Andrea Marchesini has released libnxml 0.5, a C library for parsing, writing, and creating XML 1.0 and 1.1. libnxml is published under the LGPL.
Todd Ditchendorf has released AquaPath 1.0.3, a free-beer Mac application that can "evaluate XPath 1.0 expressions against any XML document and view the result sequence in a dynamic, intuitive tree representation. AquaPath is based on Apple's Cocoa/Objective-C NSXML and WebKit Frameworks." 1.0.3 adds support for result sequences containing atomic values and now supports all the basic categories of XPath expressions, not just location paths. Mac OS X 10.4 is required.
