Java XSLT Tranformer: DOMSource vs. StreamSource problem

[Dominique Bejean]

Hello,

I am having a problem doing an XSLT transformation using Java.

I have a XML document as a DOM Document object, wrap the Document object with a DOMSource object, and do the transformation. However, the transformation does not work. None of the templates in the XSLT source are Matched, except for the root template.
The code is as follows:

TransformerFactory tFactory =
TransformerFactory.newInstance;
Transformer transformer = tFactory.newTransformer(new
StreamSource(XslFileName));

transformer.setOutputProperty(OutputKeys.ENCODING,
"UTF-8");
transformer.setOutputProperty(OutputKeys.INDENT, "yes"); transformer.setOutputProperty(OutputKeys.METHOD, "html");

transformer.transform(new DOMSource(m_Root), new
StreamResult(out));

I discovered that if I transform the DOM Document object back into text and wrap the text in a StreamSource, then the transformation works fine. It does not make sense that the StreamSource approach works and the DOMSource approach does not.

I use JDK 1.4.2, Xerces 2.5.0 and Xalan 2.5.2

Can anybody explain what the problem may be?

Thank you for your help.
