problem with XSLT tranformation using Xalan
Hi, I am very new to Xerces and Xalan.I am using Xerces 2.1.0 and Xalan 1.4.0. Based on one of the examples given on the Apache site, I wrote the below given simple code and got the following error message while transforming a XalanDocument.I am getting -2 as a result of XalanTransformer::tranform() method. Error msg:Fatal Error at (file <unknown>, line 0, column 0): An exception occurred!
Type:RuntimeException, Message:The primary document entity could not be
opened. Id={null}
theResult = -2 Could someone give me pointers as to why this error is caused. A speedy reply would be highly appreciated.Thanks in advance. The code:**************************************************************************// Use the Xerces DOM parser to create a DOM_Document.
#include <parsers/DOMParser.hpp>
#include <dom/DOM_Node.hpp>DOMParser theParser;
// You MUST instruct the Xerces DOMParser NOT to create a DOM_XMLDecNode
// in the DOM to represent the XML declaration. See "Limitations" below.
DOMParser::setToCreateXMLDeclTypeNode(false);
theParser.parse("foo.xml");
const DOM_Document theDOM = theParser.getDocument();// Set up a XercesParserLiaison and use it to wrap the DOM_Document
// in a XalanDocument.
XercesDOMSupport theDOMSupport;
XercesParserLiaison theParserLiaison(theDOMSupport);
XalanDocument* theDoc = theParserLiaison.createDocument(theDOM);// Use the XalanDocument to create an XSLTInputSource object, which
// you can then use in a transformation.
XSLTInputSource theInputSource(theDoc);XSLTInputSource theXSLInput("foo.xsl");XSLTResultTarget theOutput("foo.out");XalanTranformer::intialize();
XalanTransformer theTransformerint theResult = theTransformer.transform(theInputSource,theXSLInput,theOutput);cout << "theresult is: " << theResult ;

So it would seem there are (at least) two methodologies for transforming an
XML document one wants to ensure has been validated.
1. parse and validate foo.xml with Xerces.
pass a XercesDOMWrapperParsedSource version of foo.xml to Xalan.
2. parse and validate foo.xml with Xerces.
transform with Xalan under the assumption that foo.xml has been parsed.
Is the method specified in the usage patterns (i.e., method #1 above) the
recommended method?

Hi David, I tried out the tranformation of an xml file the same way you've stated below and it worked fine. But my requirement is to transform a document of type XalanDocument* . An XSLTInputSource object can be created with a XalanDocument object which can then be passed to the transform() method. But this does not seem to be working and gives me the error that I mentioned. Any ideas what could be causing this error or what I might be missing in my code.

Unless you really need to use the Xerces DOM, you should avoid it. Here's
a much simpler version without it:
XalanTranformer::intialize();
{
XalanTransformer theTransformer;
int theResult =
theTransformer.transform("foo.xml","foo.xsl","foo.out");
cout << "theResult is: " << theResult ;
}
XalanTransformer::terminate();
