[jdom-interest] Fwd: Simple xhtml/entity resolver?

[Oliver Ruebenacker]

    Hello,

  (forwarding this to the list, as I accidentally only sent to Rolf)

 I think there is a misunderstanding. I don't want to output as XML. I
want to render the XHTML as text like a very primitive browser would
display it.

 I'm building a String by traversing the tree by calling
Element.getContent(). For example, a © can be encoded in XML as
"©". Presumably, the Element tree would contain an EntityRef with
name "copy". But what if an XML document contains "&169;" or
"&x00A9;"? How would the EntityRef object look like?

  Thanks!

     Take care
     Oliver
