multiple root nodes

Hi all!

I'm just wondering if there is a way to have multiple root nodes. I seem 
to be getting a "junk after doc" kind of error (do not remember the 
exact error message) when I start on a second root node.
In normal cases this is what to expect, but in my case I'm using expat 
to parse continuously from a socket stream, so multiple root nodes are 
allowed.

Best regards
Daniel
