Help in picking a parser

[Sam Gentile]

I don't have a month. I have a day. Our team leader has resolved it - use
Microsoft's Java classes to do it on both ends.

Particularly if you'll be using Java, you should look at the
package Sun will be providing.  It's not yet on the web, but
should be there later this month.  Includes validating and
nonvalidating parsers ... very fast, robust, conformant.

Alternatively, I usually recomment XP.  It has that same
set of technical advantages, though it doesn't offer any
validation option and is "just a parser".
