import javax.swing.*;
import java.io.*;
import org.apache.xalan.xslt.*;

public class generateClass
{
generateClass(File f)
{
XSLTProcessor processor = XSLTProcessorFactory.getProcessor(new org.apache.xalan.xpath.xdom.XercesLiaison());
XSLTInputSource input=new XSLTInputSource(f.getPath());
XSLTInputSource style=new XSLTInputSource("schema.xsl");
XSLTResultTarget result=new XSLTResultTarget("result.html");
try
{
processor.process(input,style,result);
}
catch(org.xml.sax.SAXException e){}
}

i checked it with xml spy, it tells it well formed and valid.

and here's the message error

XSL Error: Could not parse c:\...\exemple.xml document!
XSL Error: SAX Exception
i really can't see what's the matter

[Ajith Kallambella]

You forgot to close the xsl:stylesheet tag in your xsl. Simply include </xsl:stylesheet> at the end of your xsl file and it should work fine.
Problems like this can be easily solved if you first try to open your XML file in a browser( IE/Netscape). That's exactly what I did and it clearly told me the xsl:stylesheet tag was not closed!! Then I commented out the stylesheet declaration in XML and was able to open the file in IE.
Browsers are great tools for XML development. You should make it a practice to use them.
Cheers!

thanks for the interest in my pb. The </xsl:stylesheet> tag actually is in my xsl, the matter doesn't come from there, and it's still making me crazy.
i don't think the pb comes from the xsl sheet, 'cause i succeed in transforming my xml with that xsl thru xml spy

[aude tantot]

got a clue!
when i load the xml in ie5, only the skeleton xsl appear with no data from the xml, in on the good way i think....

[aude tantot]

for the xalan pb, can it comes from :new org.apache.xalan.xpath.xdom.XercesLiaison()?
