[jdom-interest] Question about JDOMResult and usage with XMLReader

[Laurent Bihanic]

The SAXException "Ill-formed XML document (multiple root elements detected)" 
is thrown whenever SAXHandler (used by JDOMResult and SAXHandler) is 
processing data that should be added to the current element but no current 
element exists.

This usually signals a bug in an XSLT stylesheet which leads the XSLT 
processor to generate documents with several root elements or with text or 
CDATA sections directly at document level.
