 | | | transforming dom with a CDATA section set to null | transforming dom with a CDATA section set to null 2003-01-29 - By Tim Cronin
I'm using Xalan 2.4.1 and xerces 2.2.1.
(I posted to xerces as well...)
I was building a Document and a passed a null to the call createCDATASection
(this did not fail which surprised me..)
when I tried to transform (basically creating a string of the dom)
public static String toString(Node node)
{
StringWriter sw = new StringWriter();
try
{
Transformer serializer =
TransformerFactory.newInstance().newTransformer();
serializer.transform(new DOMSource(node), new StreamResult(sw));
}
catch (TransformerException e)
{
DOMException de = new DOMException(DOMException.SYNTAX_ERR, "failed to
translate DOM");
de.initCause(e);
throw de;
}
return sw.toString();
}
it I got the following
java.lang.NullPointerException

it also failed for xslt transformation

I would expect to get a NullPointerException when I created the
CDATASection.
