[jdom-interest] jdom and dom4j

[Dennis Sosnoski]

dom4j does optionally implement the W3C DOM interface in addition to 
it's custom Java interface (so the same document representation can be 
accessed through both interfaces). In theory I suppose someone could 
write a JAXP interface for dom4j using that DOM interface, but AFAIK 
nobody has done so. I don't know of anything along those lines for JDOM, 
either, though I think there's been speculation that if JDOM becomes a 
Java standard it'll be given equal billing with DOM in JAXP.
