Re: DOMWrite an HTMLDocument

Hi Roger,

Ah... that is quite novel

Out of curiosity, can you provide the code snippets you use to load the 
generated XSL transformation using XMLC for both XML and HTML 
documents?  This might be functionality we'd want to add to the 
DOMLoader.  Right now the DOMLoader loads documents from classes and either 
a file from the file system or classpath, but does not yet load a stream 
(if that is, in fact, what you are doing).  Anyway, rather than speculate 
on what you are doing, I'll just wait for you to tell me what you are 
doing....and we'll try to get the bug worked out on the XMLC side of things.

thanks,

Jake
