Differences between Xerces-C++ v2 and v3 branches

Checking the Xerces-C++ webpage, I saw there are two major branches of the parser:

Versi开发者_如何学运维on 2.8.0 and Version 3.1.1

1. What are the main differences between those two? (couldn't find any summary on their page)
2. Which one should I choose for starting a brand new Visual Studio 2010 C++ project?

Thanks for any help

1. already answered by PlasmaHH with migrate to v3

2. There are pre-built binary distributions and ready-made project files for Visual Studio 2010 available only for Xerces-C++ v3.

   Xerces-C++ v2 supports Visual Studio up to version 2005.

   Therefore I suggest to go with Xerces-C++ v3.
