[jdom-interest] entity references replacement

[philip.nelson at omniresources.com]

I think most of what you want is available in the version in cvs now.  SVG
may pose some additional problems though in round tripping because of it's
heavy use of parameter entities and default values.  Give it a try and let
us know what happens.

For reading and writing I use these commands:

SAXBuilder builder = new SAXBuilder(false);
org.jdom.Document document = builder.build(filename);
// xmlOut.setExpandEmptyElements(false/true);

XMLOutputter xmlOut = new XMLOutputter();
xmlOut.setEncoding("iso-8859-1");
xmlOut.setOmitDeclaration(false);
xmlOut.setOmitEncoding(false);
xmlOut.output(document,new FileOutputStream(filename+".optimized.svg"));

I tried to use the setExpandEmptyElements() method but it seems to only
change the handing of the character entities / whitespaces.
How can I prevent the XMLOutputter from replacing the entity references in
the styles?
Any help is appreciated.

Thanks,

Sandro
