I seem to have got a bit further with this
issue. I think it's a Xalan problem so I configured Cocoon to use Saxon instead
which gives me a bit more error detail during the
transformation:

NO.
org.xml.sax.SAXException: Saxon requires an XML parser that reports the
QName of each element
The code that generates the XML that
is passed to the saxon XSLT transformer is:
private void generateDocumentToSAX(String
queryResults)
{
SAXParser parser =
null;
try
{
parser =
(SAXParser)this.manager.lookup(SAXParser.ROLE);
InputSource inputSource = new InputSource(new
StringReader(queryResults));
parser.parse(inputSource, super.xmlConsumer);
}
catch(Exception e)
{
m_resultMessage = "Unable to get parser: " +
e.toString();
this.getLogger().error(m_resultMessage);
}
finally
{
if (parser != null)
this.manager.release(parser);
}
}
Do I need to inform the parser in the code to do something to
stop this error below? WHat is the QName?
