have any further issues and I will be happy to get
you going in the right direction.

Cheers,

<M:D/>
