[jdom-interest] HTML Transformation from xml/xsl

[Laurent Bihanic]

Hi,

JDOMSource allows to directly use a JDOM Document as input for a 
transformation without requiring you to first serialize it to text with 
XMLOutputter.
JDOMResult allows you to convert the output of a transformation into a JDOM 
Document.

In your case, you can not use JDOMResult as the transformation output is HTML, 
not XML. As your input XML is a file, JDOMSource would not help you either 
unless you currently create that file from a JDOM Document just for the 
purpose of applying the transformation. In that case, using JDOMSource will 
boost the performances.
