* This sample program parses an XML document as a DOM4J tree using SAX, it then
* creates a W3C DOM tree which is then used as input for creating a new DOM4J
* tree which is then output to SAX which is then parsed into another DOM4J tree
* which is then output as XML.
*
* This is clearly not terribly useful but demonstrates how to convert from SAX
* <->DOM4J and DOM4J <->DOM and DOM4J <->text
