Depends what you mean by the "doc." Do you literally want the
nsIDocument object, from which you can enumerate all of the content
nodes in the content tree yourself? Or do you want a serialized
representation of the text in the document (omitting the structure?) Do
you want the state of the document included, so that any dynamic
manipulation and style interpretation has the intended effect? If so,
you certainly don't want to go anywhere near the cache, which holds the
document in its "raw" form. In general, I'd look how we handle the save
and copy operations, and suggest that you grab your data in a similar
fashion.
