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Error message 'ikvm.lang.ByteArrayHack' is obsolete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,
Arthur
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>
