I'm using a SAX parser. It doesn't care about the structure of the
overall document. I build the nodes by myself, a tag at a time.

I handle this at the moment, but not in the best way. When my parser
gets to a partial stanza it reads and processes up to the partial
part, it does one of two bad things. The first one is when i get half
a tag or something, and it raises an exception saying it's invalid
XML. The second one is when it lands in the middle of an open tag, but
everything is well-formed, but there's no closing tag. In this case it
parses as far as it can, but without closing tags (which is where I
fire my events) it doesn't DO anything, so it appears to ignore it...
I'm not sure how to fix this.

REXML doesn't have this. There's no way to change the source except to
make a new parser instance.
