This is netscape bookmark parsing, so this is not well formed XML (lots
of tags are not closed). 

demo/xbel/ns_parse.py calls sax2exts.SGMLParserFactory.make_parser(), so
I expect it to return an SGML parser, and not an XML reader.

I'm not too keen on this approach.

I'll give this a try, and keep the list posted. Thanks for your quick
