DOM output of an XSLTProcessor as a DOM input to another

[Martín Lahittette <ml...@telpin.com.ar>]

Hi!!
I'd like to use a DOM output of an XSLTProcessor as a DOM input to another
XSLTProcessor. Is it posible?

I tried with this code:

 import org.apache.xerces.parsers.DOMParser;
 import org.xml.sax.SAXException;
 import org.apache.xalan.xslt.*;
 import org.apache.xalan.xpath.xml.XMLParserLiaison;
 import org.w3c.dom.*;
 import org.apache.xerces.dom.*;
 import java.io.IOException;

.......

    org.w3c.dom.Document in, out, end;

    DOMParser parser = new DOMParser();
    parser.parse("catalogo.xml");
    in = parser.getDocument();

    out = test(in);
    end = test(out);
.........

// Process the DOM dom with a stylesheet that produce a copy of the input
DOM.
public org.w3c.dom.Document test(org.w3c.dom.Document dom)  throws
SAXException {
   org.w3c.dom.Document answ;

   XSLTProcessor xsltProc = XSLTProcessorFactory.getProcessor
                 (new org.apache.xalan.xpath.xdom.XercesLiaison());

   answ = new org.apache.xerces.dom.DocumentImpl();
   XSLTResultTarget resultTarget = new XSLTResultTarget(answ);

   xsltProc.process(new XSLTInputSource(dom),
                     new XSLTInputSource("catalogo.xsl"),
                     resultTarget);
   return answ;
}

When I call the test method with 'out', it doesn't work ok. It doesn't throw
any Exception, but the DOM is not correctly processed.
I think the problem is that XSLTProcessor work only with a
DeferredDocumentImpl (as created by the DOMParsed) as input, but it always
produce a DocumentImpl as output (even if I set 'answ' as a
DeferredDocumentImpl)

Any help will be much appreciated...
Thanks, Martin

Ops!! I'm sorry. I had a bug in my stylesheet. XSLTProcessor works fine with
DocumentImpl DOM as input.
Sorry again and thanks.
