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/>

Hello ,
For basic learning purpose, I'm trying to do a simple transformation, so that
next Saturday I can buy MK's
books, and then get down to the business of using XSL2/XPath with C# (Hoping
to
move on from VB & MSXML.).
First it does not compile.
Error message 'ikvm.lang.ByteArrayHack' is obsolete
Note: Before starting I installed J2SE 5.0 Update 2(jdk1.5.0_02)
Is this to up-todate??
If I comment this out, it compiles. Stepping through the code gives error
Exception Details: javax.xml.transform.TransformerConfigurationException:
Failed to parse stylesheet
An example of a working transformation would help.

Best regards,

For completeness my Code is below
(from example provided by Saxon.NET-ASP.NET-Sample)
<?xml version="1.0" encoding="utf-8" ?>
<saxondotnet_sample>
<message>Hello ASP.NET!</message>
</saxondotnet_sample>
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="html"/>
<xsl:template match="/">
<xsl:apply-templates select="saxondotnet_sample/message"/>
</xsl:template>
<xsl:template match="message">
<xsl:value-of select="."/>
</xsl:template>
</xsl:stylesheet>
