Re: Why does Barracuda choose the way to parse the whole page (*ML) to a doc?

I really suggest that you post these questions to the xmlc list at 
xmlc.enhydra.org.  Barracuda, theoretically, deals with any DOM structure 
that implements the w3c dom.  In practice, pretty much everyone uses XMLC 
and it is used by Barracuda's examples by default.  So, Barracuda has 
little to say about the implementation of the dom structures except that it 
expects them to be w3c dom compliant.

I still don't fully understand the "squeezing" that you speak of, so you 
are going to have to be a bit more clear on that.  Again, the xmlc list 
would be a better place to ask.  There are people there that would be much 
better qualified to answer your questions.  Please don't take this as a 
lack of interest.  I just can't speak to it very much.  It is possible 
that, come Monday, some of the other people on the Barracuda list will have 
more to say about this, so be patient.  The list is usually pretty silent 
over the weekend.
