The best place to look for such information: 

There are many parsers there including these:

James Clark has both C and Java parsers available. Freedom of use might be
subject to your making your source available if you redistribute. Read his
(Mozilla) license.

Microsoft makes available an xml parser with source in Java through a
technology partner Datachannel which is freely redistributable:

IBM's Alphaworks has the source to an excellent java xml parser which is
freely redistributable (read the license though!):

James Clark's parsers are well formed parsers, Microsoft and IBM offer
fully validating parsers.

Hope This Helps
