There's also RapidXML by Marcin Kalicinski (Boost license), which I 
wasn't aware of when Stefan presented his libxml2-based library:

http://rapidxml.sourceforge.net/
http://rapidxml.sourceforge.net/manual.html

Quote: "RapidXml is an attempt to create the fastest XML DOM parser 
possible, while retaining useability, portability and reasonable W3C 
compatibility. It is an in-situ parser written in C++, with parsing 
speed approaching that of strlen() function executed on the same data."

It achieves its high performance, IIUC, by not copying the XML as it 
parses; instead it records pointers into the source text.  This is an 
approach that I have used with other data formats - I recently 
mentioned a const_string_facade class that I have written for this - 
and it works well for me.

It would be great to see some real-life feature-set, performance and 
usability comparisons of this approach and a more traditional parser.  
(Actually there are some numbers in the rapidxml manual linked above, 
but they don't include libxml2).
