The latter: http://www.javareport.com/html/products/prod_rev.shtml has a
review of the popular Java XML parsers. The article admitted to being
out-of-date as soon as it was printed, so most of the parsers have been
updated since being reviewed.
The former: part of the point of XML and SGML is their ability to
indicate structure in data that doesn't fit neatly into normalized rows
and tables. The information is structured hierarchically. I know that
Information Builders, a former employer of mine (and Chet Ensign's), has
products that map schema back and forth between relational databases and
their hierarchically-based database products, so the algorithms exist,
but it's not trivial. I haven't heard of anything that does this with
DTDs, but it would be cool.
