[jdom-interest] Simple xhtml/entity resolver?

[Rolf Lear]

Hi Oliver.

If you already have the XHTML content as JDOM Elements, then you should be
able to (just) do:

XMLOutputter xout = new XMLOutputter();
String fragment = xout.outputString(element);

If you want to change the format of the output (indenting, etc.), you can
add a 'Format' to the XMLOutputter with:

XMLOutputter xout = new XMLOutputter(Format.getPrettyFormat());
String fragment = xout.outputString(element);


I think you may be chasing a red-herring with the Entity References.

The EntityRef code is a 'CYA' implementation, but, in reality, the
SystemID and PublicID are never going to be needed in regular usage.

The only place I know of where you have entity references is if you
specify your input parser should ignore entity-reference lookups when
parsing, and in JDOM you will end up with an EntityRef instead of it's
'underlying' text.
