This code works :
SAXParserFactory factory =
SAXParserFactory.newInstance();
factory.setNamespaceAware(true);
SAXParser parser = factory.newSAXParser();
Transformer transformer = getXSLTTransform("/
scheda.xslt");
transformer.transform(
new SAXSource(parser.getXMLReader(), new
InputSource(url.openStream())),
new StreamResult(pageContext.getOut()));
So do you think that using dom4j to only transform a document it's
not efficent ? The transform source isn't using some dom-like
internal rapresentation of the XML ?
Thank you
